A5.7 kg bucket of water is raised from a well by a rope. the acceleration of gravity is 9.81 m/s 2 . if the upward acceleration of the bucket is 2.2 m/s2 , find the force exerted by the rope on the bucket of water. answer in units of n.

Force exerted by rope will be 68.457 N

Explanation:

Mass of the bucket = 5.7 kg

Acceleration due to gravity

Upward acceleration

We have to find the force exerted by the rope means tension in the rope

Tension in the rope is given by

So force exerted by rope will be 68.457 N

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
