Answer the fo​

Answer 1

Answer:

To minimize noise pollution we have to take certain steps:-

1. do not blow horn without any use.
2. hearing at high decibels should be banned after a certain period of time at night.
3. bursting of crackers should be strictly prohibitted as it causes air as well as noise pollution.

THREE POINTS ARE MORE THAN ENOUGH

Two astronauts cannot talk to each other in space because sound cannot travel through vaccum i.e. ( there is no air in space and sound needs a medium to travel ) therefore astronauts need to use a wireless radio to talk to each other.
