100 kw of power is delivered to the other side of a city by a pair of power lines with the voltage difference of 13014.1 v.
FinnZ [79.3K]
A) The power delivered to the lines is
P_{in}= 100 kW=1 \cdot 10^5 W
And the voltage at which the lines work is
V=13014.1 V
Since the power delivered is the product between the voltage and the current:
P=VI
We can find the current flowing in the lines:
I= \frac{P}{V}= \frac{1 \cdot 10^5 W}{13014.1 V}=7.68 A

b) The voltage change along each line can be found by using Ohm's law:
\Delta V = IR = (7.68 A)(10 \Omega)=76.8 V

c) The power wasted as heat along each line is given by:
P_d = I^2 R = (7.68 A)^2 (10 \Omega) = 590 W
And since we have 2 lines, the total power wasted as heat in both lines is
P_d = 2 \cdot 590 W=1180 W

Ann has a geography test next Friday. She needs to know all the US states and their capitals. Provide three effective techniques
Mumz [18]

Answer: THIS IS THE EXACT ANSWER

Three effective techniques Ann could use to learn all the US states and their state capitals are visualization and association, creating a mnemonic device, and rhyming. She could learn some of the states and their capitals by visualizing her own experiences in or about the state. As an example of association, if Ann visited Idaho last winter to see her twin brothers, she might think “I went to Idaho to visit the boys” (sounds like Boise). By employing association, she connects her own life experience to the information she wants to remember to make recalling the information easier. To remember the capital of Washington, Ann might create a mnemonic device like “George Washington went to the Olympics” (Washington’s capital is Olympia). Mnemonic devices organize information to encode it in a way that helps with recall. To effectively use rhyming, she might remember Michigan is a northern state and use “Reindeer prancing in Lansing.” Rhyming provides a cue that helps with recall. All three of these techniques work in the encoding and retrieval stages.
