What effect does the moon have on the Earth, if any?

Answer:343m

Explanation:

The estimated rise time for the closed-loop navigation system is approximately 1.27 seconds, the estimated settling time is approximately 4.47 seconds, and the estimated percent overshoot is approximately 45.77%.

To estimate the rise time, settling time, and percent overshoot, we need to examine the denominator of the transfer function and determine the system's natural frequency (ωn) and damping ratio (ζ).

The denominator of the transfer function can be written as (s² + 2ζωn s + ωn²), where ωn represents the natural frequency and ζ represents the damping ratio.

Comparing the given transfer function to the general form, we can see that ωn² = 2 and 2ζωn = 2. Solving these equations, we find ωn = √2 and ζ = 0.5.

a) Rise Time:

The rise time (tr) can be estimated using the formula tr ≈ \(\frac{1.8}{\omega n}\). Plugging in the value of ωn, we get tr ≈ \(\frac{1.8}{\sqrt2}\) ≈ 1.27 seconds.

b) Settling Time:

The settling time (ts) can be estimated using the formula ts ≈ \(\frac{4}{\zeta \omega n}\). Plugging in the values of ζ and ωn, we get ts ≈ 4 / (0.5 √2) ≈ 4.47 seconds.

c) Percent Overshoot:

The percent overshoot (PO) can be estimated using the formula

\(PO\approx e^(\frac{-\pi\zeta}{\sqrt(1-\zeta^2)}\times100\)

Plugging in the value of ζ, we get

\(PO\approx e^\frac{(-\pi0.5)}{\sqrt{(1-0.5^2)}}\times100 \approx 45.77\%\)

Therefore, the estimated rise time for the closed-loop navigation system is approximately 1.27 seconds, the estimated settling time is approximately 4.47 seconds, and the estimated percent overshoot is approximately 45.77%. These estimates provide an understanding of the system's dynamic behavior based on the given transfer function.

Upper level divergence region is behind trough

In the upper levels of the atmosphere air tends to flow away from regions of higher pressure and towards regions of lower pressure. this horizontal flow of air is known as the geostrophic wind

The geostrophic wind is flowing away from the low pressure system and towards the region of higher pressure ahead of the trough. as the air flows away from the low pressure system it begins to diverge creating the upper level divergence region behind the trough

Explanation:

She was going at 2km/m, so 2 kilometers per minute. She has 2 minutes therefore she needs to double her rate to 4 kilometers per minute.

Excess electrons that does this person get is -2.87 × 10^14 electrons. Her mass increase by 1.466 × 10^-29 kg.

When a person scuffs her feet on a wool rug on a dry day, she accumulates a net charge of -46 µC. To determine the number of excess electrons that the person obtains, we will use the formula for net charge.

q = ne

Where q is the net charge, e is the charge of one electron and n is the number of electron

Therefore, the number of excess electrons that the person gains is, n = q/e

e = 1.602 × 10^-19 C (charge of one electron)

n = -46 × 10^-6 C/ 1.602 × 10^-19 C/electron

= -2.87 × 10^14 electrons

Her mass increase can be calculated using Einstein's famous equation,

E = mc^2

where, E is the amount of energy released when matter is converted into energy, m is the mass of the object and c is the speed of light

We know that when the electrons are gained, the mass of the person will also increase. The amount of energy released from the mass change can be calculated using Einstein's equation,

E = Δmc^2

where Δm is the change in massc is the speed of light

Einstein's famous equation for matter and energy transformation states that E = mc² which means that matter can be converted into energy or vice versa.

Therefore, the amount of energy released from the mass change can be calculated using Einstein's equation, E = Δmc². Δm is the change in mass of the person.

We know that c = 3.0 × 10^8 m/s.

Therefore, the change in mass can be calculated as,

Δm = E/c²= (-46 × 10^-6 C)(1.6 × 10^-19 J/C) / (9 × 10^16 m²/s²) = -1.466 × 10^-29 kg

The mass of the person increases by 1.466 × 10^-29 kg.

During a warm summer day, a car became extremely hot. when a student went to open the car door, he burned his fingers. Radiation and conduction are the two forms of energy were responsible for the student burning his fingers.

As a mutagen, radiation has the potential to cause cancer in the long run. Radiation has the potential to kill cells or harm their DNA, which will impair their capacity to proliferate and may ultimately result in cancer. In the presence of radiation, your body is exposed to high-energy particles.

Particle vibrations are what trigger this kind of heat transfer in solid materials. A solid's particles start to jiggle, rotate, and vibrate when they are subjected to an energy flow, producing kinetic energy. Heating a skillet on a stove is a typical instance of conduction.

To cure a burn, apply cold, moist compresses or immediately immerse it in cool tap water. Once the discomfort has subsided, repeat this for another ten minutes. Every day, twice to three times, use petroleum jelly. Applying  toothpaste and ointments to a burn could result in an infection.

Answer:

C. 199.9 s

Explanation:

3 minutes = 3×60 = 180 seconds.

the turtle moves in that time 180×10 = 1800 cm.

in other words the rabbit gave it that much head-start (it does not matter if that was at the begin of in the middle of the race).

the rabbit moves with 10×10cm/s = 100cm/s.

the rabbit needs therefore 1800/100 = 18 seconds for the

1800 cm.

at that time the turtle has added another 18×10 = 180 cm.

for which the rabbit needs 180/100 = 1.8 seconds.

during that time the turtle has added 1.8×10 = 18 cm.

and so on.

in formal mathematics this looks like this :

1800 + 10x = 100x

after x seconds of the rabbit running both will have run the same distance, and it is a tie.

1800 = 90x

x = 20 seconds

so, at that point, the rabbit was actively running for 20 seconds and raced 20×100 = 2000 cm

and the turtle was actively running for 180 + 20 = 200 seconds, and also covered 200×10 = 2000 cm.

but our question tells us that the turtle won by 10 cm.

so, the race was over a little bit before these 200 seconds (for a tie).

this means, the rabbit could not run the last 10 cm for the tie (because the race was over and the turtle had won).

the rabbit would have needed 10/100 seconds for these 10 cm.

as speed = distance/time

we need to divide distance by speed

distance/1 / distance/time

to get time.

so,

10cm/1 / 100cm/s = 10s/100 = 1/10 s

so, we need to deduct this 1/10 s from the 200 seconds of the turtle (and also from the 20 seconds for the rabbit).

the race lasted of course the whole time the turtle was running (while the rabbit was resting, officially still participating in the race with speed 0 for 3 minutes).

and so, the race was 199.9 s long.

Answer:

The direction of a moving object will not change if the net force acting on it is zero.

Explanation:

If there is a net force acting on a body, the body may accelerate, slow down, or change direction. In other words, an unbalanced net force may change the state of motion of a body.

The only way a moving object will not change its direction if the body is moving with a constant velocity, meaning all the forces acting on the body are in equilibrium (or balanced). In other words, the net force acting on it is zero, and the speed, as well as direction, would not change.

Therefore, we conclude that the direction of a moving object will not change if the net force acting on it is zero.

The moment of inertia of the modified disk with a hole of radius r centered on the axis is 0.

The moment of inertia of the disk can be calculated using the parallel axis theorem. The moment of inertia of a solid disk about an axis perpendicular to its surface and passing through its center is given by the expression
(1/2)mr^2,
where m is the mass of the disk and
r is its radius.

However, in this case, the disk has a hole of radius r centered on the axis. To calculate the moment of inertia of the modified disk, we need to subtract the moment of inertia of the hole from the moment of inertia of the complete disk.

The moment of inertia of the hole can be calculated separately. Since it is a circular hole, its moment of inertia is given by
(1/2)m(r^2),
where m is the mass of the hole and
r is its radius.

To calculate the moment of inertia of the modified disk, we subtract the moment of inertia of the hole from the moment of inertia of the complete disk:

Moment of inertia of the modified disk = Moment of inertia of the complete disk - Moment of inertia of the hole

= (1/2)mr^2 - (1/2)m(r^2)

= (1/2)m(r^2 - r^2)

= 0

The region of concentrated magnetism at the end of a magnet is called a magnetic pole.

Magnets have two ends, called poles, which are labeled north (N) and south (S). The magnetic field lines of a magnet flow from the north pole to the south pole, creating a magnetic field that can attract or repel other magnets or magnetic materials.

At the ends of the magnet, the magnetic field lines are concentrated and the magnetic force is strongest, creating the magnetic poles. Unlike electric charges, magnetic poles always come in pairs, meaning that every north pole of a magnet is always paired with a south pole. The strength of a magnet's magnetic field depends on the size and strength of its poles.

Answer:

p2=28.12KPa

Explanation:

Given data:

Initial temperature = 295 K

Final temperature= 395 K

Initial pressure = 21.0 KPa

Final pressure = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

21.0 KPa / 295 K = P₂/395 K

P₂ = 21.0 KPa× 395 K / 295 K

P₂ = 8295 KPa. K /295 K

Gravitational potential energy = (mass) x (gravity) x (height)

Kinetic energy (of a moving object) = (1/2) (mass) x (speed)²

When the pendulum is at the top of its swing, its potential energy is

(mass) x (gravity) x (height)

= (5 kg) x (9.8 m/s²) x (0.36 m)

= (5 x 9.8 x 0.36) joules

17.64 joules .

Energy is conserved ... it doesn't appear or disappear ... so that number is exactly the kinetic energy the pendulum has at the bottom of the swing, only now, it's kinetic energy:

17.64 joules = (1/2) x (mass) x (speed)²

17.64 joules = (1/2) x (5 kg) x (speed)²

Divide each side by 2.5 kg:

17.64 joules / 2.5 kg = speed²

Write out the units of joules:

17.64 kg-m²/s² / 2.5 kg = speed²

(17.64 / 2.5) (m²/s²) = speed²

7.056 m²/s² = speed²

Take the square root of each side: Speed = √(7.056 m²/s²) = 2.656 m/s.

Looking through the choices, we're overjoyed to see that one if them is ' 2.7 m/s '. Surely that's IT !

A platinum coil turns becomes a superconductor when immersed in liquid helium at a temperature of 4 kelvin.

Energy from the outside is captured by the circulating fluid running through the coils, which then releases it through the interior coils into the building's interior. Superconductors have no electrical resistance as well as perfect diamagnetism. Cooper pairs of electrons are what cause superconductivity. The BCS theory, so named in honour of its three discoverers, describes how materials transform into "superb conductors" when their internal electrons cooperate to form Cooper pairs (or BCS pairs). When cooled to extremely low temperatures (near absolute zero, or roughly -273° Celsius), conductors completely lose all of their electrical resistance.

Students were asked about the speed of cars involved in an accident. When the verb was changed from "contacted" to "smashed", students were more likely to report that there was broken glass involved in the accident.

A verb is one of the parts of speech in English language and it can be defined as a type of word which is used to describe an action, occurrence, experience, or a state of existence such as, smashed, living, contacted, clean, drive, etc.

Speed can be defined as the distance covered by a physical object per unit of time. This ultimately implies that, the higher the speed of a car that is involved in a road crash or accident, the higher would be the level of impact and damage that would be caused.

In this context, we can reasonably infer and logically deduce that changing the verb from contacted to smashed, ultimately implies that the road crash or accident was ghastly and fatal and such would cause broken glasses in the cars that were involved.

The work done in compressing the spring by an additional 2 cm after compressing it by 2 cm from the equilibrium position is double the work done when it was compressed by 2 cm. When a spring is compressed, some potential energy is stored inside it, which is known as elastic potential energy.

The work done on a spring is the product of force and distance: W = F × d where W is work, F is force, and d is distance. Now, the amount of work done on a spring depends on how much the spring has been compressed. When a spring is compressed by 2 cm from its equilibrium position, some potential energy is stored inside it and the amount of work done isW1 = F × 0.02where F is the force required to compress the spring by 2 cm.

Now, when the same spring is compressed an additional 2 cm, the amount of work done isW2 = F × 0.04where F is the force required to compress the spring by 4 cm. So, the difference in the amount of work done isW2 – W1= F × 0.04 – F × 0.02= F × 0.02= 2F × 0.01= 0.02FTherefore, the work done in compressing the spring by an additional 2 cm after compressing it by 2 cm from the equilibrium position is double the work done when it was compressed by 2 cm.
