What is Charles Darwins theory of evolution? Charles Darwin’s theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve. What are the 5 evolutionary forces? Five […]

How far away should cell phone be when sleeping? 3 feet How cell phone radiation affects the body? If RF radiation is high enough, it has a ‘thermal’ effect, which means it raises body temperature. There are concerns that the low levels of RF radiation emitted by mobile phones could cause health problems such as […]

How do Batholiths form quizlet? How do Batholiths form? They form from plutons that begin as blobs of magma beneath the surface that slowly rise to the crust and clump together forming a huge mass. What is a Laccolith and how does it form quizlet? A laccolith is a lens-shaped pluton that has pushed the […]

Will touching lava kill you? Most lava is very hot—about 2,000 degrees Fahrenheit. At those temperatures, a human would probably burst into flames and either get extremely serious burns or die. What happens when you heat up a diamond? Diamonds Burn Like Anything Carbon If strongly heated in the presence of oxygen (air), carbon will […]

What is the reaction of magnesium with oxygen? When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO). What happens when […]

What is the mass of an object that is experiencing a net force of 200 N and an acceleration of 500? Answer. Answer : Mass of an object is 0.4 kg. What is the acceleration of the wagon? The wagon accelerates at 0.85 m/s2. How is acceleration related to the mass of wagon? When the […]

What would happen if ice didnt float? If ice did not float, life underwater would be impossible! It stays on the top and ice slowly gets thicker, freezing our lakes and ponds from the top down. When lakes and ponds freeze, the ice on the surface forms pockets of air and helps insulate the water […]

How do you tell if a particle is speeding up from a position graph? Something that goes from standing still to moving must be speeding up, so just to the right of each of t=1 and t=3 should count as speeding up. Conversely, just to the left of each of t=1 and t=3 the particle […]

What are 5 examples of potential energy? Examples of Gravitational Potential Energy A raised weight. Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released. River water at the top of a waterfall. A book on a table before it falls. A […]
