Suppose the aliens watching the show are on the surface of Mars.

Mass of Mars: 6.42 x 10^23 kg
Radius of Mars: 3.394 x 10^6 m
Calculate;
A) the weight of a 40.0 kg alien on Mars
B) the weight of 40.0kg alien on earh

Earth-sun distance:1.50x10^11m
Mars-sun distance: 2.28 x10^11 m
Earth mass: 5.98x 10^24 kg

Please show all work Bc I don't even know where to being thank you very much appreciated

Sure! Let's start with calculating the weight of a 40.0 kg alien on Mars and Earth.

A) Weight of a 40.0 kg alien on Mars:
To calculate weight on Mars, we can use the formula for the gravitational force:

Weight = mass x acceleration due to gravity

The acceleration due to gravity on Mars can be calculated using the formula:

acceleration due to gravity on Mars = (gravitational constant x mass of Mars) / (radius of Mars)^2

Step 1: Calculate acceleration due to gravity on Mars.
Given:
Gravitational constant (G) = 6.67430 x 10^-11 m^3 kg^-1 s^-2 (universal value)
Mass of Mars (M) = 6.42 x 10^23 kg
Radius of Mars (R) = 3.394 x 10^6 m

Substituting the values into the formula:

Acceleration due to gravity on Mars = (6.67430 x 10^-11 x 6.42 x 10^23) / (3.394 x 10^6)^2

Calculate the result.

Step 2: Calculate the weight of the alien on Mars.
Given:
Mass of the alien = 40.0 kg

Substituting the values into the formula:

Weight on Mars = mass x acceleration due to gravity on Mars

Calculate the result.

B) Weight of a 40.0 kg alien on Earth:
The formula for weight on Earth is the same as the formula for weight on Mars:

Weight = mass x acceleration due to gravity

The acceleration due to gravity on Earth is approximately constant and equal to 9.8 m/s^2.

Given:
Mass of the alien = 40.0 kg

Substituting the values into the formula:

Weight on Earth = mass x acceleration due to gravity on Earth

Calculate the result.

Now that you have the calculations explained, you can follow the steps mentioned using the given values to find the weight of a 40.0 kg alien on Mars and Earth.
