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.

Answer:
Top(Question 4): A. Increase the duration of walking each day
Bottom(Question 5): C. Evaluate and adjust her choice of activities, frequency, duration, and intensity
Explanation:
<u>Question 4: </u>The principle of progression states that as your body adapts to your exercise routine, you have to change it up. This can mean gradually increasing the weight, duration, or intensity of your weight training to see growth.

Work done = force applied x distance through which it is applied
work done = 0.008 x 25
work done = 0.2 J
So the answer is b. 0.20J
It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. The type of machine that a wire cutter pliers is classified is a simple machine. When we say simple machine, this is the type of machine that is considered basic wherein you need to apply force for it to function. Hope this helps.
