We know that,
kilometre = 1000 metre
1000 can be written as 10³ which is kilo.
Given,
88.0km = 88.0×1000
= 88.0×10³m
b. in non-accelerated motion.
c. free from Earth's gravity.
Answer: B
Explanation:
When in orbit, a satellite is hold in position thanks to, between others, the earth's gravity. So the C option is discarded.
A projectile is an object thrown by the exertion of some force, like a bullet or a cannonball.
A satellite is placed in some orbit, so he can rotate the earth. The movement of the satellite is non-accelerated motion, because the only forces that act on the satellite are the forces that hold him in orbit.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion and is influenced by Earth's gravity.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion.
It is not simply a projectile because it is continuously under the influence of Earth's gravity.
However, it is not completely free from Earth's gravity as it continues to be pulled towards the Earth.

Nuclear energy is released from an atom through one of two processes: nuclear fusion or nuclear fission. In nuclear fusion, energy is released when the nuclei of atoms are combined or fused together. But isn't rapidly release
Answer:
1.12 m/s
Explanation:
We are given that
Diameter of Europa=d=3130 Km
Radius of Europa =
1 km=
Mass of Europa,m=
We have to find the velocity of astronaut on the surface of Europa if her legs are 0.960 m long.
d=0.960 m
Acceleration due to gravity on the surface of Europa
Where
Substitute the values
g
Answer - 75cm=0.075 decametre (divide the length value by 1000.)
75cm=0.00075 kilometer (divide the length value by 100000).
