Identify the type of motion for each number Situation Type of Laws of Motion
1. Throwing garbage on the river would go back to the community during the flood season.
2. It is easier to push an empty shopping cart than a loaded one.
3. The baseball is thrown into the air after being hit by the bat.
4. When walking, your foot pushes the ground backward, and the ground pushes your foot forward.
5. A runner who reaches the finish line must continue running for some time.

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.
