A 65 centimeter guitar string is fixed at both ends. In the frequency range between 1.0 and 2.0 kHz, the string is found to resonate only at frequencies 1.0, 1.5, and 2.0 kHZ.
Determine the speed of traveling waves on this string?
v=__________m/s
A pulse travels on a string 8.0 m long and 12 g mass. If the tension in the string is 32 N, how long does it take the pulse to travel the length of the string
Two positive point charges q1 = 12C and q2 = 48C are a distance 0.25 m apart. Find all the points where the total electric field is zero
An AC voltage source, with a peak output of 120V, results in dissipation of energy in a resistor at rate of 100W. What is the value of the resistance
a charge of 3.10?c is held fixed at the origin. a second charge of 3.10?c is released from rest at the position 1.25 m
A hypodermic needle consists of the plunger of circular cross-section that slides inside a hollow cylindrical syringe. When the plunger is pushed, the contents of syringe are forced through a hollow needle.
Brakes cause a frictional force of 2.5 N to the left to stop a 0.975-kg toy car traveling on a level surface at 3.75 m/s to the right. Calculate how far the car will travel while the brakes are being applied before the car finally stops.
point charges q1 q2 and q3 are fixed at the vertices of an equilateral triangle whose sides are 2.40 m long. find the
As a sailboat sails 53.0 m due north, abreeze exerts a constant force F1 onthe boat's sails. This force is directed at an angle west of duenorth. A force F2 of the same magnitude directed due north would do the same amount of work on the sailboat ove..
A race car rounds a curve at 53 m/s. The radius of the curve is 450 m, and the car's mass is 620 kg. What is the centripetal force acting on the car
