With the values you've given, only velocity can be found.
Acceleration is rate of change of velocity
d= 250s
t= 17s
a= d/t
=
= 4.7
The rate of doing work is called POWER.
Power is also defined as the rate of transfer of energy. It measures the speed of how work is done.
The unit of power is WATT.
Power is computed by dividing WORK DONE by TIME TAKEN.
P = W/t
1 watt:
*power of a machine
*power of an agent that does work at the rate of 1 joule per secon
1000 watt = 1 kilowatt
1000 kilowatt = 1 megawatt
Answer:
a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature's chances of living longer and producing more offspring)
