Answer:
Choice A. P = I² · R where
- P is the power in the DC circuit,
- I is the current through the circuit, and
- R is the total resistance of the circuit.
Step-by-step explanation:
Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work 
that the electrical force do when it moves charges 
across a potential difference 
:
W = 
.
The power is the rate at which the electrical force do the work:
.
On the other hand, current 
is the charge through a cross-section of the circuit in unit time. By the definition of current:
.
.
Consider Ohm's Law:
.
Therefore
.
$150 = 1 month
Movie ticket=$15
Ballet ticket=$35
Money spent
1 ballet ticket=$35
3 movie tickets=(3x15)=$45
Money spent =$80
Money left=(total amount-money spent)
=($150 -$80)
=$70
Ballet shows Julie would be able to attend=$70/$35
=2
Julie would be able to attend two ballet shows and stay in her budget
$3.15 would be the cost, after the mark up is added.
Answer:
wydm
Step-by-step explanation:
This is how you work it out:
u + xy
Plug in your numbers that you know:
20 + 9 * 8
20 + 72
92
