Light with Wavelength 560 Nm Is Incident On A Diffraction Grating With Slit Spacing 2.0x10-6 M. Determine the angles at which all the bright spots in the diffraction pattern appear

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Consider an ideal gas at 27.0 degrees celsius and 1.00 atmosphere pressure. imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube. what is the length l of an edge of each small cube if adjacent cubes touch but don't overlap?

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?
