I think the earth because it has more mass than the moon

and the reason is because the earth is bigger than the moon so it has a bigger chance that earth has a higher surface temperature

I took the FLVS test earlier; Part One and Part Two:

Earth has a lower average temperature than the moon. Although, some might think that the earth has a higher average temperature because the earth is hot. Yet, the moon has far more avaerage temperature than the earth because the earths atmosphere blocks the suns radiation from directly hiting it. Also, the moon doesn't have a atmosphere to keep away the suns radiation.

Which steps can you take to help a person suffering from achohol abuse?

alexandr1967 [171]

Answer:

Call a treatment service. Seek out a healthcare professional. Lastly, report the issue to the local authorities.

Why did I choose these?

You call the treatment services to take care of the person.

You seek out a healthcare professional to get him/her back in shape.

Then you report the issue so that nobody will be endangered by the person that is abusing alcohol. Many accidents occur because of this and that is why you report it.

By what factor is the intensity of sound at a rock concert louder than that of a whisper when the two intensity levels are 120 d

lyudmila [28]

Answer:

d) $7.94\times 10^{9}$

Explanation:

β₁ = sound level of sound at rock concert = 120 dB

β₂ = sound level of sound due to whisper = 21 dB

I₁ = Intensity of sound at rock concert

I₂ = Intensity of sound due to whisper

sound level of sound at rock concert is given as

$\beta _{1} = 10 log\left ( \frac{I_{1}}{10^{-12}} \right )$

$120 = 10 log\left ( \frac{I_{1}}{10^{-12}} \right )$

$12 = log\left ( \frac{I_{1}}{10^{-12}} \right )$ Eq-1

sound level due to whisper is given as

$\beta _{2} = 10 log\left ( \frac{I_{2}}{10^{-12}} \right )$

$21 = 10 log\left ( \frac{I_{2}}{10^{-12}} \right )$

$2.1 = log\left ( \frac{I_{2}}{10^{-12}} \right )$ Eq-2

subtracting Eq-2 from Eq-1

$12 - 2.1 = log\left ( \frac{I_{1}}{10^{-12}} \right ) - log\left ( \frac{I_{2}}{10^{-12}} \right )$

$9.9 = log\left ( \frac{I_{1}}{I_{2}} \right )$

$\left ( \frac{I_{1}}{I_{2}} \right ) = 7.94\times 10^{9}$

A freight train leaves the train station 4hrs before a passenger train. The two trains are traveling in the same direction on pa

enot [183]

It can be said that most of the required information's are already given in the question.
Let us assume the speed of the passenger train = x
Speed of the freight train = y
x = y + 40
The second equation will be
6 * x = 10 * y
6x = 10y
Dividing both sides by 2, we get
3x = 5y
x = 5y/3
Putting the value of "x" in the first equation, we get
x = y + 40
5y/3 = y + 40
5y = 3y + 120
5y - 3y = 120
2y = 120
y = 60 mph
Putting the value of y in the first equation, we get
x = y + 40
= 60 + 40
= 100 mph
From the above deduction, we can conclude that the passenger train is traveling at 100 mph and the freight train is traveling at 60 mph.
