Answer:
An Ocean beach
Explanation:
a Ocean beach is far heavier than the top of a mountain, despite that a mountain is made with many heavy rocks a Ocean beach may have light sand but the layers of sand and the width would be way heavier then the top of a mountain.
C kinetic energy bc it consists of the total kinetic energy of all its atoms and molecules. It is a form of energy related to heat and temperature
Answer:
(a) 
(b) 
Explanation:
(a) Since a constant external force is applied to the body, it is under an uniformly accelerated motion. Using the following kinematic equation, we calculate the final velocity of the mass if it is initially at rest(
):

According to Newton's second law:

Replacing (2) in (1):

(b) In this case we have
. So, we use the final velocity equation:

Temperature will rise until reaching 0°C.
Twice the amplitude of each wave
