Answer:
Scalar quantity is the Physical quantity expresed only by their magnitude.
Answer:
0.4 m/s
Explanation:
Law of conservation of momentum tell us that the change in momentum of the hammer will be equal to the change in momentum of the astronaut
change in momentum of hammer = change in momentum of astronaut
2 kg (14 m/s - 0 m/s) = 70 kg * (v-0)
v = 0.4 m/s
∆x (displacement) = v - u
where, v is the final position and u is the initial position.
Given, the final position of the object is 0 m and the initial position is 5 m.
∆x (displacement) = v - u
= 0 m - 5 m
= -5 m
Therefore, <u>C: -5m</u> is the correct answer.

Our skelotns would have to change as, they require less pressure and so on. Even now we can only survive a certain time in space.
