Answer:
Increases the greenhouse effect and increases the absorption of radiation
Explanation:
An increase in carbon dioxide increases the greenhouse effect and increases the absorption of radiation emitted from Earth's surface. Carbon dioxide has the ability to absorb radiation emitted from Earth's surface. This is because carbon dioxide is an effective heat trapping greenhouse gas.
The force between the two particles will quadruple
Explanation:
The magnitude of the electrostatic force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
d is the separation between the two charges
In this problem, let's call F the initial force between the two charges, when they are at a distance of d.
Later, the distance between the two particles is halved, so the new distance is:
![d'=\frac{d}{2}](https://tex.z-dn.net/?f=d%27%3D%5Cfrac%7Bd%7D%7B2%7D)
This means that the new electrostatic force will be:
![F'=k\frac{q_1 q_2}{(d/2)^2}=4(k\frac{q_1 q_2}{d^2})=4F](https://tex.z-dn.net/?f=F%27%3Dk%5Cfrac%7Bq_1%20q_2%7D%7B%28d%2F2%29%5E2%7D%3D4%28k%5Cfrac%7Bq_1%20q_2%7D%7Bd%5E2%7D%29%3D4F)
Therefore, the force between the two particles will quadruple.

Answer:
v = 0.5 m/s.
Explanation:
Total distance, d = 20 m + 20 m = 40 m
Total time taken, t = 30 s + 50 s = 80 s
The average speed of an object is the total distance divided by time taken. So,
![v=\dfrac{40}{80}\\\\=0.5\ m/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B40%7D%7B80%7D%5C%5C%5C%5C%3D0.5%5C%20m%2Fs)
So, the average speed of the object is 0.5 m/s.
Answer:
You'll see it without noticing
Explanation:
for example: Magnets can pull to one thing, but using the other side of the magnet with the other magnet can push away the magnets, and turn it to their way of pulling, also electricity, movement, were making energy everyday, just by moving
According to x-ray observations, the space between galaxies in a galaxy cluster is very hot. It is because the matter between galaxies (often called the intergalactic medium) is mostly hot, ionized hydrogen with bits of heavier elements such as carbon, oxygen and silicon thrown in.
Massive structures are collapsing than at earlier times. Large collapsing structures lead to higher velocity intergalactic shocks and, as a result, significant intergalactic shock heating, with some gas heated well above the
K temperatures.
Heating also occurs as galaxies expel out most of the gas that fell into them. The final product is a warm/hot phase, with temperatures of >
K.
Now, Let's know how do you use X-rays to make space observations?
X-radiation is absorbed by the Earth's atmosphere, so instruments to detect X-rays must be taken to high altitude by balloons, sounding rockets, and satellites.
