Red light has a wavelength of 700. nm illuminates a slit of width 0.750 mm. The slit is 1.58 m from a screen. Where is the first minimum in the diffraction pattern on the screen relative to the center of the central maximum?

A. 1.1.47x10-3 m
B. none of the choices
C. 1.07x10-3 m
D. 1.58 m

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.
