4.Which is the correct explanation of the difference between Laminar and Turbulent flow?

Laminar flow has complex streamlines, and Turbulent flow has very simple streamlines.

Laminar flow is an orderly flow, and Turbulent flow is a disorderly flow.

Laminar flow is inertia dominated, and Turbulent flow is viscous

dominated.

5.What is the Zeroth Law of Thermodynamics?

The ocean being a large body of water will have thermal equilibrium.

This means it will take time for the solar energy to affect the ocean and

change its temperature.

Moves from one medium to another and can travel through water or air.

The total energy of an isolated system is constant.

Two objects in thermal equilibrium with a third object are in

thermal equilibrium with each other.

Answer 1

1) Convection heat systems are of two types, forced convection type and free convection type

2) not sure about this one but lithography is used to draw patterns on pcbs and other parts

3) Electron microscopes are extremely powerful.  If you swapped your eyes for a couple of the world's most powerfulmicroscopes, you'd be able to see things 100 million times smaller atoms.

4) laminar flow occurs at low reynolds number where viscous force is dominant so option 3 is ruled out. so correct answeer is that Laminar flow is an orderly flow, and Turbulent flow is a disorderly flow.

5) Zeroth law of thermodynamics has a standard statement which tells that two objects in thermal equilibrium with a third object are in thermal equilibrium with each other
