What was Squidwards hypothesis? In order to test his hypothesis, Squidward played a song on his clarinet for a total of 5 minutes and counted the number of jellyfish he saw in his front yard. Squidward’s hypothesis that the clarinet attracts larger numbers of jellyfish than other instruments is not proven by this experiment alone. […]
Why is diamond so precious?
Why is diamond so precious? The earliest recorded cultures used diamonds to portray strength, the value of love, and even instruments of magic. That value is likely due to a diamond’s natural strength and unique visual appearance in combination with its relative rarity. Even a low-grade gem-quality diamond is still a thing of value and […]
How does the solar radiation affect climate?
How does the solar radiation affect climate? Researchers have shown that UV radiation affects climate through direct heating and the production and destruction of ozone in the stratosphere, which then leads to regional effects at Earth’s surface through a complex chain of mechanisms. Do clouds absorb longwave radiation? The high, thin cirrus clouds in the […]
What is an example of entropy from everyday life?
What is an example of entropy from everyday life? A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel. Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are processes with increasing […]
Which of the following correlations is the weakest?
Which of the following correlations is the weakest? The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger. A negative correlation means that if one variable gets bigger, the other variable tends to get smaller. […]
What is the value of least count?
What is scalar multiple of a vector?
What is scalar multiple of a vector? In common geometrical contexts, scalar multiplication of a real Euclidean vector by a positive real number multiplies the magnitude of the vector—without changing its direction. The term “scalar” itself derives from this usage: a scalar is that which scales vectors. What is it called when you add two […]
Does NASA use the metric system?
Does NASA use the metric system? Although NASA has ostensibly used the metric system since about 1990, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units. Why SI units […]
What is the formula for the angle of impact?
What is the formula for the angle of impact? By accurately measuring the length and width of a bloodstain, you can calculate the impact angle using the following sine formula: c=opposite/hypotenuse=width(a-b)/length(b-c). To determine the angle of impact, take the inverse sine to get degrees. How does the angle of impact affect the appearance of drops […]
How long does it take for water to evaporate at room temperature?
How long does it take for water to evaporate at room temperature? 1.2 hours Does stirring affect evaporation? If you stir, you do several things: You agitate the air above the liquid, thus facilitating the diffusion of vapor away from the surface; this increases the rate of evaporation (similar to blowing on the surface) You […]
