Suppose you are 100 feet away from a large building and you clap and it takes 185 milliseconds for the sound to reflect back what is the speed of sound used in this measurement?

The round trip distance is 200 feet. The speed in this case is 200 / .185, or 1081 feet per second.

How can you reflect?
you can reflect in thought, or reflect some thing in a Mirror. There's other ways to reflect to.
Significant digits are the number of digits that reflect the precision of a measurement or number?
Not necessarily. I measure my height to 3 sig figs (for example 178 cm), but I may choose to report is as 180 cm (to 2 sf).
Is it true significant digits are the number of digits that reflect the precision of a measurement or number?
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
Do funhouse mirrors refract or reflect?
reflect
Which smooth surfaces reflect light?
Any smooth surface will reflect light. The better question is "How much light does each kind of smooth surface reflect?"
How does this unique character of earth reflect on what enginners supposed to do?
They suppose to do the best as they can . but some in machinic is cheater.

What kind of feature is referred to as P200?
It is a waveform component which is measured on the human scalp. The aim of this is to reflect the post-synaptic activity of a specific neural process. The electrical potential peaks at 200 milliseconds which is where the name comes from.
Significant digits reflect true precision of a calculation but sometimes it is important for measurements to be?
rounded to a certain number of decimal places for consistency and ease of communication. It's important to consider the context and purpose of the measurement when determining how to round. Rounding can help prevent misinterpretation and allow for easier comparison of results.
How do you indicate uncertainty in a measurement?
You can indicate uncertainty in a measurement by reporting the measurement value along with an estimated error margin or range. This can be expressed as a ± value or a range within which the true value is likely to fall with a certain level of confidence. Additionally, using significant figures to reflect the precision of the measurement can also convey uncertainty.
Suppose you want to reflect a triangle across the line y = x. Which of the following is the reflection matrix that you should use?
0, 1 1, 0
Should your length measurements be to the same decimal?
No, it should reflect the magnitude of the measurement. You wold measure the length of a river in kilometres but its width in metres.
Why do significant figures represent the precision of a measurement and not its accuracy.?
Significant figures represent the precision of a measurement because they indicate the level of uncertainty in a measurement due to the limitations of the measuring tool used. Accuracy, on the other hand, refers to how close a measured value is to the true value. The number of significant figures does not necessarily reflect the accuracy of a measurement, as a measurement can be precise (consistent) but not accurate (close to the true value).
Why would painting rooftops white help save the planet?
I suppose it would reflect solar energy back into space rather than absorb it on earth
Will aluminum sheet reflect heat?
Yes, aluminum has high reflectivity and can reflect a significant amount of heat, which is why it is commonly used in applications where heat reflection is desired, such as in building insulation or automotive heat shields.
According to some scientists earth began as an iceball what early events led to the majority of the ice melting since snow is suppose to reflect sunlight and not absorb heat?
snow melts, right, therefore it doesn't reflect all heat. with global warming and the sun's help, most of the ice from what we call the ice age has melted.
Is there such thing as moon tanning?
I suppose it's possible that someone could develop something and call it that, but using just the simple usual meaning of the words, no. The moon does not reflect enough ultraviolet light for you to tan yourself by.
