Three forces are applied to a wheel of radius 0.350 m, as shown in the figure . One force is perpendicular to the rim with 11.9N, one is tangent to it with 8.5N, and the other one makes a 40.0 degree angle with the radius with 14.6N. What is the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center?
A pipe open only at one end has a fundamental frequency of 282Hz. A second pipe, initially identical to first pipe, is shortened by cutting off a portion of the open end.
What is work done by the non-conservative force
Two spheres, fastened to "pucks" riding on a frictionless air track, are charged with +2 × 10-8 C, and +6 × 10-8 C, correspondingly. Both objects have the same mass. As they repel.
Friction and air resistance are negligible. Illustrate what speed does the ball have when the cable makes an angle of 30 degrees with respect to the vertical?
A gas expands while 502 J of energy is added to it as heat. The expanding gas does 422 J of work on its surroundings.
1.76- block at rest on a ramp of height. While the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 12.0 that has a coefficient of kine..
find the angular speed after the grindstone. what must be its minimum mass so that material on its surface remains in place during the rapid rotation.
An electron is shot upward directly perpendicular to the lower plate of a parallel plate capacitor. Its initial velocity is 3.0 x 104 m/s. What must be the potential of the upper plate if the electron stops just before reaching it? The lower plate..
A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 4.60 m/s2 over the distance of 20.80 cm. It then decelerates at the constant rate of 1.03m/s2 (because of friction), until it again comes to..
An airplane is flying in a horizontal circle at a speed of 520 km/h. If the wings of the plane are tilted 34° to the horizontal, what is the radius of the circle (in m) in which the plane is flying? Assume that the required force is provided entir..
A diving board length = 5.60 that weighs 210 is supported by two pillars. One pillar is at the left end of the diving board; other is distance = 1.60 away. Find out the magnitude of force exerted by the left pillar while an 85.0 diver stands at th..
