In order to estimate the properties of a uniform magnetic field, you shoot an alpha particle into the field. The alpha particle has an initial speed of 1.5 107 m/s. The initial trajectory, moving horizontally from left to right, is set so that it will enter the magnetic field directly in front of you. After entering the field, the alpha particle moves in a counterclockwise orbit with a diameter of 30.8 cm in a vertical plane. What does this tell us about the field? (Alpha particles carry q = +2e charge and the mass is m = 6.6 10-27 kg) Determine the magnitude of the particle?
A 110 grams sample of water at 30 degrees Celcius is heat to steam at 130 degrees Celcius. how much heat is absorbed
A chair of weight 125 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 35.0 N directed at an angle of 42.0 below the horizontal and the chair slides along the floor. Using Newton's laws, compute..
