The average velocity of molecules of nitrogen gas (N2) at room temperature is around 500 m/s. If you were to raise the temperatu

DIA [1.3K]

Answer:

C

Explanation:

The speed of a molecule is directly related to its kinetic energy, which is directly related to the temperature. As the temperature increases, so does a molecule's speed. Of the options provided, only option C has a higher speed than 500m/s.

A bucket of water with mass 5 kg sits on the ground with a coefficient of static friction of 0.35. What is the maximum force of

allochka39001 [22]

Answer:

The force of static friction is 17.15 N

Explanation:

It is given that,

Mass of the bucket, m = 5 kg

The coefficient of static friction is, $\mu=0.35$

We need to find the maximum force of static friction. It is given by :

$F=\mu mg$

$F=0.35\times 5\ kg\times 9.8\ m/s^2$

F = 17.15 N

So, the force of static friction is 17.15 N. Hence, this is the required solution.

When placed in a ________ solution, a cell will exhibit a net loss of water. the specific process by which the water leaves the

katen-ka-za [31]

The specific process by which the water leaves the cell is called plasmolysis.

<h3>What is plasmolysis?</h3>

Plasmolysis is the process in which the cell loses the water that is present inside it because the environment of the cells produces pressure to build up inside the cell. If a cell is present in a hypertonic solution means that solvent concentration is lower in the surrounding solution, then water comes out of the cell while on the other hand, if a cell is present in a hypotonic solution in which the solvent concentration is higher in the surrounding solution, then water goes inside of the cell. The movement of liquid inside or outside of the cell occurs due to the semi-permeable membrane of the cell.

So we can conclude that the specific process by which the water leaves the cell is called plasmolysis.

What are the assumptions on which the cosmological principle is based?.

prisoha [69]

Homogeneity and isotropy, On large enough scales, the Universe looks pretty much the same in all directions. The big bang theory is based on two assumptions: the first is centered around Einstein's general theory of relativity, which accurately describes gravity and the interactions of matter; and the second, also known as the cosmological principle, asserts that the universe is homogeneous and isotropic on a large enough scale.
