Physics Quiz Questions help in the preparation for various competitive exams.

1- A pond with crystal-clear water appears shallower than it is. This is due to
(A) Reflection
(B) Refraction
(C) The transparency of water
(D) Dispersion

2-A lunar eclipse occurs when
(A) Earth comes between the Sun and the Moon
(B) Sun, Moon and Earth are not in the same line
(C) Sun comes between the Earth and the Moon
(D) Moon comes between the Sun and the Earth

3-When a ship travels from West to East over the International Date Line
(A) It gains half a day
(B) It loses half a day
(C) It gains one day
(D) It losses one day

4- How much noise does a person breathe out?

(A) 0.1 Decimal
(B) 35 Decimal
(C) 10 Decimal
(D) 0.5 Decimal

5-It takes a lot longer to cook food in the hills than it does in the plains because
(A) In the hills the atmospheric density is low and therefore a lot of heat is lost to the atmosphere
(B) Due to low atmospheric pressure on the hills, the water boils at a temperature higher than 100°C and therefore water takes longer to boil
(C) In the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100°C causing an increase in cooking time
(D) In the hills the humidity is high and therefore a lot of heat is absorbed by the atmosphere leaving very little heat for cooking

(C) High voltage to low voltage
(D) Low voltage to high voltage

7-Stars appears to move from east to west because
(A) The earth rotates from west to east
(B) All stars move from east to west
(C) The background of the stars moves from west to east
(D) The earth rotates from east to west

8- An element’s isotopes contain
(A)The same number of neutrons but a different number of protons
(B) The same number of protons but a different number of neutrons
(C) Equal number of nucleons
(D) Equal number of protons and electrons
