Proton and neutrons is the answer
Answer:
4.11 s.
Explanation:
The period T of oscillation of the pendulum is given by the formula:
The maximum oscillation point it can reach is 45 °,
This point is the equivalent of T / 4, which is the moment when it reaches equilibrium.
So for T / 4,
It consists of a coil in a constant magnetic field. The current in the coil is the current being measured, and changes the magnetic moment of the coil (given by IA where I is current and A is loop area). This coil's magnetic moment feels a torque in this external magnetic field that moves a needle that tells the observer what the current must be, since the external field is known by the designers of the galvanometer.
