Q. Two isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 x10-27 kg and 21.59 x10-27 kg, respectively. These two isotopes are singly ionized (+e) and each is given a speed of 6.00 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.8900 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.
A 0.230- coffee cup at 19 is filled with 0.240 of brewed coffee at 97. The cup and the coffee come to thermal equilibrium at 79.If no heat is lost to the environment, what is specific heat of the cup material.

An asteroid is discovered heading straight toward Earth at 14 km/s . An international team manages to attach a giant rocket engine to the asteroid. The rocket fires for 10minutes , after which the asteroid is moving at 28degrees to its original pa..
Imagine that the coefficient of kinetic friction between a certain 15kg box and the floor is 0.35. How hard would you have to push on it to move it at the constant speed of 2.6m/s across the floor.
A 12 kg weather rocket generates a thrust of 250 N. The rocket, pointing upward, is clamped to the top of a vertical spring. The bottom of the spring, whose spring constant is 560 N/m, is anchored to the ground. What is the rocket's speed while the s..
Displacement d2 is in the xz plane 30° from the positive direction of the x axis, has a positive z component, and has magnitude 1.10 m.
A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.
A box slides down a ramp between a delivery area and soring area. You must determine the angle this ramp should have with the horizontal direction so that a 500 pound box takes 5.0 seconds to slide down the ramp starting from rest at the top. While t..
Jessica's weight is 540 newtons. According to the Third Law, if the Earth pulls on Jessica with a force of 540 N, then Jessica pulls on the Earth with a force of 540 newtons that acts in the opposite direction.though , if Jessica stumbles while rol..
