Answer:
The potential difference between the ends of a wire is 60 volts.
Explanation:
It is given that,
Resistance, R = 5 ohms
Charge, q = 720 C
Time, t = 1 min = 60 s
We know that the charge flowing per unit charge is called current in the circuit. It is given by :
I = 12 A
Let V is the potential difference between the ends of a wire. It can be calculated using Ohm's law as :
V = IR
V = 60 Volts
So, the potential difference between the ends of a wire is 60 volts. Hence, this is the required solution.
Answer: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
The nucleus is the center of the atom made up of protons and neutrons with an overall positive charge. this is where the majority of the atom's mass is.
the electron cloud is the energy levels filled with electrons orbiting the nucleus, there is hardly any mass and it has an overall negative charge equal to that of the nucleus it is orbiting if it is part of a neutral atom.
The sun crosses the plane of Earth's equator when the center of
the sun coincides with either of the two points on the map of the
sky labeled "equinox".
One of the following two phenomena occurs at that time, depending
on the direction in which the sun crosses the plane.
1). People all over the northern hemisphere shout and exclaim "It's Spring!",
whereas those in the southern hemisphere yell "It's autumn now.".
2). People all over the northern hemisphere yell "It's Autumn now.", whereas
those in the southern hemisphere shout and exclaim "It's Spring !".
