A blue star has the hottest temperature.
Answer: Option B
<u>Explanation:
</u>
Stars are composed of gases which ignite themselves and converge in a spherical shape. Their energy is stored in a specific spherical structure depending upon their gravity. Each star has its own gravity formed by the mass of igneous gas combined to form a star.
They illuminate the cosmic area and their lights can travel much longer distances. The stars can be classified based on spectral frequency or the light they are emitting and also based on their temperature. Thus, the star with the coolest temperature is termed as Red stars and the star with the hottest temperature is termed as blue stars.
Explanation:
It is known that relation between velocity and height is as follows.
v =
where, g = acceleration due to gravity = 9.8
h = height = 0.2 m
Therefore, velocity is calculated as follows.
v =
=
= 3.92 m/s
Also,
Putting the given values into the above formula as follows.
=
=
= m/s
or, = m/s
Thus, we can conclude that recoil speed of the Earth is m/s.
Is going to the west, because momentum is mass in motion so its motion is going to the direction of the netforce. Hope it helps
The last option, Unbalanced.
The claim of the study is that the average attendance at games is over 523.
Under the claim the null and alternative hypotheses are,
After the performing the test, the test yields the results that, fail to reject the null hypothesis.
As null hypothesis is fail to be rejected, then it can be concluded that there is no sufficient evidence to support the claim that the average attendance at games is over 523.
Therefore the correct answer is C: <em>There is not sufficient evidence to support the claim that the mean attendance is greater than 523.</em>
