The magnitude of an earthquake is calculated using the richter scale, , where i0 is the threshold intensity and the intensity i is given in terms of multiples of that threshold intensity. which is the correct expression to find the magnitude of an earthquake that had the intensity 980 times the threshold intensity?

Which type of bond is found between the atoms of a molecule? a. metallic b. delocalized electron c. covalent d. ionic

In science and physics what is the standard unit of measure for speed?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
