First of all, we need to convert the energy produced from kilojoules to calories. 1 kJ corresponds to 239.1 cal, therefore:
And so now we can calculate the energy value of the oil:
Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
Since the plant is falling, the gravitational energy decreases, so it means b) kinetic energy is increasing.
Hope this helps!! :)
