A super-bouncy-ball with a mass of 0.5 kg is thrown at a wall with a velocity of 5 m/s and it bounces back with a velocity of -5 m/s. A no-bounce-ball of the same mass is thrown at a wall at the same
velocity and does not bounce back at all. Which ball experiences a greater change in momentum?
O A the super-bouncy-ball
the no-bounce-ball
o they would have the same change in momentum

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
