Explanation:
T = 2π √(L / g)
1.0 s = 2π √(L / 19.6 m/s²)
L = 0.50 m
70 Years for the oil to last
Answer:
See explanation below.
Explanation:
Given two blocks of masses M and m, And a force F acting on the block of mass M pulling it outside.
The two masses system can be considered as a whole, With F being the only external force acting on them.
Here the spring force has been ignored as while considering the two system as a whole, it will be accounted as an internal force for the system
Therefore, The acceleration of the system will be:
Now both the masses are moving with this same acceleration towards the direction of force
.
Acceleration of mass m = a (as the system is moving as a whole)
Force on the mass m= mass times acceleration.
Answer:
Explanation:
When I hear "transformation of energy from one form to another", I think of the system exchanging energy with its surroundings. A transformation of energy simply means the system contains a different type of energy than it previously did. One example I can give is a ball. A ball at the top of a hill has a maximum potential energy. If given the chance to roll, it will go to a minimum state of potential. This will convert all of the potential energy into pure kinetic energy, once it reaches the bottom of the hill of course.
Answer:
B) both the amplitude of the motion and the weight of the ball
Explanation:
Time period of a pendulum is given by
where,
L = Length of pendulum
g = Acceleration due to gravity
The system here is similar to a simple pendulum
It can be seen that the time period depends on L and g.
Amplitude and weight are the factors that do not determine the time period.
Hence, the answer is B) both the amplitude of the motion and the weight of the ball
