Question 3 (11 pts) Assume the distance I1 to I1' to be 40.0 cm and the distance G to O to be 40 meters. If the grating has 1600 lines/cm, what is the wave length of light that formed I1

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

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
