An electrician is creating a wiring plan for a small house. He needs to create a plan that will allow the homeowners to turn off

lights in one room without turning off the lights in another. What should he do to assure that each room's lights function independently of one another?
A) He should wire each room in series with the next.
B) He should wire each room in parallel with the next.
C) He should make sure each room's lights provide the same resistance.
D) He should wire the room with the most lights directly to the circuit breaker box.

So the answer is B) he should wire each room in parallel. This is because when the bulbs are in parallel if one part of the parallel circuit is broken (eg when you switch a light off) then the current can still flow to all the other bulbs, meaning they stay turned on. Hope this helps :)

You calibrate a set of automobile springs using a 25 kg car battery, attached to a rope that runs over a pulley, as shown in the
Goshia [24]

For an automobile spring using a 25 kg car battery, the spring constant is mathematically given as

K=4.08.3N/m

<h3>What is the spring constant?</h3>

Question Parameter(s):

a 25 kg car battery

The springs are pulled out by 0.06 meters

Generally, the equation for the Force  is mathematically given as

F=mg

Therefore

F=(25*9.8)

(25*9.8)=K(0.06)

K=4.08.3N/m

In conclusion, the spring constant

K=4.08.3N/m

By what factor would your weight change if the earth's diameter were doubled and its mass were also doubled?
coldgirl [10]
Aha! This is a fun question, likely AP Physics 1 if I'm not mistaken. This is how you solve it, you need the following equation.

F=G\frac{m_{1} *m_{2}}{r^2}

Now on this question you don't need to actually use the mass and diameter of the earth as we are only looking at the factor of how much your weight would change, so you can just plug in some random numbers for the mass and radius. In my case I will use the original radius as being 2 meters and the original mass of the earth as being 20kg. You can actually just omit the mass of your body and the gravitational constant isn't necessary to be multiplied by because they will remain the same in both scenarios.

Original weight:

F= \frac{20kg}{2^2m}
F=5N

So the original weight in this circumstance is 5N. Now then if we double the mass to 40kg and the radius to 4m you will have the following.

F= \frac{40kg}{(4)^2m}
F=2.5N

So the original weight was 5N and after doubling the mass and radius the weight reduced to 2.5N. This means the factor which your weight would change by is .5 or decrease by 1/2.

I hope this helps you :) You can ask me if you have any additional physics questions.
