White light strikes a diffraction grating (930 lines/mm) at normal incidence. What is the longest wavelength that forms a second-order maximum? I used the equation [(1/d)sin(90)]/m = wavelength: [(1/0.93m)(1)] /2 = 0.5376m. To convert to nm I multiplied b...

What is the probability that the bulb is glowing for a circuit set up as: |-------------(Bulb)-----------| | | | | (Voltage) | | | | | |----(Switch-1)---(Switch-2)---|

a fullback having a mass of 9.0x10^1 kg is running at 4.5 m/s [E]. He is hit by a linebacker and 1.2 s later is moving backwards at 1.5 m/s [W].Find: a) the impulse imparted to the fullback B) the average force exerted on the fullback by the linebacker my...

Apart at the end of one hour,what is the speed of each bus?

Terry hit his 26 g golf ball so that it has an initial velocity of 33 m s-1 travelling at an angle of 26 to the horizon. If the ball lands at the same height it was struck, how far will it travel? Use g = 9.8 m s-2.

Charlie now moved onto the next hole where he hit the ball with an initial speed of 30 m s-1 and at an angle of 60 degrees. This time the ball lands with a speed of 17.3 m s-1. Use g = 9.8 m s-2.

did you manage to solve it

no but how did you get it?
