Power (rate of using energy) = (voltage) x (current)
Power of this heating element = (120 V) x (3.2 A) = 384 watts
The easy way:
384 watts = 0.384 kilowatt
(0.384 kilowatt) x (5 hours) = 1.92 kilowatt-hour
Another way:
384 watts = 384 joules per second .
(384 joule/sec) x (3600 sec/hour) x (5 hours)
= (384 x 3600 x 5) (joules) = 6,912,000 joules.
Answer:E.
a straight line sloping upward (atmospheric CO2 levels would not seasonally oscillate, but would have increased over time)
Explanation: Photosynthesis is the process through which green plants and certain other organisms make their food using carbon dioxide and water in the he presence of Sunlight.
During photosynthesis, energy conversion from light energy into chemical energy takes place.
Photosynthesis is one of the major processes that helps to eliminate and reduce the quantity of carbon dioxide in the atmosphere,it also serve to make oxygen present in the atmosphere.
C.half the energy is carried by the electric field and half is carried by the magnetic field.
Here i state the conservation of energy rule and use that to justify my answer. I showed how to manipulate percentages to get the final answer of 11000J (2sf). Hope I'm right xx
