Answer:
Explanation:
as we know that 1dm3 =1000cm3
therefore x dm3 =120 cm3
1000X =1*120
X dm3 =120/1000=0.12
so 120 cm3 =0.12 dm3
now the number of moles of carbon dioxide at RTP is
moles =given volume(dm3)/standard volume at RTP
moles=0.12dm3/24
moles =5*10^-3

Scientists use special tools to do their work. They gather data, or information, as they seek to learn about the world. In order to solve problems they must record data that is accurate and organized. This is an important part of the scientific method.
Explanation:
( a )
<u>The four types of spread spectrum techniques are as follows -</u>
1. Direct sequence spread spectrum .
2. frequency hopping spread spectrum .
3. chirp spread spectrum .
4. time hopping spread spectrum .
( b )
<u>The Direct sequence spread spectrum was devised for eavesdropping in the military .</u>
In the field of telecommunications , the Direct sequence spread spectrum , it is the technique of spread spectrum modulation which is used to reduce the overall inference of the signal .
