An air column in a glass tube is open at one end and closed at the other by a movable piston. The air in the tube is warmed above room temperature, and a 356 Hz tuning fork is held at the open end. Resonance is heard when the piston is at a distance d1 = 21.2 cm from the open end and again when it is at a distance d2 = 68.3 cm from the open end. (a) What speed of sound is implied by this data? Changed: Your submitted answer was incorrect. Your current answer has not been submitted. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s (b) How far from the open end will the piston be when the next resonance is heard?
What is the speed of the arrow as it leaves the bow.Two point charges, Q_1 = -6.9 mu C and Q_2 = 2.0 mu C are located between 2 oppositely charged parallel plates.

A 124 balloon carrying a 22 basket is descending with a constant downward velocity of 25.2. A 1stone is thrown from the basket with an initial velocity of 19.9 perpendiculars to the path of the descending balloon.
Electrons which were initially at rest were subjected to a continuous force of 2×10-12 newton along the entire length of two miles (one mile is 1.6 kilometers) and reached speeds very near the speed of light.
The leg and cast weigh 220 N. find out the weight and the angle needed so that no force is exerted on the hip joint by the leg plus the cast.
A gymnast with mass m1 = 41 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 108 kg and length L = 5 m. Each support is 1/3 of the way from each end. at least the gymnast stands at the left end of..
