Answer : The mass of a sample of water is, 888.89 grams
Explanation :
Latent heat of vaporization : It is defined as the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.
Formula used :

where,
q = heat = 2000 kJ =
(1 kJ = 1000 J)
L = latent heat of vaporization of water = 
m = mass of sample of water = ?
Now put all the given values in the above formula, we get:

(1 kg = 1000 g)
Therefore, the mass of a sample of water is, 888.89 grams
Answer:
C. 9.9 cm
Explanation:
The location of the object, u = 14 cm
The location of the image, v = 5.8 cm
The focal length of the mirror, f = Required
The mirror formula for a convex mirror is given as follows;

Therefore, we get;

Therefore;

The focal length of the mirror, f ≈ 9.9 cm

Explanation:
Gamma radiations do not reach the surface of the Earth
Explanation:
Sun radiates all of these radiations but one of them does not reach the surface of the Earth. Most of the radiation switch reaching the Earth's surface are visible and infrared radiations.
