A particle is moving in a circular path of radius r . The displacement after half a circle would be

Answers

Answer:

Explanation:

As we know that

The displacement is the total distance measured between the initial or start and final or destination point

If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point

We attached the diagram for better understanding

As per the diagram.

The displacement after half-circle is

AB = OA + OB

= r + r

= 2r

Mrs. Patil travels from her home to work in 0.25 hours. The direct distance between her home and work is 8.0 miles. If Mrs. Patil travels 12.4 miles from home to her job, what is her average velocity during the trip?

Answers

Regardless of the path taken, at the end of the trip Mrs. Patil will be 8.0 miles away from home. If the path taken involves a trip lasts 0.25 hours, then the average velocity over the trip is

$\frac{8.0\,\mathrm{mi}}{0.25\,\mathrm h}=32\,\frac{\mathrm{mi}}{\mathrm h}$

What type of soil can become as hard as stone when dries out

Answers

maybe clay soil.............................

I dont think there is such type of soil. Soil is formed by weathering of rocks and held together by loose force. When any type of soil dries out, it becomes brittle. Thus, there is no such type of soil. yes, it can be clayey because it has higher density, but it does not become as hard as a ROCK when it dries out actually.

Why are most cells 70 percent water?

Answers

Cells are the units that together make the organism. Most of the cells are 70% water as it is the most abundant molecule that makes the cytoplasm and organelles.

What is a cell?

A cell is a structural organization that is composed of various organic, and inorganic substances that also have water as the most abundant molecule. It is the most important component that is needed for cellular and metabolic reactions.

It makes the cytoplasm of the cell that occupies most of the cell portion. Water is the most important reactant and the product of the photosynthesis and respiration processes of plant and animal cells. Water is needed by the cell to transport the nutrients and the waste, and even in cell signaling.

Therefore, cells are made of 70% water as the component.
