Exercise is the answer hope i helped you
Answer:
a)1.37 s
b)∞ ( Infinite)
Explanation:
Given that
L= 47 cm ( 1 m =100 cm)
L= 0.47 m
a)
On the earth :
Acceleration due to gravity = g
We know that time period of the simple pendulum given as
Here
Now by putting the values
T=1.37 s
b)
Free falling elevator :
When elevator is falling freely then
( This is case of weightless motion)
Therefore
T=∞ (Infinite)
Because the temperature causes it to go the physical change like if water is froze the temperate just caused it to go through another state of matter another example as if the ice got melted you would need high temperature to cause this change physically. Let me know if I help or if their is anything I can change for you to understand better

When you are driving over a circular bump, you can feel your body moving up a small distance in the seat. This make you feel like you weigh less that you really do. This is caused by the fact that net down force on you is equal to the centripetal force. If you go the following website, you will see a problem that is similar to this one. Go the problem called Sample Roller Coaster Problem.
At this website you can see that the normal force exerted by the seat of the car on a 60.0-kg passenger is equal to the difference of the passenger’s weight and the centripetal force.
Weight = 60 * 9.8 = 588 N
Fc = 60 * 10^2/30 = 200 N
Normal force = 388 N
