cumulus clouds
Explanation:
Cumulus clouds look like fluffy, white cotton balls in the sky.
Ответ:
Kinetic energy is given by:
K.E. = 0.5 m v²
Susan has mass, m = 25 kg
Velocity with which Susan moves is, v = 10 m/s
Hannah has mass, m' = 30 kg
Velocity with which Hannah moves is, v' = 8.5 m/s
Kinetic energy of Susan:
0.5 m v² = 0.5 × 25 kg × (10 m/s)² = 1250 J
Kinetic energy of Hannah:
0.5 m v'² = 0.5 × 30 kg × (8.5 m/s)² = 1083.75 J
Susan's kinetic energy is 1250 J and Hannah's kinetic energy is 1083.75 J.
Since kinetic energy is dependent on mass and square of speed. Thus, speed has a greater effect than mass. As it is evident from the above example. Susan has greater kinetic energy due to higher speed than Hannah.
