A) 20 m
<h3>What is called magnitude of displacement?</h3>
The magnitude of displacement is defined as the shortest distance between the initial and final position of the object.
For a particle in motion, the magnitude is either less than or equal to the distance travelled.
Also,
Velocity is simply defined as the rate of change of displacement with time.
Mathematically, it can be expressed as:
Velocity = displacement / time
According to the question,
The following data were obtained:
Time = 5 s
Velocity = 4 m/s
Displacement =?
Velocity = displacement / time
4 = d / 5
D = 4 × 5
D= 20 m
Hence,
20 m is the magnitude of the displacement of the object after it travelled for five seconds.

Answer:
2.45s
Explanation:
is explanation needed too?
The Central pedal force of the wheels center is opposed by an equal force from the objects being spun around by the wheel
False.
Force is found by multiplying mass of an object by its acceleration.
F = mass * acceleration
They are magnetic
