Natural Selection is that the species that are best suited or adapted to their environment or most likely to survive and reproduce
And after a few generations evolution occurs
Answer:
0-4 acceleration comes at 12 m/s where (B) stagnates at 12 m/s and remains for 4 seconds (C) is breaks being activated slowing the car to 6 m/s in 2 seconds and (D) over the course of 4 seconds brings the car to 10 m/s.
Explanation:
The correct option is d)greater input distance and a smaller force
Why?
We must remember that while a pulley has more rope sections, the force requiered to lift the load will be smaller, but the input distance required to lift the load will be greater.
Hence, for the problem, the correct option is d)greater input distance and a smaller force.
Have a nice day!
To find distance traveled, all you have to do is multiply a constant velocity by the time you are traveling at that velocity. So if you're traveling 55 m/s for 55.2 s, you should go around 3036 m, or 3.036 km in that time.
Explanation :
Distance is total path travelled by an object during its entire journey. It is a scalar quantity i.e only magnitude.
Displacement is the shortest distance covered by an object. It is basically the change in position of object. It is a vector quantity i.e direction as well as magnitude.
When an object is travelling in a straight line and stops at the end point, then both distance and displacement are same.
When an object is travelling in a straight line and then changes its direction or we can say come backwards then the magnitude of distance and displacement are different.
