Answer:
acceleration in the new orbit is 8 time of acceleration of planet in old orbit
Explanation:
given data:
radius of orbit = R
Speed pf planet = v
new radius = 0.5R
new speed = 2v
we know that acce;ration is given as
acceleration in the new orbit is 8 time of acceleration of planet in old orbit
Answer:
the orbit of Io around Jupiter causes the tidal heating.
Explanation:
Io's elliptical orbit causes the tidal force to vary as it orbits Jupiter.
Because Jupiter is a very massive planet, it has a very large gravitational pull on its moons, so the side of Io facing the planet is experiencing a greater gravitational pull than the opposite side. This causes a distortion in the shape of the Io, and a friction that causes the tidal heating.
This friction generates heat currents, which is what makes Io the place with the most volcanic activity in the solar system.
Answer:
As the car travels up the coaster it is gaining potential energy.
Explanation:
Because It has the greatest in amount of potential energy at the top of the coaster. when the car travels down the roller coaster it obtains speed and kinetic energy.
'Newton-second' is dimensionally equivalent to 'kilogram-meter/second'.
