What best describes the greatest height a ball will bounce off the ground after being dropped from a height of 50 centimeters? (5 points)
A.) Less than 50 centimeters, as the ball transforms some of its thermal energy into
sound energy
B.) Less than 50 centimeters, as the ball transforms some of its potential energy into sound energy
C.) Greater than 50 centimeters, as the ball transforms some of its thermal energy into potential energy
D.) Greater than 50 centimeters, as the ball transforms some of its potential energy into thermal energy

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be. to test this hypothesis, you would change the gap widthdiffraction anglewavelength and observe the gap widthdiffraction anglewavelength in the system. therefore, the independent variable would be the gap widthdiffraction anglewavelength and the dependent variable would be the gap widthdiffraction anglewavelength.
