Correct Answer: Crescendo
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: 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: 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: 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.
Correct Answer: Gravitational forces
Correct Answer: Sand
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.
Correct Answer: Lactometer - Specific gravity of liquids
Correct Answer: ohm
