The diagram shows the schematic symbol of a transistor. Which is the correct label for the part of the transistor
marked with an X?
Х
base
outlet
gate controller
electrical supply

base

Explanation:

In the schematic symbol of a transistor, the arrow in the symbol indicates the direction of flow. There are three terminals namely, emitter, collector and base.

When you apply 0.7V from base to emitter you will turn the transistor ON and allow a current to flow from collector to emitter.

With the x in the picture the base must be indicated because all other answers do not make sense.

D. Electrical supply

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).

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
