Suppose an electron is accelerated by an electric field between two plates, plate A and plate B. Assume the electron acquires 1.3E-16 J of kinetic energy in going from from plate A to plate B. How much is the difference in potential (in V) between the plates, V(B)-V(A)?
A beam of hydrogen molecules (H2) is directed toward a wall, at an angle of 68 ° with the normal to the wall. What is the beam's pressure on the wall
How does the solar nebula theory describe the dramatic density difference between the terrestrial and Jovian planets.
A copper rod 81 cm long is used to poke a fire. The hot end of therod is maintained at 105° C and the cool end has a constanttemperature of 24° C. What is the temperature in degrees Celsius of the rod 23 cm from the cool end?
A turtle ambles leisurely–as turtles tend to do–when it moves from a location with position vector r1,x = 1.97 m and r1,y = -2.35 m in a lettuce garden to another location, with position vector r2,x = 3.15 m and r2,y = -4.15 m, where the lettuce a..
A golf ball is dropped from rest from a height of 9.50 m. It hits the pavement, then bounces back up, rising just 5.50 m before falling back down again. A boy then catches the ball when it is 1.30 m above the pavement. Ignoring air resistance, cal..
