Is it OK to use microwave everyday? (Of course, the heat in a microwave isn’t harmless — so you should never put, say, a living creature inside of a microwave. “Microwaves are part of the electromagnetic waves we’re exposed to daily. When you bake bread, you’re exposed to electromagnetic waves and infrared energy from the […]
Is gold a solute?
Is gold a solute? Not all solutions are liquids. Solutions can also be solids. In a solid solution, both the solvent and the solute are solids. In this case, gold is the solvent and the other metals are the solutes. Why is gold a homogeneous mixture? Because the material is uniform throughout, it is homogeneous. […]
What is the best evidence in the text for the prediction that Champollion will eventually figure out the T hieroglyph?
What is the best evidence in the text for the prediction that Champollion will eventually figure out the T hieroglyph? The only hieroglyph that confused Champollion was the one for “T,” which was different in the two names. What is the best evidence in the text for the prediction that Champollion will eventually figure out […]
Why does temperature increase as pressure increases?
Why does temperature increase as pressure increases? The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases. What […]
What kind of grass grows in the tundra?

Grasses in the Tundra Polar Grass (Arctagrostis latifolia) Polar grass grows from sea level to 5,500 feet in elevation with two subspecies growing in different parts of the world. Ice Grass (Phippsia algida) Vahl’s Alkali Grass (Puccinellia vahliana) Cottongrass (Eriophorum callitrix) Do pine trees grow in the […]
What does PreCambrian mean in Greek?
What does PreCambrian mean in Greek? Precambrian* – all the time prior to the start of the Cambrian (not a formal era/eon name) * synonymous with “Cryptozoic” – Greek for “hidden life” Proterozoic eon – Greek for “former life” What does period mean in geologic time scale?

Which group is very unreactive?
Which group is very unreactive? noble gases Why does group 18 have no charge? Noble gases are relatively inert and nonreactive due to their full outer shell of electrons. Having a full valence shell of 8 electrons means that the atom is already in its most stable state, and thus, there is no need for […]
What will be my mass if my weight is 50 kg?
What will be my mass if my weight is 50 kg? However, WEIGHT does vary given the gravitational well. A mass of 50⋅kg has a WEIGHT of 50⋅kg×9.81⋅N⋅kg−1=490.5⋅N on the earth, but a weight of 50⋅kg×1.622⋅N⋅kg−1=81.1⋅N on the moon…… What is a healthy weight for a 4 11 female? Height and Weight Chart Height Weight […]
What is the fastest maglev train in the world?
What is the fastest maglev train in the world? The highest-recorded maglev speed is 603 km/h (375 mph), achieved in Japan by JR Central’s L0 superconducting maglev on 21 April 2015, 28 km/h (17 mph) faster than the conventional TGV wheel-rail speed record. Which country has the fastest train? Countries With The Fastest Trains China […]
What are two ways to increase kinetic energy?
What are two ways to increase kinetic energy? If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word “kinetic” comes from the Greek word “kinesis” which means motion. Kinetic energy can be passed from one […]
