What is the color of luster? Luster describes the reflection of light off a mineral’s surface. Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or non-metallic. Minerals that are opaque and shiny, such as pyrite, have a metallic luster. How many types […]

What is an example of kinetic friction? The kinetic friction is a part of everything and it interferes motion of two or more objects. The force acts in the opposite direction to the way an object wants to slide. If a car has to stop, we apply brakes and that is exactly where the friction […]

At what time of day is temperature the lowest the highest? The daily maximum temperature, or high, describes how warm you can expect the air to be, usually from 7 a.m. to 7 p.m. The daily minimum temperature, or low, tells how much the air is expected to cool, usually overnight from 7 p.m. to […]

Does mitosis occur in the body? Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division. Why is mitosis important for your body? Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in […]

Can you have negative magnetic field? Yes, magnetic flux can be negative. It just depends on where the field is going. Say there is a sheet and magnetic field is going through it from front to the back, we can call the flux there as positive and negative when it’s the other way round. How […]

Do I really need a torque wrench for spark plugs? Ideally anything that has a torque value should be torqued to that value. With spark plugs the concern is not normally getting them tight enough, but instead to prevent over-tightening. On most items, you don’t need to get it to the exact torque, you just […]

How does a loss of species diversity affect an ecosystem? “Our results show that future loss of species has the potential to reduce plant production just as much as global warming and pollution.” In ecosystems where species losses fall within intermediate projections of 21 to 40 percent of species, however, species loss is expected to […]
