Answer:
I don't know about the oil part but "It is important to develop alternative
sources of energy because scientists are unsure of how long they will last"
Explanation:
Because they are nonrenewable resources, it takes hundreds to millions of years for them to be made again naturally. Once we're out, we're out. It would be a huge issue of that happened because Oil, Petroleum, and Natural Gas (all fossil fuels) are needed for heating, gas stoves, etc.
Answer:
603000 J
Explanation:
The following data were obtained from the question:
Energy required (Q) =...?
Mass (M) = 10000 g
Specific heat capacity (C) = 2.01 J/g°C
Overheating temperature (T2) = 121°C
Working temperature (T1) = 91°C
Change in temperature (ΔT) =.?
Change in temperature (ΔT) =T2 – T1
Change in temperature (ΔT) = 121 – 91
Change in temperature (ΔT) = 30°C
Finally, we shall determine the energe required to overheat the car as follow:
Q = MCΔT
Q = 10000 × 2.01 × 30
Q = 603000 J
Therefore, 603000 J of energy is required to overheat the car.

February 26, 1919
Explanation:
The main cause of the erosion that formed the Grand Canyon was water; most scientists agree that it formed when the Colorado River started carving through layers of volcanic rock and sediment between five million and six million years ago
