False- the potential energy is force*distance and force is mass*acceleration so if there’s more mass, there’s more force, so there’s more potential energy
Hope that helps :)
Answer:
84kliometers
Explanation:
divide one hundred and sixty eight kilo meters by two hours
Answer:
Explanation:
Givens
delta mv = ?
m = 2 kg
vi = 6 m/s right is positive
vf = - 4 m/s left
Formula
delta mv = m (vf - vi)
Solution
delta mv = 2 * (-4 - 6)
delta mv = 2 * - 10
delta mv = - 20 kg m/s
Answer:
1) Measuring cylinder
2) Top Pan Balance
Explanation:
To find the density of the pebble Nabil should first accurately measure the mass of the pebble using the top pan balance
He should then fill the displacement can till the water reaches the outlet pipe at the to of the cylinder
He should then place the pebble into the cylinder carefully ans allow the water that would start coming out to stop
The volume of water in the displaced cylinder is then measured and the density is found by dividing the mass of the pebble by the volume of water in the measuring cylinder
<span>The elevator must be accelerating

This is the case because the tension is not equivalent to the load's weight, which means there must another force acting on the system.
