Answer:
the potential energy a massive object has in relation to another massive object due to gravity
Answer:
to get to the other side.
Explanation:
bada bam, bop, BOOM
Answer:
Explanation:
We know that the work could be calculate dby:
W =
where is the component of the force in the direction of the
displacement. and d is the displacement.
So, the total work () is:
Where is the force done by the first tugboat, is the angle of the force, d is the displacement and is the force done by the second tugboat.
Answer:
After 5minutes the temperature in the metal cup will decrease the most
Explanation:
this is because metal is a very good conductor of heat, this property also allows it to lose heat to the surrounding, while plastic and cardboard are insulators and they tend to retain the heat hence the water is warm after 5 minutes.
Answer:
The period of Earth's revolution wouldn't change at all, but certainly we would die because of the cold and lightless space.
Explanation:
A black hole is a lot of matter in a really tiny space, even you could be a black hole, but your matter has to be compressed more than a thousand million two thousand million times a grain of salt and even if that happens I can get close to you as in a normal conversation and I wouldn't fall in the black hole and all of this because your gravitational force wouldn't have change.
So the mass of the sun would remain the same, doing the same gravitational force and keeping the earth on its normal course.
