Answer:
What evidence supports their claim.
Explanation:
In the end, all that really matters in an experiment, is what scientific evidence supports the claim being made.
<h3>
Answer:</h3>
15 ohms
<h3>
Explanation:</h3>
- The effective resistance of resistors is calculated depending on whether the resistors are arranged in series or parallel.
- The effective resistances of resistors in parallel is calculated using the formula;
In this case we are given,
Effective resistance, Rt as 5.0 Ω
First resistor has 10 Ω
second resistor has 30 Ω
We are required to calculate the resistance of the third resistor;
But, effective resistance for parallel arrangement is given by;
Then;
Thus;
Therefore;
Thus, the resistance of the third resistor is 15 ohms
Answer:
τ = 15N.m
Explanation:
Torque on the rod is given by:
If you were told that gravity contributes as well, and you were given the mass of the rod, you would have to subtract the torque of the weight to this value.
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
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
