Physics Easy

Which process transfers heat through the movement of fluid currents?

  • AConvection
  • BConduction
  • CRadiation
  • DSublimation
Permalink
Correct Answer: Option A — Convection
Explanation: Convection transfers heat through the movement of fluids as warmer less dense fluid rises and cooler denser fluid sinks creating convection currents that distribute thermal energy.

What is the phenomenon of resonance in physics?

  • AIncrease in amplitude when driving frequency matches natural frequency
  • BDecrease in amplitude of oscillations over time
  • CThe bending of waves around obstacles
  • DSplitting of white light into colours
Permalink
Correct Answer: Option A — Increase in amplitude when driving frequency matches natural frequency
Explanation: Resonance occurs when a system is driven at its natural frequency causing the amplitude of oscillations to increase dramatically and can be seen in musical instruments and bridges.

Which type of mirror is used in reflecting telescopes?

  • APlane mirror
  • BParabolic concave mirror
  • CConvex mirror
  • DCylindrical mirror
Permalink
Correct Answer: Option B — Parabolic concave mirror
Explanation: Reflecting telescopes use parabolic concave mirrors to collect and focus parallel rays of light from distant stars to a single focal point without chromatic aberration.

Physics Medium

Which phenomenon explains why objects appear to weigh less when submerged in water?

  • ASurface tension
  • BBuoyancy
  • CCohesion
  • DAdhesion
Permalink
Correct Answer: Option B — Buoyancy
Explanation: Buoyancy is the upward force exerted by a fluid on a submerged object equal to the weight of fluid displaced making objects appear lighter as described by Archimedes' Principle.

Physics Easy

What is the SI unit of pressure?

  • ANewton
  • BJoule
  • CPascal
  • DWatt
Permalink
Correct Answer: Option C — Pascal
Explanation: The Pascal is the SI unit of pressure named after Blaise Pascal and defined as one Newton of force per square metre of area.

What is the working principle of a hydraulic press?

  • APascal's law
  • BArchimedes' principle
  • CBernoulli's principle
  • DNewton's third law
Permalink
Correct Answer: Option A — Pascal's law
Explanation: A hydraulic press works on Pascal's Law where pressure applied to an enclosed fluid is transmitted equally in all directions allowing a small force to generate a much larger force.

Physics Hard

Which effect causes the apparent change in frequency of light from a moving star?

  • APhotoelectric effect
  • BCompton effect
  • CZeeman effect
  • DDoppler effect
Permalink
Correct Answer: Option D — Doppler effect
Explanation: The Doppler effect causes light from a star moving away from us to shift to longer wavelengths called red shift while light from an approaching star shifts to shorter wavelengths called blue shift.

Physics Medium

What is the relationship between work done and force in the direction of displacement?

  • AWork equals force times displacement
  • BWork equals force plus displacement
  • CWork equals force times time
  • DWork equals force divided by displacement
Permalink
Correct Answer: Option A — Work equals force times displacement
Explanation: Work done is defined as the force applied multiplied by the displacement in the direction of that force expressed as W equals Fd where both force and displacement must be in the same direction.

Physics Medium

Which type of energy is stored in a compressed spring?

  • AKinetic energy
  • BThermal energy
  • CElastic potential energy
  • DChemical energy
Permalink
Correct Answer: Option C — Elastic potential energy
Explanation: A compressed spring stores elastic potential energy due to the deformation of its molecular structure and this energy is released as kinetic energy when the spring is allowed to expand.

Physics Medium

What is meant by the term inertia in physics?

  • AThe tendency of an object to resist changes in its state of motion
  • BThe tendency of an object to accelerate
  • CThe force of gravity on an object
  • DThe energy stored in a moving object
Permalink
Correct Answer: Option A — The tendency of an object to resist changes in its state of motion
Explanation: Inertia is the property of matter by which an object resists changes to its state of rest or uniform motion in a straight line as described by Newton's First Law.
