A.) i.) Mass of Proton is slightly lower than the neutron and electrons are too lighter as compared to them.
ii.) Proton has positive charge, Electron with negative, and neutrons does not have any charge.
iii.) Proton and Neutron resides under the nucleus so known as "Nucleons" whereas electrons revolve around the nucleus.
B.) Protons and Neutrons determine the atomic mass of an atom, and protons and electrons determine the charge upon it. They are the basic properties and many chemical predictions could be made by this information.
Hope this helps!
Answer:
0.00158 A
Explanation:
A = Area of loop = 7.8 cm²
= Final magnetic field = 3.2 T
= Initial magnetic field = 0.5 T
R = Resitance = 
The emf is given by
The current is given by
The resulting induced current in the loop is 0.00158 A
The car's average <em>speed</em> is 97 km/hr.
Then for calculation purposes, we can assume that it covers 97 km in the
first hour, 97 km in the second hour, 97 km in the third hour, and 97 km in
the fourth hour.
All together, the car covers (97 x 4) = <em>388 km</em> of distance.
We don't know the car's velocity, because we have no information about the
<em>direction</em> it moved at any time during the four hours. So we have no way to
calculate how far it was from the starting point at the end of the fourth hour.
For all we can tell, if the direction (and therefore the velocity) varied just right,
the car could have ended up exactly where it started.
