Can neutrons bounce off metal?
As neutrons do not carry a electric charge they do not interact with the electron cloud that surrounds atoms so the inclination to bounce isn't there as much as with other atoms or charged particles. Instead a neutron would preferably
- travel straight through the mostly empty space of a metal.
- collide with an atomic nucleolus.
If it collides with a nucleolus it can either
- bounce off
- get absorbed
- get absorbed and start a fission reaction.
What is one of the least productive of all ecosystems?
Deserts are often considered one of the least productive ecosystems due to their low precipitation levels and limited plant growth. This leads to fewer resources available for supporting diverse wildlife and plant species compared to other ecosystems.
No, the military communication site in the Upper Pennisula is operated by the US Navy and is used for communication over super-long wave radio with submarines that are at depths below the capability of conventional communications. It may not even be in operation still.
Specially designed amunition that can seek out and destroy plumbers in red hats. they are easily stopped by being jumped on. A good description would be a giant bullet with spike teeth and an evel grin.
How are maps and models the same and how are they different?
A map is in 2D, printed on a flat sheet of paper. A model is 3D, allowing you to examine it from all sides. They are both scaled version of larger object
Which part of the skeleton protects eyes?
The skull, specifically the orbit, is the part of the skeleton that protects the eyes. The orbit is a bony cavity in the skull where the eyes are located, providing them with protection from injuries and outside elements.
What is microbes and what is thermophilic and mesophilic microbes?
Microbes are organisms that are composed of only one solitary cell or a cell which lives in a colony with other cells.
Thermophilic microbes are organisms that prefer to live in areas with a temperature that is higher than the normal.Mesophilic are these microbes that prefer areas with moderate temperature.
What is an investigatory project?
An investigatory project is:
- a planned undertaking in a particular field of science.
- an undertaking which applies certain specific principles / scientific ideas.
- a reseach activity which aims to develope one's ability and determine possible solutions to a particular problem

Which axis of a graph will always run vertically from the botton to the top of the page?
typically the y-axis. sometimes it changes when it fits the graph better, but always put the y-axis as the vertical one unless told to otherwise.
when you get to 3-D drawins the y-axis is usually the vertical one but sometimes it changes.
He most likely Mike will have to measure or compare the masses of some objects. MIKE HAS HUGE OBJECTS THAT HE MEASURES EVERY NIGHT . HE HAS MEASUREMENTS IN YOUR MOMMYS MOUTH AND HE PUTS IT IN TO SEE HOW DEEP IT WILL GO..THATS HOW MIKE MEASURES HIS OBJECTS
Can you relate endospore staining to endospore survival in hospital or other environments?
Endospores are highly resistant to environmental influences. Most disinfectants cannot permeate it. Because bacterial endospore walls are not readily permeated by materials in solution, the inner contents of the endospores are not easily stained by ordinary bacterial dyes. The relation is that it is not killed or stained by ordinary methods.
What are the answers to Pearson Prentice worksheet convection and the mantle?
1.convection 2.radiation 3.conduction 4. 5. 6.false 7.true 8.true 9.false 10. False
What is the difference between the working voltage and test proof voltage for dielectric footwear?
Working Voltage is the voltage at which the boot is safe at. Test Proof voltage is what the boot was tested up to before it failed. However you must keep in mind that if you are in wet conditions that can significantly lower the rating of the boot. Also voltage does not kill you it is the amperage.
What is the economic importance of lime?
Lime, CaCO3 is the principal feedstock used in the manufacture of cement. Its other principal use is in agriculture where is is used to improve the soil by adjusting the pH, and thus improving the vegetation. Tom Sawyer had a minor use for it in painting a fence.
Why would a Mento in a Diet Coke cause more fizzing than in a regular Coke?
The regular coke contains a higher amount of solute (sugar, corn syrup) compared to the diet version which uses concentrated artificial sweetener. The slightly-higher viscosity (thickness) of the regular Coke slows the nucleation of carbon dioxide on the surface of the Mentos candy. The thickness also means that it takes more force to lift the liquid out of the bottle (less height to the gas-driven foam fountain).
