Physics Questions

All of the factors that contribute to global winds are 

1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells

Gamma rays has the shortest wavelength and radio waves has the longest wavelength.

Conduction is the movement of heat through a substance by the collision of molecules. It occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature.

Wind and solar energy are examples of Renewable energies. 

Renewable energy sources are those which can be naturally replenished. 

Nuclear Power Plant uses a Non Renewable Energy Source.

Non-renewable energy is that source of energy which can not be used again and again. This sort of energy is sustainable to exhaustion.

Non renewable energy is that form of energy which is subject to deletion. This type of energy is of many uses to us. It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy.

Microscopes are of three types. They are :

1) Optical microscopes

2) Electron microscopes

3) Scanning tunneling microscopes

Scanning tunneling microscopes are the microscopes that are used to view metal surfaces.

450 mm Hg denotes the air pressure.

Metamorphism is the method of changing the structure of a rock by using heat and temperature.

Hence, for this to happen the parent rock must be in solid form only. Therefore, option C) is true.
