A 62-kg boy on a 1.5-kg skateboard is moving at 1.2 m/s. The boy steps off the skateboard (Hint: this part is the collision- one thing separating into 2 things is an explosion collision) and now has a velocity of 1.1 m/s. How fast does the skateboard move after he steps off of it?

its c its is a mixture of gases

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:

the bal will not change its velocity.
