Answer:
d) KEe = KEp
Explanation:
According to the law of conservation of energy, the electric potential energy is converted into the kinetic energy of the particle:
Here, q is the particle's charge and V is the potential difference.
The charge of the electron is -e. So:
The charge of the proton is e. So:
So
An insulator is a material that provides resistance to the flow of electric current. Insulators include rubber, plastic, glass since they do not allow electricity to flow through them.
The Electromagnetic ave that is about the size of humans is : A typical micro waves have around 14 inches ( 1.1 meter) in height.
This is very similar to the height of human right before we hit puberty (around 9 - 10 years old)
9W 3V bulb need current flow
I = P/V = 9/3 = 3A
connected serially, voltage drop on the wire will be = Vsupply - 3(Vbulb) = 12 - 3(3) = 3V.
resistance of the wire ,with I=3 and V=3, = V/I = 3/3 = 1 Ohm.
(1/2)(5.0)(v²) = 150
v= 7.75m/s
