Two waves are traveling in opposite directions on the same string. The displacements caused by the individiual waves are given byy1=(30.0 mm)sin(9.39πt -1.66πx) and y2=(39.0mm)sin(3.54πt + 0.552πx). Note that thephase angles (9.39πt - 1.66πx) and(3.54πt + 0.552πx) are in radians,t is in seconds, and x is in meters. Att = 5.00 s, what is the net displacement (in mm) of thestring at (a) x = 2.22 m and(b) x = 2.57 m? Be sure to include thealgebraic sign (+ or -) with your answers.

An airplane is flying with a velocity of 82 at an angle of 25 above the horizontal. When the plane is a distance 125 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will ..
If the current price of July WTI futures is $87 and the strike price is $86, illustrate what is the intrinsic value of this call? Illustrate what is the time value?
The vibration of a system in the ground state is called zero point motion, because the molecule is at zero kelvin. The tips of air plane wings(mass of order 10^4 kg) oscillate in flight (period of 1 s, amplitude of 0.1 m), could this be zero point mo..
