Answer:
Both Technician A and technician B are correct.
Explanation: A transistor must have a P-N junction as that is where the positive and negative charges are connected.
A transistor also can be described as a semiconductor which acts as a switch and can be used to amplify currents. Transistors are very key and vital to electronic devices especially the mobile phones in recent times, it helps to ensure that electronic systems perform optimally.
The charges in the P-N junction is controlled by the availability of Positive and negative electrons.
Answer:
It wouldn't get any louder then maybe 3db more
Explanation:
There's even a equation if you wanted to check this out but, if they are the same generator same model and all and made the same precise noise it wouldn't increase more then 3db.
Answer:
diameter= 1 in
Explanation:
Some authors have developed studies to find the recommended flow rate at the pump outlet, in order to avoid high pressure losses and cavitation.
Assuming that this pump carries water, the recommended speed is 2m / s, so knowing the flow rate = 20gpm we can find the diameter of the pipe.
Q=flow rate=20gpm=0.0012618m^3/s
V=speed=2m/s
A=Area
Q=VA
A=Q/V
Taking into account that the flow is through a circular pipe we can use the equation to find the area of a circle, and then find the diameter
the result is 23.34mm, if we find the closest commercial diameter to this value, we find that it is 25.4mm = 1in
