If the truck has a mass of 4,000 kilograms, what is its momentum? express your answer in kg x m/s

0 kg m/s

Momentum is a force that a thing has when it is moving which means when an object is moving only then it will have a non-zero momentum. If an object is stationary, then its momentum is zero.

Formula to calculate the momentum of a moving object multiply the mass of the object times it's velocity.

Momentum = 0 m/s * 4000kg

Momentum = 0 kg m/s

The symbol for momentum is a small p.

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.
