Answer: A PN-junction diode is formed when a p-type semiconductor is fused to an n-type semiconductor creating a potential barrier voltage across the diode junction
Explanation: hope this helped
Answer:
True
Explanation:
Pressure is defined as:

where
F is the magnitude of the force perpendicular to the surface
A is the surface
Therefore, pressure is inversely proportional to the area of the surface:

this means that, assuming that the forces in the two situations (which have same magnitude) are both applied perpendicular to the surface, the force exerted over the smaller area will exert a greater pressure. Hence, the statement"
<em>"A force acting over a large area will exert less pressure per square inch than the same force acting over a smaller area"</em>
is true.
i would say, are sour and corrode metals
Awww im too late but im going to wait and see if he has it
Work = (force) x (distance) = (450 N) x (4 m) = 1,800 joules
Power = (work) / (time) = (1,800 joules) / (2 sec) = 900 watts .
