Answer: multiply mass and acceleration, unit is N (newtons)
Explanation: law of dynamics: F = ma
In summer because the air in summer is less dense.
Because of the moon and earth. The earth spins on its axis (it's tilted) and the moon orbits the earth every 28 days.
Answer:
Compression in the spring, x = 0.20 m
Explanation:
Given that,
Spring constant of the spring, k = 490 N/m
Mass of the block, m = 5 kg
To find,
Compression in the spring.
Solution,
Since the block is suddenly dropped on the spring gravitational potential energy of block converts into elastic potential energy of spring. Its expression is given by :

Where
x is the compression in the spring


x = 0.20 m
So, the compression in the spring due to block is 0.20 meters.
