How do they know the Earth is 4 billion years old?
Space & NavigationAll the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. How did geologists find out that the Earth is 4.6 billion years old? It
What is the general form for an exponential function that has an asymptote at y 0?
Space & Navigationy = 0 is a horizontal asymptote, toward which the graph tends as the x-axis continues to the left. Also note that the graph shoots upward rapidly as x increases. This is because of the doubling behavior of the exponential. In the form y = abx, if b is a number between 0 and 1,

What does 10x mean on a microscope?
Space & NavigationWe all know that 10X means that the objective lens has an effective magnification of ten times life size and when combined in the compound with a 10X ocular lens will give a final magnification of 100X (10 X 10). What magnification is 10x? Range of Useful Magnification based on NA of Objectives Objective (Numerical
What happens if you look at the eclipse without glasses?
