Step-by-step explanation: Domain cannot repeat(have more than one output)
The voltage is a representation of the electric potential energy per unit charge.
The voltage across the circuit is 48 V. Option D shows the voltage across the circuit.
<h3>
What is the voltage?</h3>
Voltage is defined as the difference in electric potential between two points.
Given that a series circuit contains three 2 Ω resistors and a 6 Ω resistor. The current in each resistor is 4.0 A.
The total resistance across the series circuit is given below.

Where R is total resistance, R1, R2, R3 and R4 are resistors that are connected in series.


The resistors are connected in series hence the current flows across the two points of the circuit are the same which is 4.0 A.
The voltage across the circuit is,



Hence we can conclude that the voltage across the circuit is 48 V. Option D shows the voltage across the circuit.

118 degree because they are transition angles
Answer:
30
Step-by-step explanation:
Since the question says that it took her 45 minutes per hour, you can use that to find the distance of the route she took.
45 miles: 60 minutes
15 miles: 20 minutes ----------------cross multiply (20x45 and then divide by 60)
Therefore, if she is going to use the same route in reverse, the distance would be 15 miles.
Use the formula for speed:
speed= distance/time
= 15/0.5 ---------- 0.5 hours is the same as 30 minutes
= 30
T=PV/K
Starting with V=KT/P, multiply P on both sides to get PV=KT
Then divide K on both sides to leave T alone
And you get.....T =PV/K
