Answer:

C. It is caused by flowing negatively charged particles.

Explanation:

Current electricity is caused by flowing negatively charged particles. The negatively charged particles that are responsible for the flow of electricity are called electrons.

The force is equal at all points in the field as the field lines are parallel in a uniform field. So, negatively charged particles will move in the opposite direction to the current.

Hence, the correct answer is "C. It is caused by flowing negatively charged particles."

A sample of a monatomic ideal gas initially at temperature T, undergoes a process during which the pressure of the gas triples a

Allisa [31]

Answer:

B) 8 T.

Explanation:

For an ideal gas , the gas law that it follow is as follows

P₁V₁ / T₁ = P₂ V₂ /T₂

This law is followed by all the gases whether mono atomic or diatomic.

In this case following information are given

P₂ / P₁ = 3

V₂ / V₁ = 3

T₁ = T

T₂ = ?

From the gas law formula given , we have

$T_2 =\frac{P_2\times V_2\times T_1}{P_1\times V_1}$

$V_2 = \frac{P_2}{P_1} \times\frac{V_2}{V_1}\times T$

= 3 X 3 T

= 9 T

Change in temperature = 9T - T = 8 T.

What is the change all living things undergo as the grow

Vladimir [108]

All of the change that living things undergo as they grow is called development. That is the name when the changes are within a single unit and over a period of time as short as a lifetime. When the change occurs over thousands of years then it's called evolution.
