Answer:

Distance=\sqrt{\frac{Luminosity 4\pi }{App Brightness} }

Explanation:

The formula for apparent brightness is given by the next inequation:

B=\frac{L}{4\pi d^{2}  }

Where B equals apparent brightnes, L equals luminosity and D equals distance.

SO we just have to clear distance from the formula and are left with the inequation to calculate distance:

Distance=\sqrt{\frac{Luminosity 4\pi }{App Brightness} }

All of these are ways a society can improve its productivity Except. A) Education B) Regulation C) Technology D) Trade
Brrunno [24]
The answer in this scenario is regulation (Answer B).

Education results in a more skilled and productive work force, technological advancement improves efficiency and therefore productivity, and trade promotes increases in productivity.

Regulation, while necessary in many industries, is a form of restriction. This often means it drives up the cost in providing goods and services which dampens productivity. It's important to note that regulation is a very important tool to protect certain aspects or parties within an industry. For example, regulation is often in place to limit the maximum price that consumers (like you) can be charged for essential services like energy, water and sewerage.

I carried out a series of experiments testing the effect of caffeine on mice. I used two mice. I fed one mouse caffeinated water
grigory [225]

Answer:

I didn't have enough mice in the study.                

Explanation:

Validity: In psychological research, the term validity is defined as a particular test's capability of measuring what the test is required to measure. In validity, the term valid refers to strong.

Types: Construct, face, criterion, conclusion, internal, and external validity.

In the question above, they said that the results were not valid because I didn't have enough mice in the study. For any research to work properly or give rise to a valid result then the research should include enough subjects to analyze the effect and therefore by having only two mice doesn't prove the study to be valid.
