Answer: A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

If there are 3 resistors of .5 ohms, 1 ohms, and 1 ohms connected in parallel then what is the equivalent resistance

Ede4ka [16]

Answer:0.45ohms

Explanation:

Let R be there equivalent resistance

1/R=1/r+1/r+1/r

1/R=1/5+1/1+1/1

1/R=1/5+2

1/R=(1+10)/5

1/R=11/5

Cross multiplying we get

11R=5

Divide both sides by 11

11R ➗ 11=5 ➗ 11

R=0.45ohms

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture? A) The te

VikaD [51]

Answer: Option (A) is the correct answer.

Explanation:

Relation between kinetic energy and temperature is as follows.

$K.E \propto \frac{3}{2}kT$

As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.

And, when gas particles move slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.

Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
