A "light year" is not an amount of time.

It's an amount of distance ... the distance that light travels
through space in one year.

1 light year = 5,878,625,372,000 miles
(rounded to the nearest thousand miles)

1 light-year = 9,460,730,473,000 kilometers
(rounded to the nearest thousand kilometers)

Lina20 [59]

Answer: The correct answer is option (C).

Explanation:

As it is given in the problem, the path of a meteor passing Earth is affected by its gravitational force and falls to Earth's surface. Another meteor of the same mass falls to Jupiter's surface due to its gravitational force.

According to Newton's law of universal gravitational, every particle attracts every other particles in the universe with the gravitational force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The Jupiter is the most massive planet in the solar system. It is also the largest planet in the solar system. The gravity of Jupiter on its surface is 2.4 times that of surface gravity of the Earth.

If a person weighs 100 pounds on the Earth then he would weigh 240 pounds on Jupiter.

Therefore, the correct answer is option (C), the meteor falls to Jupiter faster due to its greater gravitational force.

If i have a kinematic equation vf^2=vi^2-2*a(xf-xi), how can i solve for xi step by step

azamat

Answer:

Explanation:

$v_f^2 = v_i^2-2a(x_f-x_i)$

Subtract both sides by $v_i^2$ :

$- v_i^2+v_f^2 = -2a(x_f-x_i)$

Divide both sides by -2*a:

$\frac{v_i^2 - v_f^2}{2a} =x_f-x_i$

Add both sides by $x_i$ :

$x_i+\frac{v_i^2 - v_f^2}{2a} =x_f$

Subtract both sides by $\frac{v_i^2 - v_f^2}{2a}$ :

$x_i=x_f-\frac{v_i^2 - v_f^2}{2a}$

What kind of waves are present during an earthquake? ...

Brrunno [24]

Answer:

1. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

2. potential energy

3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

4. Refraction is the bending of light

5. Density uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). Density is defined as mass per unit volume.

Which of the following statements does not use the term light-year in an appropriate way? A) It's about 4 light-years from here

IRISSAK [1]

Light year is the distance traveled by light in 1 year of time interval

so here we can say that the statement must have used the word light year as the distance

so we have

A) It's about 4 light-years from here to Alpha Century.

this shows the distance between two so it is correct

B) It will take me light-years to complete this homework assignment.

here it represent the light year as time so it is INCORRECT

C) A light-year is about 10 trillion kilometers.

This shows the distance so it is correct

D) It will take the Voyager spacecraft about 20,000 years to travel just 1 light-year.

It shows the distance so it is correct

E) The Milky Way Galaxy is about 100,000 light-years in diameter.

this is distance so it is also correct
