Janice's pinky is 5.85 cm long. When she holds her pinky a certain distance from a spherical mirror, an inverted image 2.10 cm long is formed. When she moves her finger 1.20 cm closer to the mirror, the size of the inverted image increases to 3.00 cm. (a) Find the original distance between Janice's pinky and the mirror, and the focal length of the mirror. (b) Draw a ray diagram showing the formation of the image with Janice's pinky in the original position.

Tara is a long-distance runner. Her body weight is 65 kilograms. She recently realized that when she doesn’t eat appropriate amounts of carbohydrates while training, she becomes fatigued much more quickly. She is unsure of how to plan her meals around her workout. Focusing on meeting her carbohydrate requirements and using the guidelines in the chapter, plan both a pre-workout meal and a snack following her two-hour workout. Why would a registered dietitian advise an endurance athlete such as a...

A standard violin string is 32.8 cm long from the tuning peg to the bridge. When played open(without pressing a finger against the fingerboard), this string has a fundamental (lowest)frequency of 440 Hz. (a) What is the wavelength of the wave at this frequency? (Hint: the lowest frequency is alsothe longest wavelength that can produce a standing wave.) b. (b) What is the speed of the wave on the string? (Hint: this is not the speed of sound!)c. (c) How...
