Aperson is pulling a 20kg crate. if the frictional force is 50n, and the crate is accelerating at 2m/s^2, what is the tension in the rope?

The tension in the rope is 90 N.

The person pulls the crate of mass m using a rope. The rope is under a tension T. The ground exerts a force of friction f on the crate.The force of friction is directed opposite to the motion of the crate. The crate accelerates in the direction in which the person pulls with an acceleration a.

Write the force equation for the motion of the crate.

Therefore,

Substitute 20 kg for m, 2m/s² for a and 50 N for f in the equation and calculate T.

The tension in the rope is 90 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
