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.

this is a good question! i'll do some research and come back when i have the answer!

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
