Why is kg * m ^ 2 / S ^ 3 a unit of power

kg*m^2/s^3＝（kg*m/s^2）*（m/s）
It is easy to see that the above unit corresponds to the expression of (MA) * V, and F = ma, so the above unit corresponds to f * v,
Power P = FV, so the unit in question is the unit of power

Are kg and M / s derived units?

Kg is not. M / S is. It is derived from m and s

What is the volume of water formed by ice, which increases 1.2 cubic decimeter by 10

Let the volume of water be X,
(1+1∕10)x=2,
X = 20 ／ 11 cubic decimeter,
Approximately equal to 1.82

If you want to design a space suit for landing on the moon, what problems do you think you should consider

1. Breathing problem, enough air (pure oxygen will be toxic to man). 2, radiation problem, must be anti radiation. 3, temperature problem, the moon has no atmosphere, the sun (facing the sun, but not necessarily direct) temperature is very high, the dark side is very cold. 4, aircraft, must be able to rely on it to fly. 5, anti shock, prevent the micro meteorite in the universe

After water becomes ice, its volume increases by 1 / 10. How many cubic decimeters is a 143 cubic DM piece of ice turned into water

Volume = 143 (1 + 1 / 10) = 130 cubic decimeter

Suppose you are appointed to design a space suit for astronauts to wear on the moon. What problems might you consider to solve on the moon
Every design should be used to describe the environment on the moon. I'm in a hurry!

1. Breathing problems, oxygen
2. Radiation problem, must be anti radiation
3. Temperature problem, the moon has no atmosphere, the temperature is very high when the sun is direct, and it is very cold when it is not illuminated
4. Aircraft, you must be able to rely on it to fly
5. Anti impact, to prevent the impact of micro meteorite in the universe
6. Take it easy. It's too heavy

When water forms ice, its volume increases by 1 / 10. After a 143 cubic decimeter piece of ice turns into water, what is its volume? How many cubic decimeters

143÷(1+10%)=130

If you want to design a kind of spacesuit for astronauts on the moon, what problems do you have to consider to solve on the moon?

1. Big temperature difference between day and night 2. No oxygen, no air 3. No sound

A rectangular steel plate is 4 decimeters long, 3.5 decimeters wide and 16 cm thick. How many cubic decimeters is the volume of this steel plate? How many cubic meters
Good hearted man, help that one

16cm = 1.6dm
Volume = 4 × 3.5 × 1.6 = 22.4 cubic decimeter = 0.0224 cubic meter

Why do astronauts wear special spacesuits when landing on the moon

Atmospheric pressure oppresses you from all directions all the time on the earth, but the evolution of hundreds of millions of years makes you have the same pressure as atmospheric pressure, from the inside to the outside. There is no atmospheric pressure on the moon, so the astronauts without spacesuits will explode because of the internal blood pressure. In addition, because there is no atmosphere on the moon to block the loss of sunlight and heat, the temperature difference between day and night can't bear
