What happens when satellites crash? The Short Answer: Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth. How […]
What was early Autotroph called?
What was early Autotroph called? Photoautotrophs What is an example of an Autotroph? Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. Why are humans referred […]
How do I make sure everyone has clean water?
How do I make sure everyone has clean water? 5 ways to improve water quality and access to water Improve sanitation facilities by providing toilets and latrines that flush into a sewer or safe enclosure. Promote good hygiene habits through education. Implement rainwater harvesting systems to collect and store rainwater for drinking or recharging underground […]
How does photon interact with matter?
How does photon interact with matter? Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain. What happens if an incident photon collides with a moving […]
How much is Alaska worth today?
How much is Alaska worth today? The Alaskan Purchase Today, Alaska is, of course, worth much more than that.

Which gun has the most recoil?
Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]
What are the negative effects of infrared?
What are the negative effects of infrared? IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. Can infrared radiation kill you? Infra-red light affects […]
When should I watch the Perseid meteor shower?
When should I watch the Perseid meteor shower? Perseid meteors have been streaking across our skies since around July 17. We’ll see Perseids for 10 days or so after the peak mornings on August 11, 12 and 13, though at considerably reduced numbers. Yet, each day as the moon wanes in the morning sky, less […]
Why does a rocket keep accelerating?
Why does a rocket keep accelerating? As the rocket velocity increases, it encounters air resistance, or aerodynamic drag, which opposes the motion. Drag increases as the square of the velocity. The thrust of the rocket must be greater than the weight plus the drag for the rocket to continue accelerating. Do Newton’s laws apply in […]
What is another word for isotope?
What is another word for isotope? What is another word for isotope? element form variant version What is the correct statement about isotopes? Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons. Thus, we can conclude that the statement isotopes of the same […]
