Two planes intersect in exactly one point . Always sometimes or never ?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Average acceleration: i have no idea how to do this.

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.
