The point with the greatest potential energy is B.
The potential energy of an object is depends on the relative distance between the object and the ground and its mass. The higher the object is from the ground the greater the potential energy posses.
Potential energy (P.E) = mgh
Where m is the mass, g is the gravity and h is the height from the ground to where the object is.
Since the mass and gravity is constant in this case, only the height will determine the point with the greatest P.E and that point is B.
Answer:
Kinetic energy is equals to 0.5mv² where m is the mass in
kilograms and v is the velocity in ms-1
So, for a bicycle of 10kg moving at 10ms-1,
K.E
= 0.5mv²
= 0.5(10)(10²)
= 500 J
Explanation:
Answer:
The ram has done more work because the rate at which the ram work is 1.6m/s and Hari is 1.1m/s
B.Warmer air molecules move faster and get farther apart. As they get farther apart, they become less dense and rise.
