Answer:1.63 m
Explanation:
Given
mass of block 
inclination 
Amount of work done 
block slides a distance s along the Plane
Work done =change in Potential Energy
Increase in height of block is 
Change in Potential Energy 
I would say unlimited polarity because the compass’s needle is always attracted to Earth’s north pole.
Good luck to you!
Answer
graph 2
Explanation
Velocity is the rate of change of displacement.
Velocity = (change in displacement)/(change is time)
In graph 2, the gradient of the curve is positive, indicating that the velocity is positive.
Acceleration is the rate of change of velocity.
The steepness of the slope of the same graph (graph 2) is decreasing. This shows that the velocity is decreasing hence a negative acceleration.
I would say that the answer to this is the last option: ALL OF THE ABOVE. A lean fuel or air mixture, incorrect spark plug heat range, and a blocked carburetor bowl vent would be among the reasons of an engine to surge and hunt at the top no-load speeds. Hope this answer helps.
