Answer:
k = 100 N/m
Explanation:
The elastic potential energy of a spring is equal to (1/2)kx^2, where k is the spring constant and x is the distance compressed. If the elastic PE is equal to 2J, we can solve for k. Make sure to convert units from cm to m:
(1/2)kx^2 = 2J
kx^2 = 1
k = 1/x^2
k = 1/(0.1)^2
k = 100 N/m
One factor that drives atmospheric circulation is the movement of air from warm equatorial areas to cooler areas.
This is true.

Explanation:
It is important that a football defender should have a lot of mass because of Defenders are aggressive .
- They aren't afraid to make strong tackles and use their body.
- They attack balls with their heads and get in front of shots.
- Play so aggressive that players are scared to receive the ball.
• The role of the first defender is further broken down into four steps :- Approach , Delay , Control and Tackle ..

In order to know how long it has been falling for you take the final velocity "49m/s" and divide it by the acceleration "9.8m/s" and get 5, since you have been using seconds in the calculations the answer is 5 seconds. (Fun fact, it is actually 9.82m/s per second since it accelerates and they rounded it down.)
