Answer:
690.6 N
Explanation:
The gravitational force that the Earth exerts on Sputnik acts as centripetal force to keep the satellite in motion, so we can write
where
G is the gravitational constant
M = 5.972 x 10^24 kg is the Earth's mass
m = 83.6 kg is the satellite's mass
v = 7574 m/s is the satellite's speed
r is the distance of the satellite from the Earth's center
Solving for r, we find
Now we can find the gravitational force exerted by the Earth on Sputnik:
And according to Newton 3rd law (action-reaction, the force exerted by Sputnik on the Earth is equal to the force exerted by the Earth on Sputnik, so this is the value of the force we are requested to find.
The moon calisto which orbits the planet Jupiter
Answer-Jupiter
Answer:Sample Response: The law of conservation of mass states that the total amount of mass remains constant in a system. In ecology, this means that when an organism is eaten, its mass is conserved. Some of the organism’s mass is used to make new proteins, and some of it is passed as waste in the form of urine or feces. The rest is converted directly into energy. This energy helps the consumer to move and grow, and it helps it to build and repair new tissue.
