An object weighs 4732 n on earth’s surface. what is it’s mass? 525 kg 469 kg 549 kg 483 kg

 Option D is the correct answer.

Explanation:

Weight of an object = Mass of object x Acceleration due to gravity value.

Mass of an object = Weight of object / Acceleration due to gravity value.

Weight of object = 4732 N

Acceleration due to gravity value of planet earth = 9.8 m/s²

Mass of the object = 4732/9.8 = 482.85 kg = 483 kg

Option D is the correct answer.

483 kg

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.

explanation:

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
