1Draw a quick sketch of the object.
2Draw an arrow showing every force acting on the object.
3<span>To calculate the net force, add any vectors acting on the same axis (x and y), making sure to pay attention to the directions.
Hope this helps :)

Explanation:
When the metal bar oscillates between the poles of a magnet, it experience a change in the magnetic flux ( no of magnetic field lines passing through the metal bar) as it enter or leaves the magnetic field of the poles. As we know that the change in magnetic field induces the electric current in the metal bar (conductor). By considering the lenz law which states that the direction of induced current in the conductor will be such that as to oppose the initial magnetic field that is producing it. This opposing force acting on the metal bar will damp the oscillations of the bar between the poles of a magnet.
Yes, in a classical model of the singly-ionized helium atom, a single electron orbits the nucleus.
<h3>What is singly ionized helium?</h3>
Singly ionized helium is an atom that has lost one electrons from its outermost shell. We consider its remaining electron like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom which is the number of protons in the nucleus so the nucleus charge on singly ionized helium is -1.

It’s 180 m/s^2 dude. I think I have you in my class lol.
The amount of exhaust heat discharged per hour from the plant which produces electric energy at the rate of 1. 5 gw, is 9.36×10¹⁹ J/h.
<h3>How to calculate the heat discharged per hour?</h3>
The heat is discharged per hour is equal to the different of total power and actual power.
The plant produces electric energy at the rate of 1. 5 gw. Let assume the efficiency of this power plant is 64% between the temperature of 660 degree C to 330 degree Celsius.
Thus, the maximum efficiency is,
The total power is,
Thus, the heat discharged per hour is,
Multiply the value with 3600 to convert it in s/h,
Thus, the amount of exhaust heat discharged per hour from the plant which produces electric energy at the rate of 1. 5 gw, is 9.36×10¹⁹ J/h.
