Explanation: i had the same question and i just guessed and got it first try
Answer:
<h2>4.6 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
<h3>
![a = \frac{v - u}{t} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bv%20-%20u%7D%7Bt%7D%20%20%5C%5C%20)
</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
Since the body is from rest u = 0
From the question we have
![a = \frac{23 - 0}{5} = \frac{23}{5} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B23%20-%200%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B23%7D%7B5%7D%20%20%5C%5C%20)
We have the final answer as
<h3>4.6 m/s²</h3>
Hope this helps you
Electromagnets have certain advantages over permanent magnets. One of the major advantage is, the amount of electric current can easily be controlled, in turn, magnetic field can be controlled. Out of all the options, option D would be the best answer.
In short, Your Answer would be option D) Electromagnets can easily be turned on and off.
Hope this helps!
