more force.
Answer:by increasing any of them,either mass or speed by 1 unit, will result in an increase in energy
Explanation:
By increasing any of them, either mass or speed by 1 unit will result in an increase in energy because kinetic energy is directly proportional to speed and is also directly proportional to mass
The acceleration of the leaf as it falls is zero.
Explanation:
There are to forces acting on the leaf;
(a) force of gravity acting downwards
(b)Air resistance acting upwards
At some point force of gravity acting downwards balances the force of air resistance acting upwards and thus the net force on the leaf is zero.As the net force on the leaf is zero, the acceleration of the leaf =0.
Because of this zero net force, the leaf will acquire a constant velocity after some time called as terminal velocity and will continue to move with this constant velocity.
The second wave because it has the most frequencies. The larger the wave, the more frequencies it has.
Answer: gravitational force
