Particles pass through a single slit of width 2.0 mm (see Figure 29.15). The de Broglie wavelength of each particle is 490 nm. After the particles pass through the slit, they spread out over a range of angles. Assume that the uncertainty in the position of the particles is one-half the width of the slit, and use the Heisenberg uncertainty principle to determine the minimum range of angles.
A 1 mL syringe has an inner diameter of 4.0 mm, a needle inner diameter of 0.220 mm, and a plunger pad diameter (where you place your finger) of 1.20cm.
Calculate the y-component of the magnetic force.

The specific heat of ice to is 2100 and the heat of fusion for ice is . How much time passes before ice starts to melt? From the time while the heating begins, how much time does it take before the temperature begins to rise above 0.
A string with a mass of 31 g and a length of 2 m is stretched under a tension of 67 N. How much power must be supplied to the string to generate a traveling wave that has a frequency of 51 Hz and an amplitude of 4 cm?
Point A is located 0.259 m away from a charge of -2.11 x 10-9 C. Point B is located 0.487 m away from the charge. What is the electric potential difference VB - VA between these two points.
A wheel of diameter 5.8 cm has a 4 m cord wrapped around its periphery. Starting from rest, wheel is given a constant angular acceleration of 4.9 rad/s2. How much time it will take for the cord to unwind.
The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is θ = 0.320 rad. From these data, evaluate the speed of the bullet.
