When the detonators set off the explosives, the pusher compresses the core with the spherical shockwave of the explosions to a high density, triggering the core to become critical. The neutron initiator inside the core is crushed as the core compresses and releases neutrons. These neutrons cause a chain reaction to occur in the core, which makes the bomb explode with overwhelming power. This type of bomb can carry either a uranium core or a plutonium core and is much more destructive than the gun-type bomb. Both the Gadget and Fat Man were implosion-type bombs that were fueled by the plutonium isotope,
The particles have a big play on the earthquakes. Convection currents are happening in the asthenosphere. These are particles going in a circular motion. This was discovered in the “Convection Currents Lab”. The candle, acting like the inner core was heating up the liquid inside the jar, acting like the asthenosphere and its particles.
Explain what is meant by relative atomic mass?- Relative atomic mass is the measure of the mass of an element which consists of the protons and neutrons; it is always the bigger number and has the symbol Ar. An obvious example of this is oxygen has the Ar of 16 yet sodium has the Ar of 23. Explain how relative formula mass is calculated using the periodic table- You need to find the relative atomic mass (M) for each atom but this can only be done when the relative atomic mass have been found, then you add all of the masses in the compound together to find the RFM. Sodium Hydroxide is the example we used within our experiment.
These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
Fracking is a method of getting natural gas out of the ground. The way fracking is done is by drilling down into the earth vertically until getting into the layer with gas in it where there you drill horizontally. Once at the location of the rock with gas inside it from there a water mixture is directed at the porous rock to release the gas inside. The water mixture contains water, sand , and a mixture of over 700 chemicals. The mixture is injected at the rock at high pressure it fractures the rock so the gas is released.
Professional should tell you the risks and benefits of having the extension before applying for the extensions. They should also care to ask about any conditions you have that would make you unsuitable for the procedure. It is only a myth that eyelash extension will ruin your natural lashes. When applied correctly, they are safe and will not ruin the health of your own lashes. Just make sure not to pull the extensions or tug your eyes, as this can make the lashes fall out or damage your own.
Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
Introduction In the lab “Gravity Demos,” the common objective is to learn more about gravity and the center of gravity by performing various experiments. The definition of gravity is an attraction between any objects that have mass. Every planet has a gravitational pull, for example, earth’s gravitational pull is 9.8 meters over seconds squared (9.8 m/s2). This means that a bowling ball and a feather would fall at the same speed and hit the ground at the same time if there wasn’t air resistance (a force that slows down objects that move through the air.)
Furthermore, quartz crystals found near the Cretaceous-Tertiary Boundary were detected to show a distinctive pattern of fracturing caused by high-energy impacts or explosions (“What Killed the Dinosaurs?”). All things considered, the a dramatic asteroid impact may as well be the reason why dinosaurs don’t coexist with us humans
Just to be on the safe side, here are some potential issues and how to prevent them. *Injuring your fingers – It is recommended to keep your fingers at least 3 inches from the blade. Use your thumbs to push the blade forward. *Malfunctioning – Never force a cut.
It is their job to reduce the amount of radiation as low as they possibly can so it will not affect any patient nor themselves. Time is an important method of reducing radiation exposure because you have too be aware of everything taking place. You would not want to leave somebody in the lab for a while, that way they do not experience a high amount of radiation. The further back a technician stands, reduces the amount of radiation they could possibly receive. Raza confirms, “ The barriers they have the technicians standing behind is made of lead so that the radiation does not get on the technician nor the patients” (Raza
Even some warm water and a mild soap can help get the most annoying smudges off. Do not use any scrubbers that will scratch, and avoid powdered cleaners. Take good care of your football display cases if you want to enjoy viewing your sports collectibles for an even longer amount of time, without the need to buy replacement cases. Old Ghost Collectibles can help you display all of your sports memorabilia so that everyone can see it and enjoy it with you, and you can also find a blog full of tips on displaying your items, at
The author, Molly Merryman, earned her Ph.D., from Bowling Green State University in 1995 in American Culture Studies. She teaches at Kent State, and is associated with History and Justice Studies, American Studies, and Women’s programs. She is also a documentary film maker, who has received national and international screenings and awards, along with three Emmys. Merryman’s book, Clipped Wings, includes a useful index, that has cross-referencing for both topics and names. The bibliography of this book is organized into categories of different sources, such as articles, books, government documents, etc.
Physics 132 Hasbrouck 212 Cassidy Grace Lab 6: Radioactivity Abstract In this experiment we studied the strength of radioactive elements using the properties of ionizing radiation. The sources we used in this experiment are alpha, beta, and gamma radiation. We also studies the principles of the Rutherford experiments in that the nucleus was found to be very small because the forces that hold it together and also that the protons and the neutrons reside in the nucleus.
