Answer:
20.6 m
Explanation:
P₁ = Power of first bulb = 45 W
P₂ = Power of second bulb = 130 W
r₁ = distance from the first bulb
r₂ = distance from the second bulb = 35 m
Using the equation
Inserting the values
r₁ = 20.6 m
With 0.45 amp flowing through an 18-ohm resistor, the voltage across it is
V = I R = (0.45) x (18) = <em>8.1 volts .</em>
"But I asked for the battery voltage! That's the voltage across the resistor."
The ends of the resistor are connected directly to the battery terminals.
They're the same voltage.
"But what about the 6-ohm resistor ? Where does that figure in ?"
In parallel, it doesn't. It's also connected directly across the battery,
and it has its own current.
In parallel, neither resistor knows or cares whether or not there are
any other resistors present. In parallel, it makes no dif.
Answer:
The value of the fund today is $13831.72
Explanation:
Let us calculate the value at the end of each year, step by step. An annual decrease of 3% corresponds to a multiplier 1.0-0.03 = 0.97. An increase of 7% corresponds to 1.07.
Value at the end of
year 1: 12000 * 0.97
year 2: 12000 * 0.97 * 0.97
year 3: 12000 * 0.97 * 0.97 * 1.07
year 4: 12000 * 0.97 * 0.97 * 1.07 * 1.07
year 5: 12000 * 0.97 * 0.97 * 1.07 * 1.07 * 1.07 = 13831.72
The value of the fund today (end of year 5) is $13831.72
Yeah i think with a car or a plane:)
