Answer:
50.8 watt
Explanation:
we know that P=W÷t
W=F.S S-->distance=50 ft= 15.24 m
F=ma
=100×10=1000 N
SO W= 1000×15.24
=15240 J
NOW
P=W÷t t=5 mints = 5×60=300 sec
P=15240÷300
P=50.8 watt
Answer:
There is much more friction on the rough surface than there is on the smooth surface.
Explanation:
In this question force is measured in g cm/s2 so we know that to get the answer we times g by cm/s2
50 × 20 = 1000
I believe all the insulators would be glass, wood, plastic, and yarn.
But I’m not entirely sure if mechanical pencil lead is an insulator or conductor.
Hope this helps.
