Answer:

Rays

Explanation:

The moon was formed about 4.5 billion years ago according to most accepted Giant-impact theory. The Lunar surface has shows the following surface features:

Mares-The dark areas of the moon are filled with lava. These smooth and large areas can be seen from the Earth as well. These are about 3 billion years old.

Crater- These are formed when meteoroid impacts the surface. A depression is formed. Thousands of depressions are present of moon's surface. Lundar surface is continuously bombarded by the small meteors. The largest crater is the Tycho crater.

Mountains and ranges- are the bumps on the surface of the moon. These were formed about 4 billion years ago.

Rills- the cracks present on the lunar surface due to motion of its surface.

Rays- these features were last to form. These are bright rays - streaks of debris which radiate out from large impact craters.

I believe this is electron degeneracy, because the star is essentially having too many reactions too fast and collapses in on itself eventually.

A 1 530-kg automobile has a wheel base (the distance between the axles) of 2.70 m. The automobile's center of mass is on the cen

NeTakaya

Answer:

Force on front axle = 6392.85 N

Force on rear axle = 8616.45 N

Explanation:

As we know that the weight of the car is balanced by the normal force on the front wheel and rear wheels

Now we know that

$F_1 + F_2 = W$

$F_1 + F_2 = (1530\times 9.81)$

$F_1 + F_2 = 15009.3 N$

now we know that distance between the axis is 2.70 m and centre of mass is 1.15 m behind front axle

so we can write torque balance about its center of mass

$F_1(1.15) = F_2(2.70 - 1.15)$

$F_1 = 1.35 F_2$

now from above equation

$F_2 + 1.35F_2 = 15009.3$

now we have

$F_2 = 6392.85 N$

now the other force is given as

$F_1 = 8616.45 N$

Which statements provides evidence that the earth revolves around the sun

Aloiza [94]

Answer:

Different star constellations are visible from Earth at different seasons of the year.

Explanation:

The reason the fact that we can see different constellations in the sky during different seasons on earth is the most compelling reason we travel around the sun is because if the sun travelled around the earth, certain constellations would only be visible in certain places. You’d have to travel to see certain ones.

However, you don’t have to do that because we travel around the sun, therefore travelling around other stars too.

The fulcrum of a first-class lever divides its 9.0 m arm into two sections—a 6.0 m arm and a 3.0 m arm. You place a rock weighin

nexus9112 [7]

For balancing the lever, force on both the sides shall be equal. so,
Force on 3 m end = m × a = 3 × 98.1 = 294.3

Now, on 6 m end, it would be: = 294.3/6 = 49.05
After rounding-off to the nearest hundredth value, it would be: 49 N

Finally, Option A would be your correct answer.

Hope this helps!
