A typical atomic polarizability is 1×10-40 C · m/(N/C). If the q in p = qs is equal to the proton charge e, what charge separation s could you produce in a typical atom with applying a large field of 3×106 N/C, which is large enough to cause a spark in air?
a circular conducting loop with a radius of 1.0m and a small gap filled with a 10.0ohm resistor is oriented in the xy-plane. what is the magnitude of the current that will be caused to flow in the conductor

You sing into a well and find that the well resonates at frequencies of 187 Hz and 221 Hz with no resonances between these two frequencies. What is the frequency of the fundamental mode
A beam of hydrogen molecules, H2, is directed toward a wall, at an angle of 60° with the normal to the wall. What is the beam's pressure on the wall
A projectile is fired horizontally from a gun that is 48.0 m above flat ground, emerging from the gun with a speed of 280 m/s. How long does the projectile remain in the air
In a performance test, each of two cars takes 9.40s to accelerate from rest to 25 m/s. Car A has a mass of 1288 kg, and car B has a mass of 1767 kg. Find the net average force that acts on (1) car A and (2) car B during the test.
