Symbol help -- Mirrors & units question
Calculate to the nearest 0.1000 degree the diffraction angle of the first order image produced by monochromatic light of wavelength 5890.0 A as the light passes through a grating of 5500.0 lines/cm.
WHAT DOES THE SYMBOL 'A' MEAN??
My guess was 1^-10...
So it would be velocity=distance/time and it would be that simple because its uniform? And impulse=force*time?
It can't be that simple because that gives me a distance of 100 meters.
A 1,000kg car traveling with a velocity of +20.0meters per second decelerates uniformly at -5.00 meters per second per second until it comes to rest.
What is the total distance the car travels as it decelerates to rest?
What is the magnitude of the impulse applied to the car to bring it...
