An electron with a speed of 1.6 × 107 m/s moves horizontally into a region where a constant vertical force of 5.0 × 10-16 N acts on it. The mass of the electron is 9.11 × 10-31 kg. Determine the vertical distance the electron is deflected during the time it has moved 40 mm horizontally.
A very thin sheet of plastic (n=1.65) covers one slit of a double-slit apparatus illuminated by 640nm light. What is the (minimum) thickness of the plastic
The mass of Mercury is 0.0550 times that of earth, and its radius is 0.380 times that of earth, Calculate the average density of Mercury (in kg/m3) given the earth's density is 5.52×103 kg/m3
A 0.20-kg object is attached to the end of an ideal horizontal spring that has a spring constant of 120 N/m. compute the amplitude A of the motion
Young's Double Slit Experiment is performed with 589 nm light and a distance of 2.00 m between the slits and the screen. The fifth interference minimum is observed 7.50 mm from the central maximum. Resolve the spacing of the slits.
A small boat is moving at a velocity of 3.35 m/s while it is accelerated by a river current perpendicular to the initial direction of motion. If current acceleration is 0.750 m/s^2, what will the new velocity of the boat be after 33.5 s.
A charge of -5 micro-coulombs is placed at x = 0 cm, y = 0 cm. Another charge of -5 micro-coulombs is placed at x = +22 cm, y = -50 cm. When measured counter-clockwise from the x axis, what angle is the electric force vector acting on the charge a..

A group of hikers hear an echo 2.50 s after they shout. If the temperature is 28°C, how far away is the mountain that reflected the sound wave.
A 5000 kg truck moving right at 20 m/s collides and sticks to a 2000 kg car moving left at 10 m/s. If momentum is conserved, then what is the velocity after the collision
Consider two widely separated conducting spheres, 1 and 2, the second having four times the diameter of the first. What is the ratio of the final surface charge density of spheres
A 0.200 kg block is placed on a vertical spring (k = 5.00x10^3) and pushed downward, compressing the spring 0.100 m. As the block is free, it leaves the spring and continues to travel upward. What height above the point of release would block reac..
