Why does Earth's moon have no atmosphere? A. The average temperature is too high.
B. There are no plants to release oxygen.
C. The moon is too far away from Earth.'
D. The moon's gravity is too weak t hold onto gas molecules

Answers

You can eliminate the answer A because the moon is super cold
For answer B, atmosphere is contained of gasses, not just oxygen alone
Definitely not C
The answer is D because the moon's gravity isn't strong enough to hold the gasses, as a result, only a small amount of gasses has an attraction to it ( the moon has a little atmosphere though) but not enough to be considered

The moon does not have an atmosphere hence it has no magnetic field and is too small to have an atmosphere. Another reason why is because the moon has a weak gravitational field. Gravity helps the moon hold on to its atmosphere, the moon is small leaving no atmosphere on the moon.

Your answer is D. The moon almost has no gravity thus it cannot hold onto the gas molecules. The gravity on earth is in fact weak which is also the other reason it cannot hold onto the gas molecules. Your answer is most definitely D, The moon's gravity is too weak to hold onto gas molecules.

This is all in my own words you can research as hard as you want you should not find anything that is the exact same thing as what i have written unless it is on brainly on this question.

I hope this helps. If it does please consider hitting the crown in the bottom right corner of my answer. This will give me something called "Brainliest". Remember that you cannot mark me as brainliest if i am the only answer you must wait for another person to answer your question before giving me brainliest.

Need help in the future? I am willing to help with any questions you may have. I may not be able to answer it although. I will have to research it and learn it before i answer it if i do not know how to answer it.

Which describes what happens when a balloon is rubbed with a wool cloth?A.
Electrons move from the atoms in the balloon to the atoms in the cloth, causing the cloth to have a negative charge.

B.
Everyday objects do not have electric charges, so neither the balloon nor the cloth can gain or lose electrons.

C.
Electrons move from the atoms in the cloth to the atoms in the balloon, causing the balloon to have a negative charge.

D.
Electrons are shared equally between the atoms of the balloon and the atoms of the cloth, making both electrically neutral.

Answers

the correct answer would be a hope this helps :D

The answer is C. because when you rub the balloon on the wool the electrons move from the balloon to the wool.

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.7 1010 m (inside the orbit of Mercury), at which point its speed is 9.5 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.)

Answers

Answer:

58515.9 m/s

Explanation:

We are given that

$d_1=4.7* 10^(10) m$

$v_i=9.5* 10^4 m/s$

$d_2=6* 10^(12) m$

We have to find the speed (vf).

Work done by surrounding particles=W=0 Therefore, initial energy is equal to final energy.

$K_i+U_i=K_f+U_f$

$(1)/(2)mv^2_i-(GmM)/(d_1)=(1)/(2)mv^2_f-(GmM)/(d_2)$

$(1)/(2)v^2_i-(GM)/(d_1)+(GM)/(d_2)=(1)/(2)v^2_f$

$v^2_f=2((1)/(2)v^2_i-(GM)/(d_1)+(GM)/(d_2))$

$v_f=\sqrt{2((1)/(2)v^2_i-(GM)/(d_1)+(GM)/(d_2))}$

Using the formula

$v_f=\sqrt{v^2_i+2GM((1)/(d_2)-(1)/(d_1))}$

$v_f=\sqrt{(9.5* 10^4)^2+2* 6.7* 10^(-11)* 1.98* 10^(30)((1)/(6* 10^(12))-(1)/(4.7* 10^(10)))$

Where mass of sun= $M=1.98* 10^(30) kg$

$G=6.7* 10^(-11)$

$v_f=58515.9 m/s$

if you walk 6 blocks east, 2 blocks north, 3 blocks west, and 4 blocks south, then ehat is the total distance you travel?

Answers

To calculate the total distance traveled, we need to consider the distances traveled in each direction. Let's break it down step by step:

1. Walking 6 blocks east: When you walk 6 blocks east, you cover a distance of 6 blocks.

2. Walking 2 blocks north: After walking east, you then walk 2 blocks north. This adds an additional distance of 2 blocks.

3. Walking 3 blocks west: Next, you turn and walk 3 blocks west. This cancels out part of the distance you covered while walking east. So, you subtract 3 blocks from the total distance.

4. Walking 4 blocks south: Finally, you walk 4 blocks south. This cancels out part of the distance you covered while walking north. So, you subtract 4 blocks from the total distance.

To calculate the total distance traveled, we can add up the distances traveled in each direction:

Distance traveled east: 6 blocks

Distance traveled north: 2 blocks

Distance traveled west: -3 blocks (subtracting 3 blocks cancels out part of the distance traveled east)

Distance traveled south: -4 blocks (subtracting 4 blocks cancels out part of the distance traveled north)

Now, we can add these distances together:

6 blocks + 2 blocks + (-3 blocks) + (-4 blocks) = 1 block

Therefore, the total distance you travel is 1 block.
