The voltage at terminal a is -8 volts and the voltage at terminal b is 5 volts. what is the voltage difference between the two terminals?

Voltage difference is 13 volts

Step-by-step explanation:

If voltage A () is -8 volts, and voltage B () is 5, the voltage difference is calculated via the formula  

When estimating a difference between quantity A and another quantity B it is custom to perform the difference built as the last quantity mentioned, minus the first one.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
