Answer:
Once the fridge is moving you are still applying the same push force but now the opposing friction (now kinetic) force is less.
Energy conservation
mgh = 1/2mv^2
1.5*9.8*3 = 1/2*1.5*v^2
44.1*2 = 1.5*v^2
88.2/1.5 = v^2
58.8 = v^2
v = 7.668 m/s
Least count of the pulse stopwatch is given by
this means each division of the stopwatch will measure 0.1 s of time
After 3 journeys from one end to other we can see that total time that is measured here is shown by the clock as 52nd division
So here total time is given as
Time = (Number of division) (Least count)
now we will have
Answer:
Because this pole is different from the original pole that magnetized the paperclips, the top paperclip will become demagnetized in the opposite direction and the bottom paperclip will be repelled away
It is incorrect because the two types of ions in sodium phosphate cannot be seen.
