A student places blocks on a 100cm long see-saw as shown.

Answer all questions relative to the fulcram.
How much torque is caused by Block A (weight: 4.00N)?

How much torque is caused by Block B (weight: 9.00N)?

How much torque is caused by the see-saw's 7.00N weight?

What will happen to the see-saw?

What is the magnitude of the net torque?

its c its is a mixture of gases

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
