Will is a scientist. he’s designing a spacecraft that would allow people to land on mars. will’s mass on earth is 75 kilograms. will knows that the gravitational pull of mars is less than the gravitational pull of earth. when he lands on mars, his mass will 75 kilograms. his weight on mars will be weight on earth.

The best and the most correct answer among the choices provided by the question is the first choice. When he lands on Mars, his mass will be equal to 75 kilograms, but his weight might be less than when he is in Mars. 

Explanation:

First of all, remember that mass is the amount of matter, which has to do with the atoms each of us carries. When we go to the bathroom or sweat a lot, we lose some of that mass, measured in grams (g). If we ingest one liter of water, we will gain one kilogram (kg).

Weight is measured in newton (N), and represents the force with which the earth attracts our mass. That is: gravity (g), measured in m / s², must enter the equation. Here on the planet's surface, it is 9.8 m / s², but can be rounded to 10 m / s². Who has a mass of 60 kg, therefore, weighs 600 N (or P = m.g = 60 x 10, where m is the body mass and g, the gravity of the planet).

To know what one's weight on Mars, simply multiply that person's mass by the gravity of Mars, which is about 3.8 m / s², according to physicist calculations. Thus, we can conclude that Will's mass on Mars will be equal to his mass on Earth, however, Will's weight on Mars will be less than his weight on Earth.

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).
