An object has a kinetic energy of 35j and a mass of 24j kg, how fast is the object moving?

v = 1.7 m/s

Explanation:

We have,

The kinetic energy of the object is 35 J

Mass of the object is 24 kg

It is required to find the speed of the object. If v is the velocity, then kinetic energy is given by :

or

So, the speed of the object is 1.7 m/s.

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.
