Answer:

longer

Explanation:

The relationship between the solar day and sidereal is as follows:

The length of the sidereal day is

= (Solar day) (solar year ÷ solar year +  1 day)

As it can be seen that the day i.e. solar its length would be greater as compared with the sidereal day.

In the case when the earn orbited the sun in 9 months rather than 12 so here the sidereal day would be the similar but the solar day would be longer as compared with the original one

A cannonball has more kinetic energy than the recoiling cannon from which it is fired because the force on the ball acts over a longer distance.

When a cannon fires a cannonball, both the cannon and the cannonball experience an equal and opposite force (Newton's third law).

However, the cannonball has more kinetic energy because the force on it acts over a longer distance.

The cannonball travels a greater distance in the air, while the cannon's motion is restricted due to friction between it and the ground.

This results in a larger work done on the cannonball, which in turn results in more kinetic energy.

Summary: The cannonball has more kinetic energy than the recoiling cannon because the force acts over a longer distance for the cannonball, resulting in more work done and greater kinetic energy.

Answer:

4s

Explanation:

Using the formula of motion as follows:

V = u + at

Where;

V = final velocity (m/s)

U = initial velocity (m/s)

a = acceleration (m/s)

t = time (s)

Based on the provided information, v = 160m/s, u = 100m/s, a = 15m/s², t = ?

V = u + at

160 = 100 + 15t

160 - 100 = 15t

60 = 15t

t = 60/15

t = 4seconds.

Therefore, the time it takes for the plane to complete this increase in speed is 4s.

The statement is true, the gravitational force that Pluto exerts on Charon acts as a centripetal force for Charon to be able to orbit around Pluto. This is because centripetal force is the force that keeps an object moving in a circular path.

In the case of celestial bodies, such as Pluto and Charon, their mutual gravitational attraction serves as the centripetal force that keeps Charon in its orbit around Pluto. As Charon orbits Pluto, it is constantly changing its direction of motion, which means there is an acceleration towards the center of its circular path (Pluto). This acceleration requires a force, and in this case, that force is the gravitational pull between Pluto and Charon. The gravitational force ensures that Charon maintains its circular orbit and doesn't fly off into space or crash into Pluto.

The average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate. This occurs when the concentration of reactants is constant, and there is no change in the reaction mechanism or conditions.

The average rate of a reaction is calculated by dividing the change in the concentration of the reactants by the time taken for that change to occur. On the other hand, the instantaneous rate of a reaction is the rate at which the reaction is occurring at a particular point in time.

When the reaction is happening at a constant rate, the average rate and the instantaneous rate are the same at any given second. This means that the rate of the reaction does not change over time, and the concentration of the reactants is constant. However, in most cases, the reaction rate changes over time, and the instantaneous rate at any given second is not equal to the average rate.

In conclusion, the average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate.

The mass of the ice that melts when a bullet of mass 4 grams moving at a speed of 3000 meters per second is stopped by an ice block at 0 degrees Celsius is 0.00006 kg.

The kinetic energy of the bullet is converted to heat energy when it collides with the ice block. We can calculate this heat energy as follows:

Initial kinetic energy of the bullet, E = (1/2)mu² = (1/2)×0.004×(3000)² J = 18 J

This is the amount of heat energy that is produced when the bullet collides with the ice block. This heat energy is used to melt a certain mass of ice.

We can calculate the mass of ice melted using the formula for heat of fusion:

Q = mLf

where Q is the heat energy absorbed by the ice, and m is the mass of ice melted.

Substituting the values we get,

18 = m × 300000m = 18/300000 kg = 0.00006 kg

Explanation:

Answer: The meter will read a negative voltage.

Explanation: If you're referring to a voltmeter, which measures the potential difference (voltage) between two points in an electrical circuit, if the positive lead is attached to the negatively charged area (lower potential) and the negative lead is attached to the positively charged area (higher potential), the meter will typically read a negative voltage.

This negative reading doesn't mean that the actual voltage is negative, but rather it indicates that the leads are reversed. The magnitude of the reading would still be the same, but the sign would be opposite.

For example, if there is a potential difference of 5 volts between the two points, with the point attached to the positive lead being at a lower potential, the voltmeter would read -5 volts. The negative sign is indicative of the direction in which current would flow if the two points were connected, which is from the point of higher potential to the point of lower potential.

Mary should speed up at a rate of 70 ms - 2 if she and Sally must crossing an end of the race side by side.

Acceleration refers to the speed at which velocity changes. It's not always the case, but acceleration frequently denotes a shift in pace. The direction of an object's motion is changing, even though it moves in a circular pattern and keeps the same speed.

In physics, acceleration is the rate at which the velocity of the an object changes in relation to time. According to Newton's Second Law, the sum of all loads exerted on an item results in its acceleration. Meter per seconds squared (m s2) is the unit of acceleration used in the SI system.

Work (W) = 4.5x10^5 J

Mass (m) = 1000 kg

Height (h) = 0.8 m

Time (t) = 6 h

1 hour is equal 3600 sec, therefore:

Time (t) =21600 sec

The velocity and direction of the 0.7 kg cart when released = 15 m/s to the right.

The law of conservation of momentum explains that if two objects collide, the magnitude of the decrease in momentum on one object will be equal to the magnitude of the increase in momentum on the other object. This means, the total momentum of the system of objects before the collision is always equal to the total momentum of the system of objects after the collision.

The law of conservation of momentum can be written as follows:

m₁v₁ + m₂v₂ = (m₁v₁)' + (m₂v₂)'

We have,

Mass of the first cart = 1.5 kg ⇒m₁

Mass of the second cart = 0.7 ⇒m₂

The velocity of the 1.5 kg cart = 7 m/s ⇒ v₁'

It moves to the left, so it negative ⇒ -7 m/s

The carts initially at rest, so v₁ = v₂ = 0

And,

(m₁ + m₂) v₂ = (m₁v₁)' + (m₂v₂)'

(1.5 + 0.7) (0) = (1.5) (-7) + (0.7) v₂'

0 = (-10.5) + 0.7 v₂'

0.7 v₂' = 10.5

v₂' = 15 m/s

And 15 m/s ⇒ it is positive, the direction is to the right.

We can solve this problem using the conservation of energy principle, which states that the total mechanical energy (potential energy + kinetic energy) of a system remains constant if no external work is done on the system.

At the top of the hill, the car has only potential energy, given by:

PE = mgh

where m is the mass of the car, g is the acceleration due to gravity, and h is the height of the hill.

PE = (1000 kg) x (9.81 m/s^2) x (200 m) = 1,962,000 J

At the base of the hill, the car has only kinetic energy, given by:

KE = (1/2)mv^2

where v is the velocity of the car.

Using the conservation of energy principle, we can equate the potential energy at the top of the hill to the kinetic energy at the base of the hill:

PE = KE

mgh = (1/2)mv^2

Canceling the mass on both sides, we get:

gh = (1/2)v^2

Solving for v, we get:

v = sqrt(2gh)

Substituting the given values, we get:

v = sqrt(2 x 9.81 m/s^2 x 200 m) = 44.3 m/s

Therefore, the velocity of the car at the base of the hill is approximately 44.3 m/s.
