Identify the following situations, law of inertia, law of acceleration, or law of action - reaction 1. A frog leaping off his lily pad is pulled downward by gravity and lands on another lily pad instead of continuing on in a straight line

2. As the fuel in the rocket ignites, the force of the gas expansion and explosion pushes out the back of the rocket and pushes the rocket forward

3. After you start up your dirt bite, as you give it more gas, it goes faster

4. When you are standing up on a subway train, and the train suddenly stops, your body continues to go forward

5. An ice skater pushes harder with his leg muscles, he begins to move faster

6. A pitched baseball goes faster than one is gently thrown

7. When you paddle a canoe, it goes forward

8. You let an untied balloon go

9. When you dive off a diving board, you are pushed down on the springboard

10. If you kicked ball in space it would keep going forever due to no gravity in space

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).

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
