Answer:
a) 12.74 V
b) Two pairs of diode will work only half of the cycle
c) 8.11 V
d) 8.11 mA
Explanation:
The voltage after the transformer is relationated with the transformer relationshinp:
the peak voltage before the bridge rectifier is given by:
The diodes drop 0.7v, when we use a bridge rectifier only two diodes are working when the signal is positive and the other two when it's negative, so the peak voltage of the load is:
As we said before only two diodes will work at a time, because the signal is half positive and half negative,so two of them will work only half of the cycle.
The averague voltage on a full wave rectifier is given by:
Using Ohm's law:
Velocity is Displacement / Time
In order for Velocity to Accurately get a winner, you should be able to determine the race by looking at <em><u>How Far the competitors are from the starting point in the shortest amount of time
</u></em><u />so the answer should be something like : a 5 mile course from the center of the town heading north to the outskirts of the town
Probably false. but correct me if i’m wrong
Answer:
180m to the east
Explanation:
Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.
point A runs 150m east,
70m west
100m east
150m
--------------------------------------------------------→
70m
←---------------------
100m
-----------------------------------→
The displacement of the athlete = 150 - 80 + 100 = 180m to the east
