Question

Calculate the time period of a pendulum whose length is 100 cm.
g=10m​

Answer 1

Answer:

Time period of a simple pendulum with length LL is given by, T=2πLg−−√T=2πLg.

When a pendulum ticks second, each swing is of one second duration. So one oscillation is of two second duration or the time period TT is equal to two second.

From the equation of time period we can calculate the length as L=gT24π2L=gT24π2.

So, L=9.8×224(3.14)2=0.9939mL=9.8×224(3.14)2=0.9939m.

This is approximately equal to one meter.

This pendulum is called seconds pendulum.

Explanation:

Answer 2

Answer:

20sec.

T=2π√l/g;as we know formula.

put the values.

2*3.14√100/10=20 sec.

(take g as 10 or 9.8)optional.
