The mass of a body if the acceleration the body used to move is given as 5 m/s-2  will be 3 kg.
<h3>What is force?</h3>
Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. 
Force is defined as the product of mass and acceleration. Its unit is Newton.
Given data;
 
Force,F = 30 N
Mass,m =  kg
Acceleration,a = 5 m/s²
The force is found as;
F=ma
30 N =m kg × 5 m/s²
m=3 kg
Hence the mass of a body will be 3 kg.

Answer: Technician B
Explanation: In manual cars,the clutch safety is designed to stop the vehicle from moving when you start the gnition. It prevents power from flowing into the circuit . This is found in the pedal mechanism of cars so depressing the clutch pedal will likely cause a defective in the clutch safety. You will begin to perceive the clutch burning and white fumes coming out from the pedal.

 is the mass measured in kilograms.
 is the mass measured in kilograms.
and
 is the acceleration in metres per second square.
 is the acceleration in metres per second square.
We substitute these values to obtain,
 .
.
We rearrange to get,
 .
.
We multiply out the first two numbers and leave our answer in standard form to get,

The correct answer is C
 
        
             
        
        
        
Work is (force applied) x (distance through which the force moves).
Since the suitcase doesn't move up or down during the 15 minutes, 
no work is done ... zero, zip, nada ... according to the real Physics 
definition of 'work'.
        
             
        
        
        
They both have a magnetic field
