Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27e-25 kg. The ions are accelerated from rest through a potential difference of 1.10 kV. Then, a 0.410 T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
A uniform pole is propped between the floor and the ceiling of a room. The height of the room is 8.00 ft, and the coefficient of static friction between the pole and the ceiling is 0.569. What is the length of the longest pole
Consider a homemade capacitor, which consists of 2 8.5" x 11" aluminum foil sheets separated by 10 sheets of paper. Estimate the capacitance of this device. What effect does the paper have on the capacitance
The voltage drop along a 30.0m segment of a power line made from copper wire (a very good conductor) is 1.2V, while carrying a current of 25.0 A. How large is the electric field along the wire
A 75-kg person sits on a 3.7-kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.5 cm in diameter. Find out the pressure exerted on the floor by each leg of the chair; assume the weight is evenly distributed.
An ideal fluid flows at 12 m/s in a horizontal pipe. If the pipe narrows to half its original radius, what is the flow speed in the narrower section
A 0.250 kg block is placed on a vertical spring (k = 5.0 x 10^3 N/m) and pushed downward, compressing the spring 0.10 m. As the block is free, it leaves the spring and continues to travel upward. What height above the point of release would the bl..
A large parallel plate capacitor has plate separation of 0.85 cm and plate area of 391 cm2. How much work is done on the capacitor as the plate separation is increased to 1.70 cm
If the bullet leaves the gun at a speed of 280 m/s, by how much will it miss the target? Illustrate at what angle should the gun be aimed so as to hit the target?
The initial angle of the ball’s motion off the tee is 29.0° above the horizontal. If the tee level is 17.0 m above the level of the fairway, explain how far east of the tee does the ball hit the fairway?
