Ashopper in a supermarket pushes a loaded 32kg cart with a horizontal force of 12 n. how far will the cart move in 3.5 seconds, starting from rest? (disregard friction)

2.297 m

Explanation:

Mass of the cart = 32 Kg.

Force applied to the cart = 12 N.

So, Applying the formula F = ma ,

We get , 12 = 32a

a = 0.375 m/    (acceleration of the cart due to the force applied)

Now , as we know that s = ut + a

Where u is the initial speed which is zero here,

So, s = (0.375)   (Since, time given is 3.5              

                                                                                      seconds)

s = 2.297 m

Thus, distance covered by the cart will be 2.297 m .

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
