Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) minus (speed at the beginning)
Change in speed = (-58 m/s) minus (54 m/s)
Change on speed = -112 m/s
Acceleration = (-112 m/s) / (0.8 s)
Acceleration = -140 m/s²
Answer:
P = 2234400 Watt
Explanation:
Power generation is given as rate of work done
Here the turbine generator is located at 120 m below the free surface
So here rate of work done is given as rate of potential energy


so we have

now we have

so the power generation potential will be 2234400 Watt
Answer:
I think B but I could be wrong
Explanation:
C. motion can be defined as change in position.
Mass extinction occur from natural disasters, such as a n asteroid hitting earth or a volcano errupting and spread ash everywhere.
It makes sense to measure geologic time between mass extinctions because after each mass extinction, there is almost no life left and the few left have to repopulate, which may lead way to new mutations and new varieties of plants and animals.
