For this case we have, by definition, that:
Resistance is a component that is responsible for limiting the amount of current that can pass through a circuit, converting excess heat.
Consume energy.
Option A represents a swicth, option B represents a luminaire and option D represents a voltage source.
So, the correct option is C,
Answer:
Option C
If there is really no friction and no air resistance, then <em>NO force</em> is needed to keep an object moving in a straight line at constant speed. Check out Newton's first law of motion again.
Answer;
V = 14.7 m/s
Explanation and solution;
Vx = V cos theta
Vx = 16m/s × cos 28.08
Vx = 14.1 m/s
Vy = Vsin theta
Vy = 7.51m/s
t = d/Vx
t = 16.8m/ 14.1
t= 1.191 s
Now, find Vy at t= 1.191
Vy = Vy - gt
Vy = 7.51 - 9.81*1.191
Vy = - 4.18 m/s
V = sqrt (Vy^2 +Vx^2)
V= sqrt (4.18^2 + 14.1^2)
V= 14.7m/s
