Air is said to be saturated when it contains the maximum content of water vapour.

The side view mirror, in all the vehicles we use only convex mirror. This mirror makes the objects and small to show them in the mirror. That's why in all such mirrors, "Ojects in the mirror are closer than they appear."

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

Hooke's law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body.Hooke’s law is valid only in the linear part of stress-strain curve. Hence, statement 1 is correct.

General purpose gloves - utility gloves are recommended for cleaning procedures, such as handling soiled linens or decontaminating care areas. Utility gloves are more tear and puncture resistant than other gloves.

Pressure = (Net Force) / (Applied area) = Newton / square meters

Measuring units of pressure are:

. Pascal
. Bar
. Torr
. Pounds per square inch (psi)
. Standard atmosphere (atm).

Yes, the given statement that water is more dense than cooking oil is TRUE as water more denser than oil it is sinked when it is poured in oil.
