Fumigation
|
Spraying
|
|
In this in a sealed area a highly lethal gas is sprayed which is quite harmful
|
In these gases that are used are not lethal to a very high extent.
|
|
In this area is not sealed after the fumigation process and entry of persons is banned for a certain period of time
|
In this area is not sealed and it also allows entry of people just after few time.
|
|
This is performed in many laboratories or factories at a very large scale where biosafety is a major concern
|
It is perfomed in houses, fields just to control pests.
|
|
For example Ethylene dibromide is used in fumigation process
|
For example malathion is used as a chemical in spraying.

An automobile engine propels a $1,000 \ kg$ car $A$ along a levelled road at a speed of $36 \ km\ h ^{-1}$. Find the power if the opposing frictional force is $100 N$ . Now, suppose after travelling a distance of $200 m ,$ this car collides with another stationary car $B$ of same mass and comes to rest. Let its engine also stop at the same time. Now, car $B$ starts moving on the same level road without getting its engine started. Find the speed of the car $B$ just after the collision.
