- Question
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
- Correct Answer
- be traveling at a speed that is faster than perceived
ExplanationVelocitation 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.

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.
Correct Answer: gravitational pull
Explanation:
The atmospheric pressure at the surface of the Earth is due to gravitational pull of the earth and is about 14.7 psi.
That means that the weight of a column of air which has a cross section of 1 square inch and which stretches from the surface of the Earth to space is 14.7 pounds.
Correct Answer: All the above
Explanation:
Metamorphism is the change of minerals or geologic texture in pre-existing rocks, without the protolith melting into liquid magma. The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids.
The parent rock must be in solid form. Tons of pressure must be applied for metamorphism to happen. The process must take place underground.
Correct Answer: 1 TB
Explanation:
1 TB > 1 GB > 1 MB > 1 KB
1 Tb (Tera Byte) = 1024 GB
1 GB (Giga Byte) = 1024 MB
1 MB (Mega Byte) = 1024 KB
1 KB (Kilo Byte) = 1024 Bytes
1 Byte = 8 Bit
Hence, largest unit of information is TB (Tera Byte) and smallest unit of information is Bit.
Correct Answer: Evaporation
Explanation:
Evaporation is the process that allows water to enter into the atmosphere.
Sunlight turns liquid water into water vapor which then rises higher into the atmosphere and forms into clouds.
Plants, too, help water get into the atmosphere through a process called transpiration.
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.
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.
Correct Answer: Inertia of motion
Explanation:
When a running car stops suddenly, the passengers tends to lean forward because of Inertia of motion.
Correct Answer: Crescendo
Correct Answer: Poles
Explanation:
Gravitational force is the force that binds everything at the surface of the earth. Gravitational force is maximum at Poles.
