An iron bar is heated. its length, l, in millimetres can be modelled by a linear function, l= mt + c,

where t is the temperature measured in degrees celsius (°c).

at 150°c the length of the iron bar is 180 mm.

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.
