Answer:
Acceleration due to gravity will be
Explanation:
We have given length of pendulum l = 55 cm = 0.55 m
It is given that pendulum completed 100 swings in 145 sec
So time taken by pendulum for 1 swing
We have to find the acceleration due to gravity at that point
We know that time period of pendulum;um is given by
So
Squaring both side
So acceleration due to gravity will be
The answer is D.) all of the above
Yes they are the power goes from one to another and if one goes off another will go off too
Answer: 100 m/s^2
F=ma
Explanation:
50N = 50 kg*m/s^2
500g = 0.5 kg
F=ma
a = F/m
a = (50 kg*m/s^2)/(0.5 kg)
a = 100 m/s^2
