Explanation

• Coal, fossil fuels, crude oil, natural gas, etc are all hydrocarbon fuels.
• These are called as non-renewable source of energy because they take millions of years to regenerate themselves.
• Water energy is renewable because it is regenerated by water cycle.
• Also wind energy and solar energy are renewable sources of energy.

Explanation

The most popular renewable energy sources currently are:

1.      Solar energy

2.      Wind energy

3.      Hydro energy

4.      Tidal energy

5.      Geothermal energy

6.      Biomass energy

Explanation

Non-renewable energy sources:

• Oil
  
• Nuclear energy
• Petroleum
• Natural gas & coal

Renewable sources of energy:

• Solar energy
• Wind energy
• Hydroelectric power
• Biomass energy
• Geothermal energy
• Tidal energy

Explanation

• Sound energy is the energy created by the vibration of particles, such as molecules or atoms, as they oscillate back and forth.
• This vibration creates a disturbance that travels through a medium, like air, water, or solids, and is perceived as sound.

Explanation

Combustion is when fuel reacts with oxygen to produce heat.

Chemical reactions that produce heat we call exothermic reactions.

Most vehicles use an engine to convert heat energy into mechanical energy.

 Mechanical energy gets transferred to the vehicle's moving parts, like wheels or propellers.

Explanation

Kinetic energy is the energy an object has because of its motion.

Explanation

The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling.

Explanation

Water reuse is the method of recycling treated wastewater for beneficial purposes, such as agricultural and landscape irrigation, industrial processes, toilet flushing, and groundwater replenishing

Explanation

Many practical and proprietary methods exist to avoid plastic shrinkage cracking, including various curing methods, power floating, the use of cold water, shrinkage reducing admixtures, and fibres.

Covering concrete with plastic sheets or wet burlap is the most common practical concrete curing method.

Explanation

Ground water recharge includes recharge as a natural part of the hydrologic cycle and human-induced recharge, either directly through spreading basins or injection wells, or as a consequence of human activities such as irrigation and waste disposal.
