- At one point in space, the direction of the electric field vector Is given In the Cartesian system by the unit vector . If the magnitude of the electric field vector is E=400.0V/m , what are the scalar components , and of the electric field vector at this point? What is the direction angle of the electric field vector at this point?A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69Let vectors A =(2,−1,1), B =(3,0,5), and C =(1,4,−2) where (x,y,z) are the components of the vectors along i^ , j^, and k^ respectively. Calculate the following:
- Let vectors A⃗=(2,−4) A → = ( 2 , − 4 ) and B⃗=(−3,1) B → = ( − 3 , 1 ) . Calculate the following: What is the angle θAB θ A B between A⃗ A → and B⃗ B → ?Let vector A point from the origin into the second quadrant of the xy plane and vector B point from the origin into the fourth quadrant. The vector B −A must be in which quadrant?If vectors A = (4.5, -2.5) and B = (3, 6), what is C = 2A – B?
- On a plane flat surface with "up" given as +y and "right" given as +x, we add two vectors. One of them has components (4, 4). Their sum is (3,6). What is the unknown second vector and what is its angle to the x-axis? Hint: The angle is the one that has a tangent that is the ratio of its y to its x component, or a sine that is the y component divided by its length. The second vector is (-1,-2). It is about 63° down from -x. The second vector is (7,10). It is about 55° up from +x. The second vector is (1,-2). It is about 63° down from +x. The second vector is (-1,2). It is about 63° up from -x.Vector u = <-7,3,-5> and vector v = <-1,1,0>. Find u X (-9v)I need the answer as soon as possible
