Ball x of mass 1.0 kg and ball y of mass .5kg travel toward each other on a horizontal surface. both balls travel with a constant speed of 5m/s until they collide. during the collision, ball y exerts an average force with a magnitude of 40 n for 1/6 s on ball x. which of the following best predicts ball y's momentum after the collision?

a. ball y will travel at a speed less than 5m/s in the same direction of travel as before the collision.
b. ball y will travel at a speed less than 5m/s in the opposite direction of travel as before the collision.
c. ball y wil travel at a speed greater than 5m/s in the same direction of travel as before the collision.
d ball y's motion cannot be predicted because the impluse on it is not known.

b.

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
