Correct Answer: ampere
Correct Answer: Conductance
Correct Answer: Both A & B
Correct Answer: All of the above
Explanation:
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
Correct Answer: TRUE
Explanation:
The law of conservation of mass states that in any closed system the mass of the system is neither created nor destroyed over time i.e, the mass cannot be changed overtime.
Hence, the given statement is true.
Correct Answer: Weight
Explanation:
We know that,
Weight W = mg. That is mass times gravitational force.
Correct Answer: Fathometer
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: stagnation pressure
Correct Answer: 1 in 20
