Where:
Express the amplitude in meters:
The angular frequency can be found using the next equation:
Using the data provided:
At the equilibrium position:
Answer:
In series
Explanation:
In such experiment, the ammeter is connected in series with the heater, in order to measure the circulating current.
By the way, ammeters are always connected in series in circuits to measure the running current in it.

Answer:
The net charges on inner surface is +3 C
The net charges on outer surface is +7 C
Explanation:
Given that,
Charge on spherical conducting shell = 10 C
Charge at center = -3 C
We know that,
The net electric field inside the conducting shell is zero. The Gaussian surface inside the conductor must have zero net charge.
We need to calculate the net charges on inner surface
The charge on the inner surface of the conductor must be equal and opposite to the present charge of the center.
So, The net charges on inner surface is +3 C.
We need to calculate the net charges on outer surface
Using formula of net charge
Put the value into the formula
Hence, The net charges on inner surface is +3 C
The net charges on outer surface is +7 C
