Abilliard ball moving at 6.00 m/s strikes a stationary ball of the same mass. after the collision, the first ball moves at 5.12 m/s at an angle of 31.5° with respect to the original line of motion. assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude m/s direction ° counter-clockwise from the original direction of motion

Magnitude : 3.14 m/s

Direction : 301.31 deg

Explanation:

Assuming that the ball moves in positive x-direction initially.

= mass of each ball

= initial velocity of first ball before collision =

= initial velocity of second ball before collision =

= final velocity of first ball after collision =

= final velocity of second ball after collision = ?

Using conservation of momentum

+ =   +

() + () = () +

= () - ()

=

magnitude of final velocity of second ball is given as

magnitude = sqrt((1.63)² + (- 2.68)²) = 3.14 m/s

Direction is given as

θ = 360 + tan⁻¹(- 2.68/1.63)

θ = 301.31 deg

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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
