Consider two vectors, A~ = 3.00ˆx + 2.50ˆy and B~ = 1.50ˆx − 2.00ˆy. (a) Calculate the magnitude of each vector. (b) Express the difference B~ − A~ in terms of the Cartesian unit vectors ˆx and ˆy. (c) Find the magnitude and direction of B~ − A~ and express the direction as an angle relative to ˆx. 7.a) Find the scalar product of the two vectors from the previous problem. Note that the scalar product yields a scalar result (one component). (b) Find the vector product of the two vectors. \Note that the vector product yields a vector result (three components). (c) Find the angle between them.

7.study the scenario. a small container of water with a low temperature is poured into a large container of water with a higher temperature. which choice correctly explains what happens to the thermal energy of these systems? the smaller container of water has more heat and thermal energy than the larger container. some heat and thermal energy is transferred to the larger container of water. the larger container of water has more heat and thermal energy than the smaller container. some heat and thermal energy is transferred to the smaller container of water. the larger container of water has more thermal energy and some of that energy is transferred to the colder water in a process known as heating. the smaller container of water has more thermal energy than the larger container, and some of that energy is transferred to the warmer water in a process known as heating.
