2. For one complete oscillation, a pendulum (of any length) always
a. Takes different time b. takes same time e has same speed​

Answer 1

Answer:

a. takes different time

Answer 2

For one complete oscillation, a pendulum (of any length) always:

• takes same time.

But why ?

• First of all, let's learn the expression for time period of a pendulum.

• $\bf T = 2\pi \sqrt{\dfrac{l}{g}}$

• So, in the expression, when a length of pendulum and the gravitational acceleration value has been specified and made constant, the final value of T becomes constant.

• In other words, simple harmonic motion of a pendulum is a periodic motion, the time period will always be same, provided the length and "g" is constant.

• Time period means the time taken to complete one full oscillation, and yes, it will be same for the specified conditions.
