Triply charged uranium-235 and uranium-238 ions are being separated in a mass spectrometer. (The much rarer uranium-235 is used as reactor fuel.) The masses of the ions are 3.90 × 10-25 kg and 3.95 × 10-25 kg, respectively, and they travel at 2.8 × 105 m/s in a 0.27 T field
What is the separation between their paths in meters when they hit a target after traversing a semicircle?
A rotating wheel requires 3.08-s to rotate through 37.0 revolutions. What is the constant angular acceleration of the wheel
A 1300 {rm N} crate slides 13 {rm m} down a ramp that makes the angle of 30^circ with the horizontal. If the crate slides at a constant speed, how much thermal energy is created.
Draw a cube and Cartesian axes. All points of the cube lie in the (+,+,+) octant of the coordiante system. One vertex of the cube is at (0,0,0), the point called O.
In a certain RLC circuit, the RMS current is 6.42 A, the RMS voltage is 235 V, and the current leads the voltage by 55.6°. Calculate the average power dissipated in the circuit
A meter stick lies on the bottom of a 100 cm long tank with its zero mark against the left edge. You look into the tank at a 30 angle, with your line of sight just grazing the upper left edge of the tank.
Assume that positive -axis is directed toward the direction of motion of cart 2.
A 1300- {rm N} crate slides 15- {rm m} down a ramp that makes an angle of 35^circ with the horizontal. If the crate slides at the constant speed, how much thermal energy is created.
In compressing the spring in a toy dart gun, 0.9 J of work is done. When the gun is fired, the spring gives its potential energy to a dart with a mass of 0.05 kg, What is the dart's speed
A wooden block weighing 7 N is at rest on top of a wooden desk. The coefficient of static friction between the block and the desk is 0.41. Find out the minimum horizontal force required to move the block if the following occurs.
