How then does water move up the height of a 40 m tall tree?
How then does water move up the height of a 40 m tall tree? Water is move up the tree by using cohesion-tension, transpiration pull and the root pressure, technical they all happen at the same time; However, the cohesion-tension get it up to the 10m mark and the transpiration pull and the root pressure […]
Which statement is an electrolyte?
Which statement is an electrolyte? Which statement describes an electrolyte? An electrolyte conducts an electric current as a solid and does not dissolve in water.

Why do both bumper cars stop after a crash physics?
Why do both bumper cars stop after a crash physics? When working with collisions, kinetic energy must be worked out for each object involved both before and after the collision. If two bumper cars collide head-on in a fairground and both cars come to a stop due to the collision, kinetic energy is obviously not […]

What does a station model show?
What does a station model show? In meteorology, station models are symbolic illustrations showing the weather occurring at a given reporting station. Elements in the plot show the key weather elements, including temperature, dew point, wind, cloud cover, air pressure, pressure tendency, and precipitation. What pressure levels are mandatory to report? When the upper atmosphere […]
How do you write 0.000070 in scientific notation?
Can a cloud freeze?
Can a cloud freeze? Clouds do freeze in extreme temperatures. Cirrus clouds, which are the highest, are not liquid droplets, but rather ice crystals. What confuses me is why you believe that freezing to solid crystals would make them fall from the sky. The ice crystals do not weigh any more than water droplets would. […]
Is fungus a virus or bacteria?
Is fungus a virus or bacteria? Fungi are more complicated organisms than viruses and bacteria—they are “eukaryotes,” which means they have cells. Of the three pathogens, fungi are most similar to animals in their structure. What’s the difference between a parasite and a virus? Bacteria and viruses can live outside of the human body (such […]
