What is the gravity method?

What is the gravity method? The gravity method involves measuring the gravitational attraction exerted by the earth at a measurement station on the surface. The strength of the gravitational field is directly proportional to the mass and therefore the density of subsurface materials. What are the two main types of Gravimeters? There are two types […]

What percentage of air pollution is from cars?

What percentage of air pollution is from cars? Seventy-five percent of carbon monoxide emissions come from automobiles. In urban areas, harmful automotive emissions are responsible for anywhere between 50 and 90 percent of air pollution. All told, that’s quite a lot of air pollution coming from our vehicles. What is a antonym for smog? (clearness) […]

Does Matter have volume and mass?

Does Matter have volume and mass? Matter is all the “stuff” that exists in the universe. It has both mass and volume. Mass measures the amount of matter in a substance or an object. Volume measures the amount of space that a substance or an object takes up. What is mass weight and volume? A: […]

Does a battery have to move on a throw to third?

Does a battery have to move on a throw to third? The short answer is “nothing.” Unless the batter makes a movement that hinders the catcher, or otherwise intentionally impedes using his body or bat, the batter is pretty much immune from interference if he remains still in the batter’s box. If the catcher’s throw […]

What is convection current in the mantle?

What is convection current in the mantle? Convection currents are identified in Earth’s mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth’s crust. Why is […]

What is the dumbest color?

What is the dumbest color? Pantone 448 C, also referred to as “the ugliest colour in the world”, is a colour in the Pantone colour system. Described as a “drab dark brown”, it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was […]

What is the advantage of a bacteria being rod shaped?

What is the advantage of a bacteria being rod shaped? Another benefit of a rod-like shape is the inherent breaking of symmetry, allowing the cell to concentrate molecules at specific cellular locales. Despite their small size, bacteria are capable of concentrating proteins at different locations in the cell. Where can rod shaped bacteria be found? […]
