Find a vector of magnitude 5 perpendicular to both A and B.Find the sum of the vectors (4, 90^o) and (3, 180^o), and write the solution in polar form.Let the polar coordinates of the point (x, y) be (r, \theta). Determine the polar coordinates for the points: a. (...
Dot product of two vectors {eq}\vec a {/eq} and {eq}\vec b {/eq} is given by the following relation; {eq}\begin{align*} \vec a \cdot \vec b = |\vec a||\vec b|cos \ \theta \end{align*} {/eq} where {eq}|\...
It could be 3D with a k component that is 0. I've interpreted it like that for convenience. Curl is indeed only defined in 3D, but for 2D we can define it as the magnitude of the cross product of the 3D curl with the unit vector in the z direction. ...
Then force F of magnitude 220N is applied perpendicular to the rod at a distance R = 5cm. Find the magnitude of the force compressing stopper A and stopper B. Homework Equations I'm not sure how elasticity even plays into this problem... Should I treat this as an equilibrium type ...
Two harmonic waves are described by y1=(6.00cm)sin(\pi(\frac{2.00}{m}x+\frac{3.00}{s}t))\\ y2=(6.00cm)sin(\pi(\frac{2.00}{m}x-\frac{3.00}{s}t)) What is the magnitude of the displacement (in cm) of th Find the ampl...
To test your new class, you can create a three-dimensionalvelocity vectorof a falling snowflake, for example, which might look like this: Python >>>snowflake_velocity=Vector(0.42,1.5,0.87)>>>abs(snowflake_velocity)1.7841804841439108 Notice how callingabs()on yourVectorclass instance returns the...

Consider the given vector field. F(x,y,z) = (x+yz)i + (y+xz)j+ (z+xy)k a) Find the curl of the vector field. b) Find the divergence of the vector field.Find the y-component of their vector sum r? What is the magnitude of their vector sum...
Find a vector v in the opposite direction to w = (-1, 4, 1) and with a magnitude of 6 units. Find the unit vector in the direction opposite to v = <1, -3>. Find the unit vector in the direction opposite to \vec v = \langle -1,-3 \rangle ...
directional derivative and decreases most rapidly in the opposite direction of its gradient. If we want to calculate the maximum rate of decrease at a point, we have to calculate the gradient vector of the function...
