Interference interaction of sound waves causes beats.

Answer: Option A

<u>Explanation:</u>

When two sound waves interact with each other, a new wave is produced which is due to the interference between the sound waves. Beats are produced due to interference in sound waves where waves might be of different frequency but of same amplitude.

There are two types of interference called as constructive and destructive interference depending upon either the resultant amplitude is smaller or larger.

Complete the sentences below using the words below, you may use each word more than once

Decreases, stays the same, increases. The volume decreases because as air is cooled, the individual molecules collectively possess less kinetic energy and the distances between them decrease, thus leading to a decrease in the volume they occupy at a certain pressure (please note that my answer only holds under constant pressure; air, as a gas, doesn't actually have a definite volume). The mass stays the same because physical processes do not create or destroy matter. The law of conservation of mass is obeyed. You're only cooling the air, not adding more air molecules. The density decreases because as the volume decreases and mass stays the same, you have the same mass occupying a smaller volume. Density is mass divided by volume, so as mass is held constant and volume decreases, density increases.

A student draws a picture of the products and reactants of a chemical reaction. What, if anything, is wrong with the drawing?
ASHA 777 [7]

The complete question is: A student draws a picture of the products and reactants of a chemical reaction. What, if anything, is wrong with the drawing?

A) The drawing is wrong because there are more chemicals on the products side.

B) The drawing is correct because there are 12 compounds on each side of the arrow.

C) The drawing is wrong because there are different compounds on each side of the arrow.

D) The drawing is correct because there are 12 atoms of each type on each side of the arrow.

Answer:

Option D is correct

Explanation:

In the diagram attached below, it can be seen that there are 12 atoms of element which combine with 12 atoms of another element forming a compound. For the drawing to be correct, there should be 12 atoms of each type of element on both the reactants as well as product side, which is the case. There cannot be imbalance in the number of atoms of different elements on the two sides for a chemical reaction to occur.

Hence, option D is correct.

All music, _______ in the world, is from only ______ notes.​
AnnZ [28]

Answer:

All music in the world, is form only two notes and those notes are described below in detailed explanation.

What is the average electric current in a wire, when a charge of 150 C passes in 30 s?
NARA [144]
We know, I = Q / t
Here, Q = 150 C
t = 30 s

Substitute their values, 
I = 150 / 30
I = 5 A

In short, Your Answer would be 5 Ampere

Hope this helps!
