A silicon diode in an adapter rectifying circuit has a carrier density of 10-21in p material and 1022m-3 in n material, the temperature of the charger changes from 25°C
to 40°C, find the change in barrier potential of the diode.

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

Consider a graph for the equation y= -3x+4. what is the y intercept? a) 4 b) -4 c) 3 d) -3
