Answer: The person will still have a mass of 90kg on Mars

Explanation: The Truth is, the mass of a body remains constant from place to place. It is the weight which is equal to {mass of body * acceleration due to gravity{g}} that varies from place to place since it is dependent on {g}.

In this case the person will have a Weight of 90*9.8 = 882N on Earth.

{ "g" on Earth is 9.8m/s²}

And a Weight of 90*3.3 = 297N on Mars.

{ From the question "g" on Mars is {9.8m/s²}/3 which is 3.3m/s²}

From this analysis you notice that the WEIGHT of the person Varies but the MASS remained Constant at 90kg.

A 3 kg ball rolls at 2m/s does this system favor kinetic energy or potential energy?
MissTica

Answer:

Kinetic energy

Explanation:

Total energy of any  system is always conserved.

E = K +U

E= Total energy

K = kinetic energy

U = Potential energy

Kinetic energy is the energy acquired by the system due to the virtue of it's motion.

Potential energy is the energy acquired by the system due to the virtue of it's configuration.

Also, Kinetic energy K = \frac{1}{2} m v^{2}

K = \frac{1}{2} \times 3 \times 2^{2}

K = 6 J

The magnetic dipole moment of Earth is 8.00 ✕ 1022 J/T. Assume that this is produced by charges flowing in Earth's molten outer
KonstantinChe [14]

To solve the problem it is necessary to use the concepts and expressions related to the magnetic dipole moment.

It is usually defined by,

\mu = IA

Where,

\mu = Magnetic Dipole Moment

I = Current

A = Area

In this way re-arrange for the current and replacing,

I = \frac{\mu}{A}

I = \frac{8*10^{22}}{\pi R^2}

I = \frac{8*10^{22}}{\pi * (3350*10^3)^2}

I = 7.1285*10^9A

Therefore the current is 7.1285*10^9  Amperes
