Answer 1

Turbulence causes formation of eddies and this causes energy loss.
High Reynold's Number implies high inertial forces with low viscous forces. This causes high turbulence.

Answer 2

Turbulence causes formation of eddies and this causes energy loss.

High Reynold's Number implies high inertial forces with low viscous forces. This causes high turbulence.

Turbulence is always dissipative.

High reynold number promotes turbulence.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Assertion is correct but Reason is incorrect.

Two drops of the same radius are falling through air with a steady velocity of $5 cm per sec .$ If the two drops coalesce, the terminal velocity would be

The mass of a lead ball is M. It falls down in a viscous liquid with terminal velocity V. The terminal velocity of another lead ball of mass 8M in the same liquid will be:

A spherical ball falls through viscous medium with terminal velocity $v$ . If this ball is replaced by another ball of the same mass but half the radius, then the terminal velocity will be (neglect the effect of buoyancy)

An object from a greater height reaches a steady terminal velocity.

The viscous forces on a body depends upon its velocity. The greater the velocity the greater is the viscous force.

A metal ball of radius 1mm and density 104kg m−3. falls freely in air through a height 'h' before falling in a tank full of water. If on falling in water its velocity remains unchanged, then the value of h will be (Coefficient of viscosity of water =10−3 Pa.s and g=10ms−2)
