Answer:
A) r = 20.0 m
B) T = 41.6 s
C) = 6.1 m/s²
Explanation:
A)
- The centripetal acceleration is the one that explains that even though the cyclist is moving at a constant speed, his velocity is changing the direction all the time, keeping him around a circle.
- This acceleration can be expressed as follows:
- Solving for r:
B)
- We can apply the definition of linear velocity, remembering that the period is the time needed to complete an entire circle (T).
- The arc around a circumference (the distance traveled) , is just 2*π*r, so applying the definition of linear velocity, we can write the following expression:
- Solving for T:
C)
- The centripetal acceleration of the car from B) can be found as follows:
Answer:
<h3>The answer is 10 m/s</h3>Explanation:
The average speed of the ball can be found by using the formula
d is the distance
t is the time taken
From the question we have
We have the final answer as
<h3>10 m/s</h3>Hope this helps you
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.
