Question

Calculate frequency of the simple pendulum if the time taken by the bob to reach at one extreme

from another extreme point is 0.25 sec.​

Answer 1

Explanation:

Barium is a naturally occurring alkaline metalloid element with atomic symbol Ba, atomic number 56, and atomic weight 137 that is only found in combination with other elements, typically barite (barium sulfate) and witherite (barium carbonate), or chemicals.

Answer 2

Answer:

2 Hz

Explanation:

time period = time taken to complete 1 osscilation

that is, if a pendulum start from 1 extreme, it should reach the same extreme point and that time for covering that much distance is said to be the time period of simple pendulum

but in qs the time given is half of the time period of pendulum

so given time in qs , that is 0.25 multiplied by 2 gives the time period of pendulum

that is ,

Time period , T = 0.25 * 2 = 0.5 sec

This is the important thing u should note ( most of the people take time period as 0.25 sec ....so u should be aware of this step )

frequency,f = 1 / time period

so f = 1/ 0.5

     = 2
