Physics problems
- 1. The energy associated with motion is called
Options- A. Potential energy
- B. Kinetic energy
- C. Both A & B
- D. None of the above Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: Kinetic energy
Explanation:
Energy can be either a potential energy or a kinetic energy.
The energy associated with motion is called Kinetic energy and it can be stored. And the energy associated with position is called Potential energyand it cannot be stored.
- 2. Velocitation is the tendency to
Options- A. be traveling at a speed that is faster than perceived
- B. be traveling at a speed that is slower than perceived
- C. Both A & B
- D. None of the above Also asked in: GATE, CAT, Bank Exams, AIEEE, Bank PO, Bank Clerk, Analyst
Correct Answer: be traveling at a speed that is faster than perceived
Explanation:
Velocitation is a phenomenon caused by driving for long periods at high speeds. A driver may experience velocitation when coming off of the highway; the change in speed makes him or her think that the car is going much slower than it actually is.
Velocitation is the tendency to be traveling at a speed that is faster than perceived.
- 3. Electric power is measured in units of
Options- A. Volt
- B. Joule
- C. Watt
- D. Ampere Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: Watt
Explanation:
Electric power is the rate per unit time, at which electrical energy is transferred by an electric circuit. The power of electricity is measured in watts and kilo watts.
1 Watt is the unit of electrical power equal to one ampere under the pressure of one volt.
- 4. Refractive Index of glass with respect to water is
Options- A. 4/3
- B. 9/8
- C. 2/3
- D. 8/9 Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: 8/9
Explanation:
Refractive Index of glass with respect to water can be calculated by
(Refractive Index of glass with respect to air) × (1/Refractive Index of water with respect to air)
We know that,
Refractive Index of glass with respect to air = 4/3
Refractive index of water with respect to air = 3/2
Hence, Refractive Index of glass with respect to water = (4/3) x (2/3) = 8/9.
- 5. When a running car stops suddenly, the passengers tends to lean forward because of
Options- A. Gravitational force
- B. Inertia of motion
- C. Law of conservation of mass
- D. Both B & C Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: Inertia of motion
Explanation:
When a running car stops suddenly, the passengers tends to lean forward because of Inertia of motion.
- 6. A gradual increase in loudness is known as
Options- A. Crescendo
- B. Timbre
- C. Fortissimo
- D. None of the above Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: Crescendo
- 7. Gravitational force is maximum at which place
Options- A. Poles
- B. Tropic of cancer
- C. Tropic of capricorn
- D. Equator Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: Poles
Explanation:
Gravitational force is the force that binds everything at the surface of the earth. Gravitational force is maximum at Poles.
- 8. Stars are held together by
Options- A. Gravitational forces
- B. Electrical forces
- C. Ionic forces
- D. Magnetic forces Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO, IT Trainer
Correct Answer: Gravitational forces
- 9. Glass is made of which material?
Options- A. Calcium carbonate
- B. Sand
- C. Silver Iodide
- D. Lime Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: Sand
- 10. When a barometer is rising air pressure is
Options- A. increasing
- B. decreasing
- C. constant
- D. zero Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: increasing
Explanation:
The device which is used to measure air pressure is called as barometer. If the barometer reading is rising, it indicates that the air pressure is increasing and if the reading is falling the air pressure is decreaing.
