Normal force is mass x gravity, so mass x 9.81
Taking a shot in the dark here as i mostly deal with atomic structure and the fact i haven't handled a diverging mirror ut would it be a virtual image because that needs parallel normal lines which cannot occur
Answer:
Probably because the Bernoulli effect (lift) is insufficient in thinner air to keep the plane aloft - increasing the angle of attack will increase the lift on the airplane
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:
