Subject: General Science

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 cerebellum is a structure in the hindbrain. It coordinates movement, balance, and learning.

Explanation
Secondary consumers are organisms that eat primary consumers for energy.  In the above options, only goat is a primary  consumer. Primary consumers are herbivores, feeding on plants.

Explanation
Sound waves are longitudinal waves. When longitudinal waves travel through any given medium, they also include compressions and rarefactions.

Explanation
Dentist mirrors are typically concave mirrors. The examples of convex mirrors: Rear-view mirrors Blind Corner mirrors  Security mirrors

Explanation
The  Indian  Space Research Organization (ISRO)   is the national space agency of India.

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
The roadway would cause diffuse reflection due to its rough surface some examples where diffused reflection Desert sand, disturbed water surface, and rough roads  

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
The nephron is the microscopic structural and functional unit of the kidney There are almost  1000000 of  nephrons in each kidney in the human body

Explanation
The quantity of matter in a body is called its mass . while  Force is a push or pull acted on an object . Weight is the measure of the force exerted on the mass of the body due to gravity.

Explanation
The SI unit of volume is the cubic meter (m3), which is a derived unit. 1 m3 = 1 m • 1 m • 1 m. *** The  SI unit  of energy/work is the  joule (J) The SI unit of charge is Coulomb The Pascal is the SI-derived unit of pressure The ampere,  symbol A , is the SI unit of  electric current. The SI unit of power  is the watt, one joule per  second. The SI unit of  electric resistance  is the  ohm (Ω). The  SI unit  of temperature as per the International System of Units is  Kelvin   Unit of torque: newton metre ( N m ) The SI unit of velocity is a meter per  second (m/s). The SI unit of acceleration is  meters/second2 (m/s2)

Explanation
The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) , and tonne (t). 1000 g = 1 kg. 1000 kg = 1 tonne. Mass was first defined in 1795 Symbol : M

Explanation
The SI unit of acceleration is meters/second^2 ( m/s^2 or ms^-2) Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity.
