Option C
The fact that voltage can be created by exerting force on a crystal is used in Knock sensor
<u>Explanation:</u>
Any knock to an engine exhibits as a little shake that is distinguished by the knock sensor. This sensor acts by altering the fluctuation to an electrical sign, which is later transferred to the processor mastering the ignition system.
There the variation in quake to the voltage sign modifies the timing improvements on the kindling. The knock sensor is placed on the engine base, cylinder cap or consumption manifold. This is because its purpose is to sense fluctuations affected by engine knock or explosion.
Hi alexander it is very true air pollution is only caused by human activity
equilibrium i think if not sorry
Answer:

For constructive interference

For Destructive interference

where 

m=order of maxima and minima
for second order maxima i.e. 
For smallest separation taking 



Answer:
Explanation:
The sun is made up of 6 parts. Namely:
- The core
- The radiation zone
- The convection zone
- The photosphere
- The chromosphere and
- The corona
The convection area is just above the radiation zone. As materials from the suns core are heated, they rise above the radiation zone towards the EDGE of the convection area then sinks back again into the radiative zone for more heat.
The radiative zone is 12.6 million Fahrenheit hot and is just above the core.
The core of the son is not solid but plasma whose motion is like gas. Its temperature stands at 48 million Fahrenheit
