is the gravitational acceleration. As we can see, the period of a simple pendulum depends only on its length.
where L is the length of the pendulum and
Answer:
0.08 w
Explanation:
AVERAGE POWER : Average power is defined as the average work per unit time. average power is denoted by P its depend on the voltage current and power factor.
the expression for the average power is given as
P= cosΦ
We have given maximum voltage =8 volt
=
power factor =.25
resistance =25Ω
power factor =
power factor=
From here Z=100
P= ×
×cosΦ
=5.6577×0.05677×0.25
=0.08w
