Explanation The basic assumption in the statistical approach is that each microstate is equally probable. Total there are 16 possible microstates. The number of macro states of at least two heads will be found from the given table. The number of macro states of getting 4 heads is 1, for getting 3 heads and 1 tail is 4 and for getting 2 heads and 2 tails is 6. So to get number of microstates of at least two heads will be 6 + 4 + 1 = 11 . The relative probability of a macro state occurring is the number of microstates that give the same macro state. Thus probability is 11 16

Hi! I need help with these calculations for part i and part k for a physics Diffraction Lab. We used a slit width 0.4 mm to measure our pattern.

Examine the data and % error values in Data Table 3 where the angular displacement of the simple pendulum decreased but the mass of the pendulum bob and the length of the pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the angular displacement of the pendulum bob, to within a reasonable percent error.

In addition to the anyalysis of the graph, show mathematically that the slope of that line is 2π/√g . Using the slope of your line calculate the value of g and compare it to 9.8.
