The reason behind fatter seals using less energy to swim to the surface at the end of a dive, allowing them to take longer, more productive dives.

Question

1.39 Given two vectors A = -2.00 +3.00 +4.00 and B=3.00 +1.00 -3.00k. (a) find the magnitude of each vector; (b) use unit vectors to write an expression for the vector difference A - B; and (c) find the magnitude of the vector difference A - B. Is this the same as the magnitude of B - Ä? Explain.
