Answer:
P = 22 watts
Explanation:
Given that,
The output power of the generator = 2 a
The output potential difference = 11 V
We need to find the output power of the generator. The formula for the output power is given by :
So, the output power of the generator is equal to 22 Watts.
Initial velocity =0, a=3m/s2, final velocity =18m/s, 18=3t, t=6 sec
The power delivered to the coil is 0.5 Watts
<h3>Resistivity of a material</h3>
The formula for calculating the power delivered to it is expressed according to the equation
Power = I²R
where
I is the current
R is the resistance
Given
Current = 0.500A
Determine the resistance using the resistivity formula
R = ρL/A
Substitute the given parameters
R = 10^-6*(25)/0.002²
R = 2ohms
Substitute
Power = I²R
Power = (0.5)²(2)
Power = 0.5watts
Hence the power delivered to the coil is 0.5 Watts

Answer:
c. The force on the charge at the origin is 0
Explanation:
We know by Coulomb's law:
Force between to two charges (here repulsive since both are +ve) sperated by distance 'r' in space is:
where:
= permittivity of free space
being the charges
In this case the product remains constant and also the distance "r" is constant which yields the force identical in each case.
Since identical charges are kept at all the four corners of a diamond shape and are equidistant from the origin where another charge of +5 μC is kept, all the charges from the vertices will apply equal repulsive force on the charge at origin cancelling out the force vectors which yields the force to be zero.
The current is sent through transformers to increase the voltage to push the power long distances. The electrical charge goes through high-voltage transmission lines that stretch across the country. The electricity travels through wires inside the walls to the outlets and switches all over your house.
