If a man has a mass of 83 kilograms on Earth, what will the force of gravity on his body be on the moon?
VladimirAG [237]
The answer is (A.) 135.6 N

————

Here is the formula you will need to answer the question.

Formula:
Force(N) = Mass(kg) x Acceleration(m/s²)
or... F(N) = m(kg) x a(m/s²)

————

We need to be certain of the information presented. The problem says the man has a "Mass" of 83 kilograms on Earth. If a man has a Mass of 83 kilograms on Earth, he has a mass of 83 kilograms everywhere. The mass for this problem (even on the moon) is 83.

Mass(kg): 83

————

To find the acceleration of object on other planets, moons, ect, you'll need to search the internet or ask a teacher. There are ways to calculate this, but the problem didn't supply the necessary information to do so.

Acceleration: 1.625 m/s²

————

Now just plug the information into the formula.

F(N) = m(kg) x a(m/s²)

N = 83 x 1.625
N= 135.875

When considering that there could be a slighty more accurate number for acceleration, it can be concluded that the best answer is (A.)

During a sunset, molecules interact with light and scatter all but which colors?
sergey [27]

Answer:

B.red

Explanation:

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the decreasing wavelength the spectrum are:  

Red , Orange, Yellow, Green, Blue, Indigo, Violet

Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.

Also, Violet light gets scattered the most while the red light gets scattered the least.

During the time of the sunset, the Earth is rotating away from the Sun. Thus, most of the light colors scatters in the ways and the color that least scatter which is red reaches the Earth.

That's why, at the time of sunrise and sunset, the sky looks red.

What volume (in L) of oxygen will be required to produce 77.4 L of water vapor in the reaction below?
Nostrana [21]

Answer:

For the production of 77.4 L water 90.3 L oxygen is required.

Explanation:

Given data:

Volume of oxygen required = ?

Volume of water produced = 77.4 L

Solution:

Chemical reaction equation:

2C₂H₆ + 7O₂  →  4CO₂ + 6H₂O

1 mole = 22.414 L

There are 6 moles of water = 6×22.414 = 134.5 L

There are 7 moles of oxygen = 7×22.414 = 156.9 L

Now we will compare the litters of water and oxygen:

                              H₂O           :              O₂    

                              134.5         :              156.9

                                77.4         :             156.9/134.5×77.4 =90.3 L

So for the production of 77.4 L water 90.3 L oxygen is required.
