What happens to a high energy photon after it strikes an electron? Photon hits the electron and give some of its energy and go in some different direction with larger wavelength. Electron will gain kinetic energy and move in some other direction. If the photon energy is large enough to knock a tightly bound electron […]

What are the 3 properties of radiation? What are the Three Types of Radiation? When atoms decay, they emit three types of radiation, alpha, beta and gamma.

How do you interpret z-scores? A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average. For example, if a z-score is equal to […]

What causes electric current in a circuit? An electrical phenomenon is caused by flow of free electrons from one atom to another. The characteristics of current electricity are opposite to those of static electricity. Wires are made up of conductors such as copper or aluminum. Electrons, which continuously move in wire, are called Electric Current. […]

What is the unit of 1 Joule? 1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. How many Earths make 1 Joule define […]

What happens when you break a rock? Broken rocks will respawn in a random location, so it might take a couple of tries to get them where you want to go. All of the rocks you break will respawn in a random spot on your island, but note that only one rock will respawn each […]

Which of the following resources is renewable? Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. This includes wood, sewage, and ethanol (which comes from corn or other plants). Biomass can be used as a source of energy because this organic material has absorbed energy from the Sun. […]

How do you tell when boiled eggs are done? The egg is done boiling if the thermometer reading is 158-170°F (70–77°C). If you get a lower reading, you should toss the egg back to the boiling pan and cook it some more. But if the reading is higher, you have overcooked the egg. Overcooked eggs […]
