Gre4nikov [31]3 years ago
4 0

Answer:

Explanation:

in all the question we have to use same technique

in 1 question

weight/force exerted by dorje(F)=1500N

total surface area of sole(A)=0.5m²

we know that,

   P=\frac{F}{A}

or, p=\frac{1500}{0.5}

∴ P=3000pa

in question 2nd

pressure(P)=40 pa

force exerted by block(F)=80N

we know,

pressure(P)=\frac{Force(F)}{Area(a)}

   area=\frac{80}{40}

∴area =2m

ow you can do other by yourself

High concentrations of solutes such as sugar or salt results in plasmolysis of cells due to the onset of which phenomenon. Selec
malfutka [58]

Answer:

The correct answer will be option-B

Explanation:

Three types of solution are formed based on the concentration of the solute which are:

1. High solute concentration- Hypertonic solution

2. Low solute concentration- Hypotonic solution

3. Equal solute concentration- Isotonic solution

When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.

If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.

Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.
