Dropping a bouncy ball and stretching a rubber ban.
Answer:
6.02×10²³
Explanation:
Mole measures the number of particles in a specific substance. The numeric value of a mole for atom or molecules is approximately 6.02×10²³ atoms or molecules.
Answer:
This reduces the average force applied during the landing process/ or you can say it reduces the impact your body takes.
Explanation:
<h2>When a mass on a spring that has been compressed 0.1 m has a restoring force of 20 N , then the value of spring constant (k) :- </h2><h2>200 N/m</h2>
Explanation:
Spring Constant :
According to Hooke's law, The force required to compress or extends spring is directly proportional to the distance it is compressed or stretched.
Given
x = -0.1 m
F = 20 N
F - -kx
k = -f/x
= -20 / -0.1 = 200 N/m
The value of spring constant is 200 N/m.
Answer:
T = 4000 N
Explanation:
We have,
Mass of an elevator, m = 500 kg
It is moving downward with an acceleration of 
. It is required to find the tension force of the cable on the elevator. We know that when the elevator is moving downward, the net force on it is given by :
g is acceleration due to gravity
So, the tension force of the cable on the elevator is 4000 N.
