Answer: time is the same

Explanation: the distance(H) is the same in each case .

we drop the balls , no drag force using basic kimnematics

y =gt*t/2  , yo=0 , vo=0 , y=H  , so : t= sqrt(2H/g)

comment: if distance H starts to grow....we could begin to note a difference  because of gravity g is smaller as we go up

A particle vibrates in Simple Harmonic Motion with amplitude. What will be its displacement in one time-period? A 2A 4A 0
yan [13]

'Displacement' is the distance and direction between the starting point and
ending point, regardless of the path followed to get there.

A particle that's executing simple harmonic motion is always in the same place
where it was one time period ago, and where it will be later after another time
period has passed. 

So its displacement during exactly one time period is exactly zero.

if your vehicle begins to slide or skid in the rear, you should? group of answer choices press the gas pedal and speed up. steer
MariettaO [177]

if your vehicle begins to slide or skid in the rear, you should steer in the direction that the rear is sliding to.

<h3>What should you do if the rear end of the vehicle starts to slide or skid?</h3>

In the case above, a person need to Look as well as steer in the direction that the person want the front of the vehicle to go.

Note that  in the case above;

Do stay way from  the brake pedal and never apply the brakes.

  • Steer in the the same direction as the rear of the vehicle that is known to be  sliding. This will give room for the vehicle to go straight instead of going sideways.
  • Then make sure to get ready to steer in the opposite direction if the vehicle is one that begins swerving in the other direction.

Therefore, if your vehicle begins to slide or skid in the rear, you should steer in the direction that the rear is sliding to.

blsea [12.9K]

Answer:

Voltage, V = 12 V.

Explanation :

It is given that,

The power for the high beam is, P = 60.0 watts

Current flowing, I = 5 A

Car headlights have both low beams and high beams. The high beams may be necessary when it is very dark outside.

So, the voltage required for the high beam is 12 V.
