Two waves, and are given by the equations y1 = 2.5 sinπ(x + 5t) and y2 = 2.5 sinπ(x + 5t) . (a) Determine the equation of the standing wave. (b) Determine the position of the first 4 nodes of the standing wave.
the intensity of the sound from a certain source is measured at two points along a line from the source. the points are
Blood flows through a vein at a rate of 3.5 mL/s. Among other things, it contains a protein with a molecular weight of 63,000, at a concentration of 2.9 g per 150 mL. How many grams of this protein are carried by the blood each second?
In an experiment designed to measure the speed of light, a laser isaimed at a mirror that is 59.0 km due north. A detector is placed122 m due east of the laser. The mirror is to be aligned so thatlight from the laser refelects into the detector.
A sinusoidal voltage ?v = (65 V) sin (130t) is applied to a series RLC circuit with L = 10 mH, C = 120 ?F, and R = 50 ?. What is the maximum current in the circuit
A baseball of mass 0.15kg approaches a batter at 30.0 m/s. Consider the ball as traveling horizontally toward the batter in the negative x-direction so that V= -30.0 i m/s. What is the work done by the bat on the ball
A component with a 19 Ω resistor is rated for use at power levels not exceeding 11 W. How much current can safely flow throught the component
The figure shows a closed Gaussian surface in the shape of a cube of edge length 1.6 m, with one corner atx1= 4.6 m,y1= 4.5 m. The cube lies in a region where the electric field vector is given by E = -3.4 i -3.8 y2j+2.8 k N/C, withyin meters.
When striking, the pike, a predatory fish, can accelerate from rest to a speed of 3.7 m/s in 0.11 s. How far does the pike move through this strike?
A glass is half-full of water, with a layer of oil (n =1.46) floating on top. A ray of light traveling downward during the oil is incident on the water at an angle of 70.8°. Take the refraction index of water to be 1.333. (a) Decide the critical angl..
