Avector is a quantity with both magnitude and direction. in problems involving vectors, we sometimes need the unit vectoropens in new tab. this operation takes a vector and divides it by its magnitude. create a function (prob2_5.m) that, given a three-element vector, r, will calculate the three-element vector, u. the operation is described below: where rx, ry, rz are the components of the vector r. do not use any built-in unit vector functions in matlab

Examine the information. a runner travels 10 m/s forward for 10 seconds. which of the quantities in the sentence would be considered a vector quantity, and why? the quantity 10 m/s is the only vector quantity because it is a measurement of speed. the quantity 10 s is the only vector quantity because it measures time. the quantity 10 m/s is the only vector quantity because it is a measurement that includes a direction. the quantities 10 m/s and 10 s are vector quantities because these numbers are both measurements that do not include direction.

The magnetic vector of a plane electromagnetic wave is described as follows: b =k b, cos[(10 meter")y+(3x10° s'); ] where k is a unit vector in the 2-direction, y is in meters, and is in seconds. (a) what is the wavelength 1 of the wave? your answer can contain a. indicate units! (b) what is the period t of the wave? your answer can contain a. indicate units! (c) in which direction does this wave propagate? be sure to indicate the direction of propagation with a unit vector (i, j, or k ) and an appropriate sign (+ or briefly explain why you choose this direction. (d) write an expression for the electric vector e of the wave in terms of the quantities given and the speed of light c. be sure to indicate the direction of the electric vector with a unit vector (i, j, or k ) and an appropriate sign (+ or (e) what is the time-dependent poynting vector associated with this wave? do not time- average. be sure to give both magnitude and direction, and write the magnitude in terms the speed of light c, b., and h., in addition to the numerical constants given. do not use e, in your final expression.

The vpython command norm returns the unit vector of a vector. remember that a unit vector has a length of one and points in the direction of the original vector. for exampe, if l = vector(0,3,0) then norm(l) = < 0,1,0> and, if l = vector(0,3,0) then norm(-l) = < 0,-1,0> additionally, if l = vector(0,3,0) then norm(5l) = < 0,1,0> and, for example, if m = vector(1,1,0) then norm(m) = < 0.707,0.707,0> . another example, if n = vector(2,3,0) then norm(m) = < 0.5547,0.83205,0> an for another example, if p = vector(1,2,3) then norm(p) = < 0.267261,0.534522,0.801784> if q = vector(3,4,0) then norm(q) =
