Answer:

Orbital radius would decrease because the gravitational pull would increase.

Explanation:

The force of gravity between a star and a planets binds the planet in the orbit around the star. The gravitational force depends the mass of the two bodies and distance between them. More the mass more would be gravitational pull.

If the sun is replaced by the star Betelgeuse which is 20 times more massive, the gravitational pull would be stronger and it would impact the orbital radius of the Earth. The orbital radius of the Earth would decrease.

The vertical velocity of a projectile launch at 35 degree : O continuously decreases O continuously increases O sometimes decrea
kati45 [8]

Answer:Sometime decreases and sometime increases.

Explanation:

Given

Projectile is launched at 35 ^{\circ}

so horizontal velocity=ucos35

vertical velocity=usin35

since gravity acts in the vertical direction, therefore, it affects only the vertical component of the projectile.

So Vertical velocity first decrease up to maximum height and then starts to increase.

Io experiences tidal heating primarily because __________.
Inga [223]

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.

son4ous [18]

Answer:

if you are asking for static friction the answer is  <u>372N</u>

Explanation

friction static=normal force x coefficient of static friction

and normal force is equal to weight of a body

so  static friction = 600N x 0.62= 372N
