Correct Answer: 1 in 20
Correct Answer: stagnation pressure
Correct Answer: representing data in terms of measurable physical quantities.
Explanation:
Analog synthesis uses a mixture of complex sounds that are shaped by filtering. It is based on representing data in terms of measurable physical quantities, in this case sound waves.
Correct Answer: Fathometer
Correct Answer: Weight
Explanation:
We know that,
Weight W = mg. That is mass times gravitational force.
Correct Answer: Kelvin
Explanation:
Kelvin temperature scale is the temperature scale that is based upon absolute zero.
Correct Answer: 3600 joules
Explanation:
The watt-hour (WH) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.
1 WH = 3600 joules.
Correct Answer: 0
Explanation:
If an object moves with some velocity that means the magnitude and direction of the object changes i.e, the object moves with some acceleration. Hence, if the object moves with constant velocity, no change in direction and magnitude of speed i.e, no acceleration = 0 acceleration.
Correct Answer: Zero
Correct Answer: pressure
