<span>In assumption that there were two scientists who used
different measurement systems in their research. The problems that might arise
if they shared their data is obviously and primarily error. Errors are
recognized and one element in every measure, system and quantity. Error was
already even present in the measurement system alone a scientist used and it
will furthermore aggregate, when these two different scales are combined the
more error escalates in the process. There are two types: random and systematic
error. </span>

The diagram below shows the heating of an unknown substance (it is not water). Its melting point is? Where is the diagram
Answer:
Explanation:
Given
velocity of skateboarder is 4.1 m/s
Force
time=20 s
As the motion is along x axis therefore
Power
Power
only x component of force comes into play because there is no motion in Y direction.
Work done will be
Work done on skate boarder by rope is 1148 J
and work done on bicyclist by rope is -1148 as the direction of velocity is opposite to applied force
