What is the specific heat of a metal if it takes 15,000 J of heat to raise the temperature of 20 points a 620-9 sample from 15.0C to 85.0C?

Does any one know what real love is and would anyone be willing to share it with me?

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?
