How can you tell from a graph that an object is traveling at a constant speed?

The intensity, or loudness, of a sound can be measured in decibels (db), according to the equation , where i is the intensity of a given sound and is the threshold of hearing intensity. what is the intensity, in decibels, [i(db)], when ? use a calculator. round to the nearest whole number. 8 9 19 80

Due in 40 explain in terms of frame of reference if you’re inside a moving train everything on the outside can seem to be moving

What’s the kinetic energy of the object? use . erica is competing in the shot put event at a track meet. she hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. the shot’s kinetic energy is joules.
