Two objects are held close to each other with a compressed spring between them. When the spring is released, one object moves off with a speed of 0.63 m/s, and the other object moves off with a speed of 0.45 m/s. If the faster object has a mass of 0.15 kg, what is the mass of the slower
object?
(A) 0.15 kg (B) 0.21 kg (C) 0.30 kg (D) 0.37 kg
. For the same object as the previous problem, what is the total momentum of both objects just after the spring is released?
(A) 0 kg • m/s (B) 0.095 kg • m/s (C) 0.19 kg • m/s (D) 0.38 kg • m/s

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
