What 3 things must you have with you when you drive? You should always keep three items in your car. Your vehicle registration and proof of insurance can stay in the glove box or someplace else where they will be easy to find and hard to lose. Your driver’s license is the third thing, and […]

What are 3 types of ocean currents? Two major kinds of currents define the planet’s oceans: surface currents driven by wind and deep-water currents driven by variations in seawater density. Surface Currents. ••• Deep-water Currents. ••• Measuring Currents. ••• Currents vs. Tides. Ocean Currents & Humankind. ••• What 3 things are ocean currents controlled by? […]

What is verbal communication and examples? Verbal communication is the use of sounds and words to express yourself, especially in contrast to using gestures or mannerisms (non-verbal communication). An example of verbal communication is saying “No” when someone asks you to do something you don’t want to do. What is a verbal or nonverbal response? […]

What is the significance of negative susceptibility? Explaining the reason behind the negative susceptibility of diamagnetic material. Susceptibility means how much is a particular substance allowing or tends to allow magnetic field to pass through it. Diamagnetic substance are those which repel magnetic field and henceforth its susceptibility is negative. What is the value of […]

How do you calculate wasted energy? It is computed Input Power minus output power. For example you have a PC power supply for your computer. You can measure the input power by taking AC measurements, say 1A at 120VAC = 120 Watts. The wasted power is 120W – 102 W = 18 W. What is […]

How are mass and size related? Is mass the same as size? No, mass is different than size or volume. This is because the type of atoms or molecules as well as their density helps to determine the mass. For example, a balloon filled with helium will have much less mass than a similar sized […]

There is no special process, but all relevant information about your educational and personal background is welcome. Is it harder to get into college if […]

What is the reaction pathway that absorbs energy? endothermic What type of reaction releases energy and does not require initial energy to occur? Chemical reactions Is δg positive or negative? Below 373.15 K, ΔG is positive, and water does not evaporate spontaneously. Instead, water vapor at a temperature less than 373.15 K and 1 atm […]

Why night sky is black? At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day. […]
