Answer:

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.

<span>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 be greater to 75 kilograms. His weight on Mars will be lesser than his weight on Earth.

Hope this helps</span>

s344n2d4d5 [400]

Answer: The embryonic period

Explanation:

The embryonic period is the period after implantation roughly starting from week 4 to week 11 , shows the development of the fertilized egg, In this early stage of development , due to the rapid cellular development the formation of body organs and structures like the heart, primitive brain, spinal cord are formed. Three stages occurs in the embryonic stage which include The pre-embryonic stage, the embryonic period, and the fetal period.

Therefore if Manish is studying development of fertilized egg, of which the spinal cord is about to form, then he is most likely observing the The embryonic period.
