A black hole forms as a star collapses when it ceases emitting radiation from fusion reactions. This occurs after the star has consumed hydrogen, helium, then through iron.

Star evolution refers to the process by which stars evolve (change) over time.

A black hole can be defined as a collapsed star where the gravitational field in its nucleus becomes greater than particles cannot escape from it.

In consequence, black holes are cosmic bodies in which gravity is so powerful that nothing (i.e., particles, radiation, light, etc.) can escape from them.

Nuclear fusion refers to the energy reactions produced by the fusion of hydrogen at the core of a star, thereby becoming helium.

It opens the circuit so that electric charges do not flow to the timer.

When electricity flows over the entire path of an electric circuit, it is said to be closed or complete.

Here,

In a closed circuit, there is no interruption to the flow of electric current through it, because each point in the path of a closed circuit are connected.

When the wire is cut from the bomb, it stopped the countdown timer. This means that, while cutting the wire, the circuit of the bomb, which was a closed electric circuit, became an open circuit.

As a result, the current flow through the circuit is blocked by the open circuit system.

Therefore, the countdown timer of the bomb stopped by cutting the wire.

Hence,

A truck enters a highway driving 60 mph A car enters the highway at the same place 0 nutes later and dives 72 mph in t The car will pass the truck in (Round to the nearest minute) minutes same direction From So the car enters the highway,However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.

To determine how long it will take the car to pass the truck, we can set up an equation based on their relative speeds and distances traveled.

Let's assume that the car passes the truck after time 't' minutes.

In 't' minutes, the truck will have traveled a distance of 60 × (t/60) = t miles.

The car enters the highway 0 minutes later and travels at a speed of 72 mph. Therefore, when the car passes the truck, it will have traveled a distance of 72 × (t/60) = 1.2t miles.

To find when the car passes the truck, we can set up the following equation:

t = 1.2t

Simplifying the equation, we get:

t - 1.2t = 0.2t

0.2t = 0

This equation does not yield a valid solution since it implies that the time required for the car to pass the truck is 0 minutes. However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.

The magnetic field in the solenoid is 0.337 T (to the nearest thousandth).

The magnetic field inside a solenoid can be calculated using the formula:

B = μ₀ * n * I

where B is the magnetic field, μ₀ is the permeability of free space (4π × 10⁻⁷ T·m/A), n is the number of turns per unit length, and I is the current.

In this case, the solenoid has a length of L = 26.0 cm = 0.260 m, a cross-sectional area of A = 0.550 cm² = 0.550 × 10⁻⁴ m², and N = 465 turns. The number of turns per unit length is therefore:

n = N / L = 465 / 0.260 = 1788.5 turns/m

Substituting this, along with the current I = 90.0 A, and the value of μ₀ into the formula, we get:

B = (4π × 10⁻⁷ T·m/A) * 1788.5 turns/m * 90.0 A = 0.337 T

Given:

• Acceleration of rocket = 28.0 m/s²

• Mass of astronaut = 95 kg

Let's find the apparent weight of the astranaut.

In a direct rocket motion, as we are coming towards the Earth the weight reduces while as the rocket is going up, you feel more weighted.

Now, to find the apparent weight of the astranaut, apply the formula:

Where:

Aw is the apparent weight

m is the mass = 95 kg

g is acceleration due to gravity = 9.8 m/s²

a is the acceleration of the rocket = 28.0 m/s²

Thus, we have:

Therefore, the apparent weight of the astranaut is 3.591 kN

ANSWER:

3.591 kN

Answer:

Acceleration, a = 24m/s²

Explanation:

Given the following data;

Initial velocity = 0

Final velocity = 60

Distance =75

To find the final velocity of the object, we would use the third equation of motion;

\( V^{2} = U^{2} + 2aS \)

Where;

V represents the final velocity measured in meter per seconds.

U represents the initial velocity measured in meter per seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

\( 60^{2} = 0^{2} + 2a*75 \)

\( 3600 = 150a \)

\( a = \frac {3600}{150} \)

a = 24m/s²

Acceleration, a = 24m/s²

For a 120/240 volt single-phase dwelling service, if the copper ungrounded conductors are size 3/0 awg, the minimum allowable awg size for the copper grounding electrode conductors is 3 awg.

This is because the NEC code has designated the minimum size of the copper grounding electrode conductor to be equivalent to that of the copper ungrounded conductor. The Grounding Electrode Conductor (GEC) is an essential component of an electrical system since it provides a path for current to flow in the event of a short circuit, which can damage electrical equipment and cause injury or even death.

The minimum size of the GEC for grounding an electrical service is determined by NEC (National Electrical Code) guidelines, which indicate that the size of the copper grounding electrode conductor must be equivalent to that of the copper ungrounded conductor. Disregarding exceptions, if the copper ungrounded conductors of a 120/240 volt single-phase dwelling service are size 3/0 awg, the minimum allowable awg size for the copper grounding electrode conductors is 3 awg.

The type of energy produced when the handle of a pencil sharpener turns is mechanical energy.

The total of an object's kinetic and potential energy is its mechanical energy. You convert your own chemical energy—obtained through food—into the mechanical energy of a pencil sharpener's handle when you turn the handle.

The pencil is then sharpened using this mechanical energy by spinning the sharpening blades, which grinds away the graphite and wood while generating heat and friction. As the handle warms up from friction, some of the mechanical energy is transferred into thermal energy, and some of it is changed into the kinetic energy of the sharpened pencil as it proceeds through the sharpening process.

The weight of an object at the Earth's South Pole is slightly more than its weight at the Equator because the polar radius of the Earth is slightly less than the equatorial radius. Though the mass of an object remains constant, its weight varies according to its location.

Explanation:

Explanation:

The difference between final and initial position of an object is called its displacement. Its formula is given by :

\(\text{displacement}=\text{final position}-\text{initial position}\)

It is equal to the shortest path covered by it. It is a vector quantity. It has both magnitude and direction.

(1) The frequency of the oscillation is 0.32 Hz.

(2) The period of the oscillation is 3.13 seconds.

The period of the wheel's oscillation is the time taken for the wheel to make one complete oscillation.

The period of an oscillatory motion is the reciprocal of the frequency of the oscillation.

The frequency of the oscillation is the number of cycles completed by the oscillatory object in a given second.

The frequency of the wheel undergoing oscillatory motion is calculated by using the following formula.

f = ω / 2π

where;

f = ( 2 rad/s ) / 2π

f = 0.32 Hz

The period of the oscillation is calculated as follows;

T = 1 / f

T = 1 / 0.32 s

T = 3.13 seconds

Thus, the period of oscillation and frequency of the oscillation are inversely proportional.

Answer:

q = 0.384 C

Explanation:

The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:

\(q = ne\)

where,

q = total charge on head = ?

n = total no. of electrons on the head = 2.4 x 10¹⁸

e = charge on 1 electron = 1.6 x 10⁻¹⁹ C

Therefore,

\(q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)\)

q = 0.384 C

To start in motion an object sitting at rest on a horizontal surface, the horizontal force applied must be greater than the static friction force present.

This static friction force is the force that holds the object in place, and is equal to the coefficient of static friction multiplied by the normal force.

Therefore, if an object has a static friction coefficient of 0.2 and a normal force of 10 Newtons, then the minimum horizontal force required to start in motion the object is 2 Newtons.

The static friction is the force that opposes the initiation of motion between two surfaces in contact that are at rest relative to each other. The magnitude of the static friction force depends on the nature of the surfaces in contact and the force pressing them together.

Once the applied force exceeds the static friction force, the object will begin to move, and kinetic friction will take over.

The instantaneous velocity when t = 1 second is 64 ft/s.

To find the instantaneous velocity at a specific time, we need to calculate the derivative of the height function y = 80t - 16t^2 with respect to time (t). The derivative gives us the rate of change of height with respect to time, which represents the velocity of the ball at any given moment.

Taking the derivative of y with respect to t, we have dy/dt = 80 - 32t. This represents the instantaneous velocity of the ball at any time t.

To find the instantaneous velocity when t = 1 second, we substitute t = 1 into the derivative: dy/dt = 80 - 32(1) = 80 - 32 = 48 ft/s.

Therefore, the instantaneous velocity when t = 1 second is 48 ft/s.
