U = I × R = 20A × 12 Ohm =240V
Umm, I guess it really depends on what these numbers are for but what I can say is if you put this under physics then decimals are used very often and help express parts of numbers for this particular problem.And if it's directly between the two then it's 0.50 added to that smaller number,I hope that helps
C. the left plate is positively charged
when looking at these arrows imagine there is a positive electron at the beginning of the arrow. Since the electrons are going towards the plate to the right it is attracted to the negatively charged plate. These electrons want to get away from the positively charged plate because same charges repulse each other
Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
<u>W = 30 N</u>
The answer is to the question is c
