What do an electron and a neutron have in common? Each particle has a mass of 1 amu.
Each particle exists inside an atom.
Each particle has an electrical charge.
Each particle is located in the nucleus.

Answers

The correct answer to this question is B) Each particle exists inside an atom.

EXPLANATION:

Before going to answer this question , first we have to understand the nature of electron and neutron.

Electrons and neutrons are the subatomic particles which are present inside the atom.

Electron is that subatomic particle which is present in the extra nuclear part of the atom, and it moves around the nucleus in different permitted, stationary orbits. The charge of electron is negative.

The neutron is that subatomic particle which is present in the nuclear part of the atom along with protons. The charge of proton is positive and the neutron is neutral in nature.

Hence, the correct option of this question is that both electrons and neutrons are present inside the atom.

Which term defines the process of a wave bending as it enters a new medium?A. reflection
B. refraction
C. destructive bending
D. constructive bending

Answers

The term that defines the process of a wave bending as it enters a new medium is called B. REFRACTION

Refraction is the bending of a wave when it enters a medium where its speed is different. This phenomenon is explained by the conservation of energy and conservation of momentum.

Law of Conservation of energy states the total energy of an isolated system remains constant.

law of conservation of momentum states that in a closed system the total momentum is constant.

In refraction, when a medium changes, the phase velocity also changes but its frequency does not; it remains constant.



Vitellium (Vi) has the following composition:Vi-188: 187.9122 amu; 10.861%Vi-191: 190.9047 amu; 12.428%Vi-193: 192.8938 amu; 76.711%Based on this data, what can you predict about the average atomic mass of vitellium?

Answers

(0.10861 x 187.9122) + (0.12428 x 190.9407)
+ (0.76711 x 192.8938) = 192.1100 amu

In february a little town received snow on a daily basis. The first day they had 10 inches, 3 inches the second, 7 inches the 3rd, and 4 inches on the fourth day. What was the average snowfall?

Answers

The average snowfall of the four days was 6 inches.

What is snow?

When atmospheric water vapor freeze into small ice crystals and falling in small white flakes or lying on the ground as a white layer, it is called snow.

In the question it is said that,

Amount of snow received by the town on first day = 10 inches.

Amount of snow received by the town on second day = 3 inches.

Amount of snow received by the town on third day = 7 inches.

Amount of snow received by the town on fourth day = 4 inches.

Total amount of snow received by the town on these four days = ( 10 + 3+ 7 + 4) inches.

=24 inches.

Hence, average amount of snow received by the town on these four days = total amount of snow received ÷ 4

= ( 24 ÷ 4) inches.

= 6 inches.

Hence, the average snow received by the little town was 6 inches on those days.

Answer:

The average is 6

Explanation:

To find the average, you have to first add all the numbers. After you add all the numbers up, then you divide by how many numbers there are. This one had 4 numbers so you divide by 4
