How many horsepower is a human? 1.2 hp Why does a horse have 15 horsepower? While it is true that the maximum output of a horse is around 15 horsepower, when you average the output of a horse over the course of a work day it ends up being around a horsepower. Watt defined this […]
Can you sit on a cloud?
Can sound create a magnetic field?
Can sound create a magnetic field? – just created by collisions of atoms in the air and the pressure waves created travels in air and gets to your ear drum and the membrane vibrates and if the frequency is right you hear a sound. … Do magnetic fields vibrate? SUMMARY The vibration of a perfectly […]
What characteristics are used to identify metamorphic rocks?
What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
What do you notice about the iron filings?
What do you notice about the iron filings? All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at […]

Are there sharks in the Columbia River?
Are there sharks in the Columbia River? Some say it could be a Salmon Shark. The two look similar. “It’s not very often we see sharks in that area of the Columbia River, but it does not mean they are not there” ODFW spokesperson Rick Hargrave said.

What are the six question words? The words are Who, What, Where, When, Why and How. These posters give simple definition of what is required to answer these question starters. They can be printed and placed in plastic sleeves or page protectors or you can print them poster size for your writing areas. What are […]
Do polar molecules have to be asymmetrical?
Do polar molecules have to be asymmetrical? Polar molecules MUST have an asymmetrical structure to be polar, because symmetry cancels out net charge. Asymmetrical molecules are always polar. Symmetrical molecules can be polar and non-polar. Polarity is dependent on the difference in electronegativity of the molecule’s atoms and shape. What is an example of asymmetrical? […]
What happens if you block potassium channels?
What happens if you block potassium channels? Activation leads to an increase in conductance and the termination of action potentials, hyperpolarization, and a reduction in excitability. Conversely, a block of the channels leads to depolarization, prolongation of action potentials, repetitive firing, and increases in transmitter release and endocrine activity. What happens if potassium leak channels […]
