600 nm light is shined on a single slit which is 0.1mm wide. A diffraction pattern is seen on a screen 2.0m from the slit. What is the width of the central maximum?
Record the resistance and current values calculated in questions 5, and load the numbers into a spreadsheet. Make a plot of the current I as a function of the total resistance R. (Remember that the R values will go on the x-axis and the I values o..
At t = 0, an automobile travelling north begins to make a turn. It follows one-quarter of the arc of a circle of radius 10.70 m until, at t = 1.60s, it is travelling east. The car does not alter its speed all through the turn.
When in deep space, the block accelerates at 4.2 m/s^2 even as a 120 N force is applied to it. The coefficient of static friction for a particular plane and this block is 0.31. What angle can this plane make with horizontal before the object starts t..

Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Lastly, sphere C is touched to sphere B and separated from it. Explain how much charge ends up on sphere C?
A string of mass 0.0003kg/m and 0.5m long is vibrating 200 cycles per second. What must be the tension? What hanging mass would generate this tension? I got 12N for tension. Is this correct? And how would you solve for hanging mass.
