Determine the minimum thickness of a soap film (n= 1.80) that will result in constructive interference of a specific red line with wavelength 610 nm.
What is the wavelength of the light in the glass
Assume that your reaction time is 0.50 s and that your car brakes with constant acceleration. How far are you from the intersection when you begin to apply the brakes? Illustrate what acceleration will bring you to rest right at the intersection?
A 500g ball swings in a vertical circle at the end of a 1.5-m-long string. When the ball is at the bottom of the circle, the tension in the string is 12N
Draw a motion diagram for the train. Assume that the train is moving toward the right and starts to slow down at t = 0. The separation of each dot represents an elapsed time of one second.
You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. Explain how much force must you exert to keep the pole motionless in a horizontal position
A block with mass m = 19.0 kg slides down an inclined plane of slope angle 17.8 ° with a constant velocity. It is afterwards projected up the same plane with an initial speed 1.35 m/s. How far up the incline would the block move before coming to rest..
In the 1950s, an experimental train that had a mass of 2.30 x 10^4 kg was powered across a level track by a jet engine that produced the thrust of 5.30 x 10^5 N for a distance of 504 m. unless otherwise directed, suppose that air resistance is neglig..
Two capacitors, C1 = 30 µF and C2 = 4.0 µF, are connected in parallel and charged with a 110 V power supply. Calculate the total energy stored in two capacitors
David is driving a steady 21 m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.20 m/s^2 at the instant as David passes.
What is the electric field strength at midpoint between two disks.What is the electric field strength a point on axis 5.0 cm from one disk between them.
Compute the volume charge density of the atmosphere, assuming it to be uniform between 300 and 450 m. (Hint: You may neglect the curvature of the earth. Why?)
A system consists of three particles with these masses and velocities: mass 3.2 kg, moving north at 3.0 m/s; mass 3.8 kg, moving south at 4.9 m/s, What is the total momentum of the system
