1- Determine the volume of the box and the block.
2- Determine the ratio of the block to the box:
volume of block = (L)(W)(H)
volume of box. (L)(W)(H)
2.1- Multiply this number by 100 to turn it into a percent.
2.2- Complete this statement: The volume of the block is percent of the volume of the box.
3- Determine the ratio of the number of hits to the number of shots:
number of hits/100 shots
3.1- Multiply this number by 100 to turn it into a percent.
3.2- Complete this statement: The block was hit percent of the time.
4- Compare the results of step 2 to the results of step 3. Are the percentages similar?
5- Write a conclusion discussing the following items:
5.1- Based on your findings, do you think Rutherford's hypothesis was reasonable?
5.2- Restate Rutherford's hypothesis and describe how you tested it.
5.3- State whether your results support the hypothesis. If they do not, can you suggest some error in experimental procedure (other than general human error) that might explain it?
5.4- Finally, explain how this experiment confirms the nuclear model of the atom and the idea that most of the atom is empty space.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive â and âdirections, respectively, and use â10 m/s2 for the downward acceleration due to gravity.

Dc versus ac problem. suppose your dc power supply is set to 15 v and the vertical setting on the oscilloscope is at 5 v/div. how many divisions will the trace deflect if you connect the output of the power supply to the scope with the a input switch set on dc? how many divisions if the switch is on ac?
