What kind of combination of mass, fan speed, and surface is best for taking the most mass across the 500 cm of track, but keeping it under 80 cm/sec,
which is a standard for safety in this cart type.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.
