Why is the pressure 101.3kPa significant
nydimaria [60]

Answer:

Explanation:

The kPa-kilopascal is the unit of pressure. It was named after Blaise Pascal, a mathematician and physicist.

The kPa is 1000Pa. Kilo stands for 1000. Now what is a pascal?

A pascal is the amount of force(Newton) exerted per unit area.

            1Pa = 1Nm⁻²

At the standard atmospheric level, the pressure is 101.325 x 10³ Nm⁻² i.e the atmosphere exerts a pressure of 101.325 x 10³N in an area of a body.

This unit is used to calculate pressure. It can be converted to other units.

skelet666 [1.2K]

Answer:

less than 5 centimeters because it is a nonvascular plant

Explanation:

Mosses are a group of plants under the division Bryophyta. They are said to be the most primitive plant life in existence as they lack true roots, stems and leaves. They also lack vascular system, hence, they are regarded as non-vascular plants. They usually grow in very small sizes (about 0.2 - 10cm).

According to this question, Penny bought a club moss plant for her water garden and needs to know how tall the plant will grow so she know how much space it will need. Since it is a miss plant that lacks vascular tissues i.e. nonvascular, it will likely grow less than 5 centimeters in height.
