Physics
1 answer:
sergiy2304 [10]2 years ago
5 0

Explanation:

Voltage is the electromotive force, or the electric tension. Potential difference is a measure of stored energy of any form. Charge (Q) is the force on a particle in an electric field

A hot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0
iren [92.7K]

Answer:

Y = 40.94m

Explanation:

The initial speed of the sandbag is the same as the balloon and so is its position, so:

Y = Yo + Vo*t-\frac{g*t^2}{2}

Replacing these values:

Yo = 40m     Vo = 5m/s     g = 9.81m/s^2     t = 0.25s

We get the position of the sandbag:

Y = 40+5*(0.25)-\frac{9.81*(0.25)^2}{2}

Y = 40.94m

A 1200-kg car, initially moving at 20 m/s, comes to a stop at a red light over a time of 3 s from the moment the driver hit the
ch4aika [34]

Answer:

Explanation:

Mass of car (M)=1200kg

Initial velocity (u)=20m/s

Stop after time (t)=3sec.

Come to stop implies that the final velocity is zero, v=0m/s

Using newton second law of motion

F=m(v-u)/t

Ft=m(v-u)

Since impulse is Ft

I=Ft

Then, I=Ft=m(v-u)

I=m(v-u)

I=1200(0-20)

I=1200×-20

I=-24,000Ns

The impulse delivered to the car by static friction is -24,000Ns

Gravity will have greater effect on an object with... less force, more mass, less weight, or more change
eimsori [14]
It will have a greater effect on an object with greater mass because G = m * g, where G is the gravitational force, m is mass and g is the acceleration of Earth.
