Answer: Option (B) is the correct answer.

Explanation:

Radiation involves transfer of energy or heat with the help of electromagnetic waves.

For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.

Thus, we can conclude that Sunlight travels through space without the aid of fluids or solids describes how heat is transferred by radiation

We know that :
1 cal (th) = 4.184 J
1 J = 0.2390057361 cal (th) , so :

•55.2 j to cal > 13.193116635 cal
•110 call > 460.24 joule
•65 kj > divide the energy value by 4.184
= 15.535 kilocalories calorie (IT)

Converting form C to F > (F-32)*5/9Understand it better if we have Fahrenheit just add to the equation mentioned to find Celsius.
+to find F to C> (9/5*C)+32

•425 Fahrenheit = (425- 32) × 5/9 =218.33333333 Celsius

•1935 C = 3515 F
———————————-
Converting Celsius to kelvin,We know that :
K = C + 273.15
C = K - 273.15
And from F to K=9/5(F+459.67)
And K to F =(9/5 *k)-459.67
•39.4 Celsius = 312.55 kelvin
•337 Fahrenheit = (337+ 459.67) × 5/9 =442.594 kelvin

how does photosynthesis and respiration in plants influence the amount of co2 in the atmosphere during a year?
Oliga [24]

Answer:

An increase in the amount of CO2 well increase the rate of photosynthesis, Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction.Increased amount of CO2 will increase the rate of photosynthesis to a certain limit, after which a further increase in its amount will no longer increase the rate any further.

Hope this helps.

Cheers! :)
