Abrick moves across a rough surface at constant velocity. which of the following are forces that should be included in a free body diagram? (select all that apply) gravity friction applied force force of motion

the force that are included here is given as

1) Gravity

2) Friction

3) Applied force

Explanation:

As per the Force diagram of the moving block

We know that the block is moving with constant speed

so here the applied force on the block is counter balanced by the friction force due to ground

Also we can see that the the Normal force due to ground is also counter balanced by the weight or force of gravity on it

So the force that are included here is given as

1) Gravity

2) Friction

3) Applied force

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

answer: electrons
