 CONFIRMED (تصدیق کی)

Verified (تصدیق کرنا)

Explanation

The correct proverb is: "An open door will tempt a saint."

It means even the most virtuous person may be tempted if given the opportunity.

Explanation

The relative lowering of vapor pressure is given by the formula: 

Relative lowering of vapor pressure = (Mole fraction of solute)/(Mole fraction of solvent + Mole fraction of solute)

Calculating the mole fractions:

Moles of glucose = (18 g / 180 g/mol) = 0.1 mol 

Moles of water = (90 g / 18 g/mol) = 5 mol

Mole fraction of glucose = 0.1 / (0.1 + 5) = 0.02 

Mole fraction of water = 1 - 0.02 = 0.98 

Substituting into the formula:

Relative lowering of vapor pressure = 0.02 / (0.02 + 0.98) = 0.02 / 1 = 0.02 

Therefore, the relative lowering of vapor pressure is 0.02, which is equivalent to 1/50. 

Explanation

You cannot go out because it’s raining very hard.

آپ باہر نہیں جا سکتے کیونکہ بارش بہت سخت ہو رہی ہے۔

The sentence explains why you cannot go out right now, so we need a verb that shows a present continuous action.

“It’s raining” = It is raining → Present continuous tense

It matches the context of an action happening right now.

Explanation

Urea fertilizer contains 46% nitrogen (N).

Urea is a white crystalline solid that is widely used as a fertilizer and animal feed additive.

Explanation

Relative atomic mass is measured by comparing an atom's mass to 1/12th the mass of a carbon-12 atom.

Carbon-12 is the standard reference in modern atomic mass scale.

Explanation

The theory that all living cells are of common origin is attributed to August Weismann. 

Explanation

The least distance of distinct vision for a normal human eye is 25 cm.

This means that when an object is placed at a distance of 25 cm or more from the eye, a clear and distinct image is formed on the retina. 

Explanation

In C, 9 and 4 are integers, so 9 / 4 = 2 (integer division, fractional part is discarded).

Then, 2 * 2 = 4

Explanation

Fringe spacing in a double-slit experiment increases when using light with a longer wavelength.

Therefore, red light will produce the largest fringe spacing compared to blue, green, or yellow light.
