Calculate the acceleration of an electron that moves through the same magnetic field as in the example, as the same velocity as the proton. The mass of an electron is 9.11* 10^-31 kg. aelectron = m/s2.
Two identical masses are in a hemispherical bowl of radius R. One block is sitting at the bottom and the other is at the top. how high will each of them rise
A 140-m-wide river flows due east at a uniform speed of 3.9 m/s. A boat with a speed of 7.8 m/s relative to the water leaves the south bank pointed in a direction 39o west of north. How long does it take for the boat to cross the river
A copper rod (length=2 m, radius=3×10-3 m) hangs down from the ceiling. A 9.0-kg object is attached to the lower end of the rod. The rod acts as a "spring," and the object oscillates vertically with small amplitude. Ignoring the rod's mass, determ..
Compute the linear momentum and angular momentum of a Frisbee of mass 0.166 kg if it has a linear speed of 2.75 m/s and an angular velocity of 47.5 rad/s
A current of 10^-14 A is produced in a free-air chamber operating under saturation conditions. The sensitive volume, in which electronic equilibrium exists, contains 0.22g of air. What is the exposure rate .
Two identical guitar strings are prepared such that they have the same length (1.91 m) and are under the same amount of tension. compute the wave propagation speed on the guitar strings
