What would huifen's weight be if her mass is 54kg?

The weight of huifen is equal to 529.2 N.

Explanation:

Given that,

Mass of huifen = 54 kg

We need to find the weight of huifen. We know that, the weight of an object is given by :

W = mg

Where

g is acceleration due to gravity

Put all the values,

W = 54 × 9.8

W = 529.2 N

So, the weight of huifen is equal to 529.2 N.

If you want the true weight of someone, you need to multiply mass by gravity which is 54*9.81 giving the calculation in Newtons and this would equal 529.74N

Explanation:

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.

need to see circuit to get time constant
