Help fast please!!!!!A new solar system with two planets of equal mass - Planet X and Planet Y - is discovered. Planet X is closest to the sun.

What is the sun's gravitational pull on Planet Y as compared with Planet X?

A.
Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is less than the sun's gravitational pull on Planet X.
B.
The sun's gravity repels Planet Y with more force than it repels Planet X, which is why Planet Y is farther away.
C.
Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is more than the sun's gravitational pull on Planet X.
D.
The sun's gravitational pull on Planet Y is equal to its gravitational pull on Planet X because distance does not affect the sun's gravity.

Answers


We're told that the planets have EQUAL MASS.

If that's true, then the strength of the gravitational forces between
each planet and the star depends only on the distance between
them ... the farther a planet is from the star, the smaller the
gravitational forces are IF we're talking about planets with
equal masses.

Planet-X is closer to the star, and Planet-Y is farther from it. 
From this we know that the gravitational forces between the
star and Planet-X are greater, and the forces between the star
and Planet-Y are smaller.

'A' says this.

'B' is totally absurd, because it talks about gravity repelling things.

'C' says exactly the opposite for the two planets.

'D' says that distance doesn't matter.  We know this is absurd,
simply because we're never pulled toward Jupiter in our daily life.

Hat is the kinetic energy of a 1.0-kg billiard ball that moves at 5.0 m/s? A.
5.0 J

B.
6.5 J

C.
10.0 J

D.
12.5 J

Answers

Kinetic energy is the energy that a body possesses by being in motion. It is calculated by the expression:

Kinetic Energy = 1/2 (mv²)
Kinetic Energy = 1/2 (1 kg) (5m/s)²
Kinetic Energy = 12.5 J

Therefore, the correct answer from the choices above is option D.

Introductory Astronomy1. Light is absorbed and emitted in the form ofwhich are "packets" ofelectromagnetic radiation that carry a specific amount of energy.photonsionsexcited atomsprotons2. Light is characterized by which two properties? point)electromagnetic energy and wavelengthwavelength and frequencyfrequency and radiationOelectromagnetic radiation and gamma rays

Answers

Light ... and all other forms of electromagnetic radiation ... behaves
as if it were a stream of 'packets' that we call 'photons', each one
carrying a specific amount of energy.

Light  ... and all other forms of electromagnetic radiation ... is
characterized by its wavelength.  That is, once you state its wavelength,
you've stated everything there is to know about the light, including its
frequency, and the energy carried by each photon.
