What is the period of a simple pendulum 80 cm long a- on earth and b- when it is in a freely falling elevator?

none.
when there is gravity
T=2pi square root of L/g
but in a freely falling elevator, there is no accelerate
so it doesn't have period
the answer is none

When elevator move down with acceleration pendulum of bob what is effect on time period?
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.
How does length effect the period of a pendulum?
A longer pendulum has a longer period.
How does height affect the period of a pendulum?
Height does not affect the period of a pendulum.
Which factor affects the period of the pendulum?
The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.
In simple pendulum if string is flexible then what is effect on time period?
multiply the length of the pendulum by 4, the period doubles. the period is proportional to the square of the pendulum length.
What is the period of a simple pendulum 80 cm long on the earth and when it is in a freely falling elevator?
In a freely falling elevator, there would be a period of infinite length, because in freefall, the objects act as if there is no gravity. On earth, the period is given as the quantity 2pi times the square root of the quantity length/g. g is the gravitational constant, which is 9.8 on earth. The period of the pendulum does not depend on how far you pull it back, or how much mass is on the pendulum. Both are common misconceptions. I don't have access to a calculator now, but I will come back to add the actual answer later. Use the formula within the explanation.
A pendulum of the length L is suspended from the ceiling of an elevetor. When the elevator is at rest the period of pendulum is T. What is the period of the pendulum if the elevator is freely falling?
A lift in free fall is the same as a lift with no gravity (e.g. in space), i.e. accelleration due to gravity, g = 0 ms^-2. Now your intuition should tell you what's going to happen but even if it doesn't you can plug this value into your equation for the pendulum's period to find out what happens.
When elevator move down with acceleration pendulum of bob what is effect on time period?
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.
What effect does shortening the length of the pendulum have on the period of the pendulum?
A shorter pendulum has a shorter period. A longer pendulum has a longer period.
What will be the frequency of a simple pendulum in a cabin that is falling freely under acceleration due to gravity?
Well, first of all, we know that the period of a simple pendulum depends on its length. You haven't mentioned any length, and that's an important clue. In this case, the length doesn't matter. A pendulum in free fall, or inside something else that is, doesn't swing. Wherever you put the bob, it just floats there. But you knew that.
How does the period of a pendulum change for length?
A longer pendulum has a longer period. A more massive pendulum has a longer period.
How does length effect the period of a pendulum?
A longer pendulum has a longer period.
How does height affect the period of a pendulum?
Height does not affect the period of a pendulum.
Which factor affects the period of the pendulum?
The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.
In simple pendulum if string is flexible then what is effect on time period?
multiply the length of the pendulum by 4, the period doubles. the period is proportional to the square of the pendulum length.
How can you increase the period of a pendulum?
Increase the length of the pendulum
How much does a pendulum weigh?
A pendulum is a weight suspended from a pivot so it can swing freely. The period of swing of a simple pendulum depends on its length (how far the mass is from the pivot) and is is independent of the mass of the weight. This means that you do not need to worry about the weight except to say that it must be heavy enough not to be disturbed by air currents.
