How does the mass of an astronaut change when she travels from earth to the moon? how does her weight change?

Mass does not change

Weight redueces on the moon

Explanation:

The mass of an object never changes with respect to the astronomical body it is on. The mass of an object is the resistance it provides to a force which is applied.

A 1 kg object is an 1 kg object anywhere in the universe.

Weight is the affect of an astronomical object's gravity on it

where,

m = Mass of the object

g = Acceleration due to gravity

=Acceleration due to gravity on Earth = 9.81 m/s²

=Acceleration due to gravity on Moon = 1.62 m/s²

Weight on Earth

Weight on Moon

Dividing the equations we get

The weight of the astronaut on the moon will be 0.165 times the weight on Earth.

So, the weight of the astronaut will be reduced on the moon

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.
