General Physics

A nuclear reaction must be balanced in terms of

a) Mass and volume
b) Energy and weight
c) Number of electrons
d) Mass and energy

✔Answer

✔Solution

Correct Answer Is : Mass and energy

Solution Is : A nuclear reaction must be balanced in term of mass energy. The mass number and total energy before the reaction must equal the total energy after the reaction

A watch spring when wound up acquires

a) Mechanical energy
b) Kinetic energy
c) Potential energy
d) Light energy

✔Answer

✔Solution

Correct Answer Is : Potential energy

Solution Is : A watch spring when wound up acquires potential energy

When water freezes its density

a) Decreases
b) Increases
c) Become zero
d) Remains constant

✔Answer

✔Solution

Correct Answer Is : Decreases

Solution Is : Water at ordinary temperatures contract and increases in density as it cooled like most substance. But at about 4?C, it reaches a maximum density and then decreases in density as it approaches the freezing point.

Which one of the following is a non-dimensional quantity ?

a) Strain
b) Co-efficient of viscosity
c) Gas constant
d) Plank`s constant

✔Answer

✔Solution

Correct Answer Is : Strain

Solution Is : Strain is a non-dimensional quantity.

The density of water is greater than the density of kerosene. If the two are mixed

a) Kerosene dissolves in water
b) They mix uniformly
c) Water floats on kerosene
d) Kerosene floats on water

✔Answer

✔Solution

Correct Answer Is : Kerosene floats on water

Solution Is : The density of kerosene oil is less than density of water. Hence it floats on top of the water layer

The cloud float in the atmosphere because of their low

a) Temperature
b) Velocity
c) Pressure
d) Density

✔Answer

✔Solution

Correct Answer Is : Temperature

Solution Is : The cloud float in the atmosphere because of their low temperature

The change of a solid into vapour directly is called

a) Vaporization
b) Freezing
c) Melting
d) Sublimation

✔Answer

✔Solution

Correct Answer Is : Sublimation

Solution Is : The change of a solid into vapour directly is called sublimation

The audible frequency range of a human ear is

a) 20 Hz to 200 Hz
b) 2 Hz to 20 Hz
c) 200 Hz to 2000 Hz
d) 20 Hz to 20000 Hz

✔Answer

✔Solution

Correct Answer Is : 20 Hz to 20000 Hz

Solution Is : The audible frequency range of a human ear is 20 Hz to 20000 Hz

The wavelength of X-rays is of the order of

a) 1 mm
b) 1 cm
c) 1 micron
d) 1 angstrom

✔Answer

✔Solution

Correct Answer Is : 1 angstrom
