Abin is doing work by lifting a bowling ball. Which statement could be made about the energy in this situation? It is being transferred from the ball to his arm muscles.
It is being transferred from his arm muscles to the ball.
It would be recorded in units of hertz and power.
It would be cause a change in energy from potential to chemical.

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:

newton's third law, for every action there is an equal and opposite reaction.

hope this : )

um if your asking how to beat a level then that i can with that and how to fix your wii but other than that i can't u
