Answer: Dropping a temporary magnet on the floor may destroy its magnetism because <u>the domains are knocked out of alignment</u>
Explanation:
An object behaves as a magnet when all the domains are aligned in a single direction. A temporary magnet is created when domains are temporarily aligned in the presence of another magnetic field. When this magnet is dropped on the floor, the domains dis-align causing the demagnetization of the magnet.
The acceleration of this car is equal to 5
.
<u>Given the following data:</u>
- Initial velocity = 0 m/s (assuming it's starting from rest).
To determine the acceleration of this car:
<h3>How to calculate acceleration.</h3>
In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.
Mathematically, acceleration is given by this formula:

<u>Where:</u>
- U is the initial velocity.
- is the time measured in seconds.
Substituting the given parameters into the formula, we have;

Acceleration, a = 5
