Answer:
Mutations do not necessarily always have to be bad, sometimes plants or animals mutate with something helpful to the situation they are in.
Answer:
During start total turns
After half of the time total turns
Total number of turns during it stop
After half of the time total turns
Explanation:
Initially the machine is at rest and then starts rotating with speed 3550 rev/min
now we will have
now we know that it took 10 s to reach the speed
so angular acceleration is given as
now it stops in 31 s so the angular deceleration is given as
now initially number of turn to reach the given speed
number of turns during it stop
Now during startup speed after t = 5 s is given as
now during it stop the speed after half the time is given as
now the number of turns is given as
Compute the work done on the table:
<em>W</em> = <em>Fd</em> = (320 N) (32 m) = 10,240 J
Divide this by the given time duration to get the power output:
<em>P</em> = <em>W</em>/∆<em>t</em> = (10,240 J) / (150 s) ≈ 63.3 W
A ) decrease.
B ) increase.
C ) increase, then decrease.
D ) not change.
The answer is A) decrease
Take pushing a box, for example-- You push your hardest then give out, still trying to push the box. You are doing less work than what you have started with!

The average<span> speed of an object is defined as the distance traveled divided by the time elapsed. </span>Velocity<span> is a vector quantity, and </span>average velocity<span> can be defined as the displacement divided by the time. Hope this answers the question. Have a nice day.</span>
