The sun is a ball of hot gases containing different kinds of elements at different cores. It has a very high temperature that radiates all throughout the Milky Way galaxy. The sun has three main parts; photosphere, chromospheres and corona. The outer core of a star located at the chromospheres contains mostly of hydrogen. Inside the hydrogen is helium then carbon, oxygen, neon, magnesium silicon and the inert gas. The photosphere is scattered by the loose electrons in the corona’s plasma.

How does mass affect density? How does volume affect density?

Musya8 [376]

Answer:

Here's the Density Formula: D = M/V

Q: How does mass affect density?

A: Mass is a factor in density, the density is proportional to the mass. So as the mass increases, so does the density, provided the volume remains constant.

Q: How does volume affect density?

A: If an object has a larger mass than its volume it has a high density, if an object has a smaller mass than its volume it has a lower density.

A speedboat moving at 28 m/s approaches a no-wake buoy marker 91 m ahead. The pilot slows the boat with a constant acceleration

Tpy6a [65]

Answer:

7.5 m/s

Explanation:

We can find its velocity when it reaches the buoy by applying one of Newton's equations of motion:

$v^2 = u^2 + 2as$

where v = final velocity

u = initial velocity

a = acceleration

s = distance traveled

From the question:

u = 28 m/s

a = -4 $m/s^2$

s = 91 m

Therefore:

$v^2 = 28^2 + 2 * (-4) * 91\\\\v^2 = 784 + -728 = 56\\\\v = \sqrt{56}\\ \\v = 7.5 m/s$

The velocity of the boat when it reaches the buoy is 7.5 m/s.
