Answer:
The new time period is 
Explanation:
From the question we are told that
The period of oscillation is 
The new length is 
Let assume the original length was 
Generally the time period is mathematically represented as
Now I is the moment of inertia of the stick which is mathematically represented as
So
Looking at the above equation we see that
=> 
=> 
=>
It will be 133 on the moon
Mechanical advantage is a quantity that measures how much a machine multiplies force or distance.
Answer:
E = 4410 J
Explanation:
The net energy change is equal to the change in potential energy
ΔPE = mgΔh = 50(9.8)(16) = 7,840 J
However some of that energy went into the stretch of the spring.
that stretch is found setting the spring force equal to the weight
kx = mg
x = 50(9.8)/35 = 14 m
so energy stored in the spring is
PS = ½kx² = ½(35)(14²) = 3,430
energy lost to friction is 7840 - 3430 = 4,410

At higher temperture, length of pendulum clock will be more. So, time period will be more and it will lose the time.
