Answer:
<h2>E. 650N</h2>
Explanation:
step one:
given
length of stretcher= 2m
weight of stretcher=100N
Wayne weighs =800N
distance of Wayne weighs from chris's end= 75cm= 0.75m
The force that Chris is exerting to support the stretcher, with Wayne on it, can be computed by taking moments of the weight of the stretcher and Wayne weighs about Chris's end, the end result is the reaction at Chris's end
Taking moment about Chris's end
The moment of Wayne weight 75cm from Chris+ Half the weight of stretcher 1m from Chris
0.75*800+50*1=0
600+50=0
650N
Answer:
No, because pressure is determined by force and the area over which that force acts.
Explanation:
If 50 identical light bulbs are connected in series across
a single power source, then the voltage across each bulb
is ( 1/50 ) of the voltage delivered by the power source.
5.6 which would be acidic!
