Answer:
The magnetic field strength and the electrons' energy are 0.077 T and 0.8906 eV.
Explanation:
Given that,
Diameter = 2.62 mm
Frequency = 2.15 GHz
(A). We need to calculate the magnetic field strength
Using formula of the magnetic field strength

Where, f = frequency
e = charge of electron
Put the value into the formula


(B). We need to calculate the energy of electron
Using formula of energy



The energy in eV



Hence, The magnetic field strength and the electrons' energy are 0.077 T and 0.8906 eV.
According to newton's third law of motion, when a hammer strikes and exerts force to push it into a piece of wood, the nail <span>C. exerts an equal or opposite force on the hammer. The third law of motion states that every action has an equal BUT opposite reaction. This means that the nail exerts the same force the hammer exerts on it.</span>
