A piece of metal has a mass of 60 g and a volume of 3 cm^3, what is the density of the metal..?

Work Shown:

density = mass/volume

d = m/v

d = (60 grams)/(3 cubic cm)

d = (60/3) g per cm^3

d = 20 g per cm^3

d = 20 g/cm^3

This means that each cubic centimeter of material has about 20 grams of mass.

A cubic centimeter is a cube that has all sides each 1 cm.

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:

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
