The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

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?
