Question 2 A block of ice of temperature 0°C and mass 20 g was placed in a beaker and weighed. The total mass was
55 g. Steam at 110°C was ducted onto the ice until the ice completely melted. Assuming no loss of heat to
the surroundings, find the mass of the beaker and its contents! [2mks]​

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?
