A motorcycle has a mass of 240 kg and accelerates at a rate of 4 m/s2 Work out the driving force of the motorcycle.
Solution:
Using
F = m a
F = 240 x 4
F = 960 N

960N

Explanation:

Given parameters:

Mass of the motorcycle = 240kg

Acceleration of the motorcycle  = 4m/s²

Unknown:

Driving force of the motorcycle  = ?

Solution:

According to the Newton's second law of motion "the force on a body is the product of mass and acceleration".

    Force  = mass x acceleration

Insert the parameters and solve;

   Force  = 240 x 4  = 960N

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
