591.
Velocity of efflux can be found by using?
Correct Answer: B. Torricelli's theorem
One-liner
The velocity of efflux is found by using Torricelli's theorem, which states that the speed of a fluid flowing out of an orifice is equal to that of a freely falling body from the same height.
592.
A _ is an object with at least one slanting side ending in a sharp edge, which cuts material apart.
Correct Answer: B. Wedge
One-liner
A wedge is a simple machine with at least one slanting side ending in a sharp edge, used to cut or split materials apart.
593.
The particles of a liquid?

One-liner
The particles of a liquid are free to move in a container but remain in close contact with one another.
594.
The splitting of a heavy nucleus into smaller nuclei is called?
Correct Answer: C. Fission
One-liner
The splitting of a heavy nucleus into smaller nuclei is called fission.
595.
In spur gear, the shaft is to the gear.
Correct Answer: B. Parallel
One-liner
In a spur gear, the shaft is parallel to the gear.
596.
Rate of diffusion is the fastest in?
Correct Answer: C. Gases
One-liner
Rate of diffusion is the fastest in gases because gas particles have the highest kinetic energy and move most freely.
597.
When an observer moves with the velocity of light relative to a timing device at rest, he would notice:
Correct Answer: D. Infinite time
One-liner
When an observer moves at the velocity of light relative to a stationary timing device, he would notice infinite time — this is a consequence of time dilation in Einstein's special theory of relativity.
598.
Water striders can adhere on the surface of water due to which property of water?
Correct Answer: A. Surface tension
One-liner
Water striders walk on water due to surface tension, the cohesive force that makes the water surface behave like a stretched elastic membrane.
599.
_ is the term used for all liquids and gases.
Correct Answer: B. Fluid
One-liner
The term used for all liquids and gases is Fluid.
600.
A is an inclined plane wrapped around a cylinder, used to fasten objects.
Correct Answer: A. Screw
One-liner
