Which of these best describes a situation where science is used?
a. choosing a career after graduation
b. brushing teeth after having dinner
c. ordering food in a restaurant by looking at a menu card
d. predicting the weather by looking at the clouds

The correct answer will be option-B.

Explanation:

Science is a systematic approach to understand and explain the natural phenomenon occurring in an area.

The explanation of any phenomenon or process taking place can be approached through following scientific methods which include: asking a scientific question based on predictions, background research and formation of hypothesis which can be tested through experiments and observations.

In the given question, predicting the atmospheric weather after looking at the clouds in the sky is the situation where scientific methods can be applied as the situation starts with the observation and prediction of the atmosphere which could lead to the generation of a scientific question.

Thus, Option-B is the correct answer.

we can see how the government has failed them.

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).
