What can we learn from a continuous spectrum? A continuous spectrum contains many different colors, or wavelengths, with no gaps. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. Looking at absorption and emission spectra can tell you what elements are present in stars like the sun […]
What is earth wire?
What is earth wire? noun. A wire that provides an electrical connection to the ground. The purpose of an earth wire may be to protect against accidental electric shock (by providing a route for current that would otherwise pass through a person), or against possible damage (by limiting the increase in voltage that can occur […]

What are the factors on which internal resistance of cell depends?
What are the factors on which internal resistance of cell depends? Thus, the internal resistance of a cell depends on the factors like distance between the electrodes, the temperature, the effective area of the electrodes and the concentration of the solution. Does internal resistance of cell depends on the current draw from the cell? No. […]
How much wood can you split in a day?
Will all the carbon-14 eventually disappear?
Will all the carbon-14 eventually disappear? The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay. After 50,000 years, a fossil won’t have any radiocarbon left in it. Carbon-14 will have all disappeared by radioactive decay. How can you tell how old a […]

What happens to a barrier island as sea level rises group of answer choices? What happens to a barrier island as sea level rises? Structures on the island are at risk due to increased erosion. Peat deposits are exposed on the ocean beach side of the barrier island. What will happen to the crust as […]
What are the two things needed for velocity?
What are the two things needed for velocity? Since, velocity is a vector quantity, it has two components to it. The magnitude, which is the speed, and the direction in which the motion is happening. What 2 things does a person need to know to determine the velocity of an object? One must include direction […]
Should an immersion heater be left on all the time?
How can earthquake be prevented?
How can earthquake be prevented? We cannot prevent natural earthquakes from occurring but we can significantly mitigate their effects by identifying hazards, building safer structures, and providing education on earthquake safety. By preparing for natural earthquakes we can also reduce the risk from human induced earthquakes. What is the longest earthquake? Valdivia Earthquake Is a […]
