= t(Vf + Vi/2)
<span>Vf + Vi/2 = d/t </span>
<span>Vf = (d/t) - Vi/2 </span>
<span>Answer: Vf = (d/t) - Vi/2 OR (2dt - Vit)/2t

The answer is B. Transfer electrons
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:
Velocity of electron will be 
Explanation:
We have given distance across the plate d = 2 mm 
Potential difference V = 6 volt
We know that potential difference at any distance is given by
V = Ed , here V is potential difference, E is electric field and d is distance
So 
Charge on electron 
We know that expression of velocity is given by 
, here q is charge on electron, E is electric field and d is distance
So 
Answer:
