Answer:

a. 1nC

b. 0C

Explanation:

Net charge q stored on plate of capacitor is

q = CV

Where C = 2uF = 2 x 10^-6F

V= 50v

q = 20 x 10^-6 x 50 = 1000 x 10^-6 = 1000uF = 10^-9 = 1nC

b. the total net charge on another plate is equal in absolute value to the first one, but it is charged with opposite Pole so always is valid that total net charge on both plates are equal to zero.

That's the other charge on the plate is -1nc

1 nC + -1nC = 0C

icang [17]

Answer:

C) low-ball technique.

Explanation:

The low ball sales technique is legal, although it is also deceiving. It refers to a technique where a good or service is offered at a low price to attract customers' attention, and then the product or service is offered at a much higher price to include all the amenities or functions initially offered.

This is a very common car sales technique where a car is advertised at a certain price and the features offered correspond to a higher trim. Once the customers approach the dealership, they are told that the advertised price was for the basic model and that the advertised car is actually worth much more.
