In an experiment you are performing, your lab partner has measured the distance a cart has traveled: 28.4 inch you need the distance in units of centimeter and you know the unit equality 1 inch 2.54 centimeter. by which conversion factor will you multiply 28.4 inch in order to perform the unit conversion?

Conversion Factor = 2.54

Explanation:

Unit conversion refers to the conversion between different units of measurement for the same quantity. Here it is given that the distance is 28.4 inch. This distance needs to be converted to centimeter.

We know that.

1 inch = 2.54 cm

That means we need to multiply the distance by 2.54 to convert the unit of distance to centimeter. This factor is known as conversion factor.

Distance (D) in centimeters is,

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.

i don't know that i agree with that but what's the question ?
