Answer: Tides are periodic rises and falls of large bodies of water. Tides are caused by gravitational interaction between the earth and the moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.

The LC circuit will also need a capacitance of 1.01 μF.
<h3>
What is capacitance?</h3>
Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.
<h3>Capacitance needed for the resonance circuit</h3>
Xl = Xc
where;
- Xl is the inductive reactance
Xl = ωL
Xc = 1/ωC
ωL = 1/ωC
ω²LC = 1
C = 1/(ω²L)
C = 1/(2πf)²(L)
C = 1/(4π²f² L)
C = 1/(4π² x 100² x 2.5)
C = 1.01 x 10⁻⁶ F
C = 1.01 μF
Thus, the LC circuit will also need a capacitance of 1.01 μF.

Answer:
The length of the simple pendulum is 2.4 meters.
Explanation:
Time period of simple pendulum is given by :

L is the length of pendulum
The time period of the rope is given by :

L' is the length of the rod, L' = 3.6 m
It is given that, the rod have the same period as a simple pendulum and we need to find the length of simple pendulum i.e.

On solving the above equation as :

L = 2.4 m
So, the length of the thin rod that is hung vertically from one end and set into small amplitude oscillation 2.4 meters. Hence, this is the required solution.
