The height of a coffee mug would be about:

500 mm
8 cm
20 cm
0.1 km

8 cm

Explanation:

As we know that standard coffee mug must have fixed dimensions

For a given specific diameter of coffee mug the height of the mug varies from 90 mm to 95 mm

So the maximum height of the coffee mug can not exceed the value of 95 mm as per standard conditions

So here we will have to choose nearest value of height that will be standard for a coffee mug

so it is given as

H = 8 cm

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

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.
