Goshia [24]3 years ago
5 0

Answer: Option (A) is the correct answer.

Explanation:

Potential energy is defined as the energy obtained by an object due to its position or height.

Mathematically,         P.E. = mgh

where         m = mass of object

                   g = force of gravity

                   h = height of the object

Hence, we can conclude that out of the given options the best example of potential energy holding a basketball in the air.

In the following reaction, how many liters of carbon dioxide will be produced if 250 liters of oxygen is used in the combustion
love history [14]
The balanced reaction would be:<span>

C12H22O11 + 12O2 = 12CO2 + 11H2O

We are given the amount of oxygen used in the combustion. This will be the starting point of our calculation. We use the ideal gas equation to find for the number of moles.

n = PV / RT = 1.00(250 L) / (0.08206 atm L/mol K ) 273 K
n= 11.16 mol O2

</span>11.16 mol O2<span> (12 mol CO2 / 12 mol O2) = 11.16 mol CO2

V = nRT/P =</span>11.16 mol CO2<span> x 273 K x 0.08206 atm L/mol K / 1 atm
V=250 L</span>

Which of the following is not a characteristic of electromagnetic waves
Mekhanik [1.2K]

<u>Complete Question:</u>

Which of the following is not a characteristic of electromagnetic waves?

a. they can travel through a vacuum.

b. they can travel at various speeds through any one material.

c. they can be refracted.

d. they can be reflected.

<u>Correct Option:</u>

"They can travel at various speeds through any one material" is not a characteristic of electromagnetic waves.

<u>Explanation:</u>

It is a form of energy generated by interference from the oscillating magnetic and electric recorded. So we may conclude that it is created by moving electric charged particles through the vacuum so matter. This is a wave in which the two vectors vibrate each other perpendicularly and in the direction of the wave. Electromagnetic waves which involve gamma-rays, x-rays, ultraviolet rays, infrared-rays, microwaves and radio-waves can be featured by:

  • They may pass through the vacuum.
  • They are allowed to move through the matter and are reflectable.
  • They can pass through all of the material at the same pace. This means there is still constant speed of light, which is, they can be refracted.
