List of top Physics Questions

Cooking food is difficult on hills. The boiling point decreases with increase in pressure.
: Bulk modulus if elasticity (K) represents incompressibility of the material. : Bulk modulus of elasticity is proportional to change in pressure.
Balmer series lies in the visible region of electromagnetic spectrum. $\frac {1}{?}=R \bigg [\frac {1}{2^2}- \frac {1}{n^2} \bigg ],$ where $ n=3,4,5 $
: Atom as a whole is electrically neutral. : Atom contains equal amount of positive and negative charges.
: Angle of deviation depends on the angle of prism. : For thin prism, $\delta = (\mu - 1) A$.
Angle and angular displacement are dimensionless quantities. Angle is equal to arc length divided by radius.
An object may fall with a constant velocity. This happens when acceleration of the object is equal to acceleration due to gravity.
An electric motor converts electrical energy to mechanical energy The working of the motor is based on mutual induction
Water flows faster than honey. The coefficient of viscosity of water is less than honey.
: When hot water is poured in a thick glass tumbler then the tumbler breaks : Glass is a bad conductor of heat
: Stress is restoring force per unit area. : Interatomic forces in solids are responsible for the property of elasticity
Surface tension has same units as force gradient Surface tension is the force gradient along the suiface of liquide
The viscosity of liquid decreuses with rise of temperature. Viscosity of a liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers.
A light body and a heavy body have same momentum. Then they also have same kinetic energy. Kinetic energy does not depend on mass of the body.
: Ductile metals are,used to prepare thin wires. : In, the stress-strain curve of ductile melals, the lenght between the points representing elastic limit and breaking point is very small
At critical temperature, surface tension of a liquid becomes zero. At this tempefature intermolecular forces for liquid and gases become equal. Liquid can expand without any restriction.
Hydrostatic .pressure is a vector quantity. Pressure is force divided by area, and force is a vector quantity.
As the temperature is increased, the time period of a pendulum
As a result of change in the magnetic flux linked to the closed loop shown in figure, an emf, $V$ volt is induced in the loop. The work done (in joule) in taking a charge $q$ coulomb once along the loop is
As the depth of the river increases, the velocity of flow
Arrange 1 light year (ly), 1 astronomical unit (AU) and 1 parallactic second (par sec) in descending order
Arrange 1 slug, 1 chandershekhar limit (CSL) and 1 atomic mass unit (amu) in ascending order.
Angle between the plane of vibration and plane of polarization is
Analogue of mass in rotational motion is
An object is moving towards a concave mirror of length 24 cm. When it is at a distance of 60 cm from the mirror its speed is 9cm/s, the speed of its image at that instantis
