A mirror has a focal length of 10 cm. An object is located 15 cm to the left of the mirror.
1. Draw the ray diagram for this set-up.
2. Where is the image located?
3. Is the image real or virtual?
4. What is the magnification of the image?
5. If now a lens of focal length 20 cm is placed 20 cm to the left of the mirror, find the locations of the images formed?
6. What is the total magnification for the two images?
7. Describe the images, ie are they real or virtual, upright or inverted?

At pH=7, do you expect the following peptides to bind a cation exchanger or an anion exchanger resins
In programming, a precise definition of the input; how the system should behave and how the output should be produced is known as:
assume the roller coaster (h1 = 37 m, h2 = 13 m, h3 = 30) passes point A with a speed of 3.10 m/s. If the average force of friction is equal to one third of its weight, with what speed will it reach point B? The distance traveled is 55.0 m.
While running, a person dissipates about 0.60 J of mechanical energy per step per kilogram of body mass. If a 64 kg person develops a power of 65W throughout a race, how fast is the person running? Assume that a running step is 1.5 m long.
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1020 Hz. The bird-watcher, however, hears a frequency of 1060 Hz. What is the speed of the bird, expressed as a percentage of the speed of sound?
Illustrate what is the absolute pressure at a point that is 9.82 cm below the ethyl alcohol-mercury interface?
Light from the sun is incident on the surface of a pond with a smooth surface. The light strikes the surface at the angle of 30 to the surface and is partially reflected. What is the angle of reflection for the reflected portion? What is an angle of ..
Find the radius of the largest water drop
Mr. Physics drops a rock down a 250-meter deep well. Upon impact with the bottom of the well a short burst of sound is produced with a frequency of 250 Hz. How long after he drops the rock does he hear it hit bottom of the well.
A certain car is capable of accelerating at a rate of 0.63 m/s2. How long does it take for this car to go from a speed of 56 mi/h to a speed of 60 mi/h.

compute the linear speed due to the Earth's rotation for a person at a point on its surface located at 40o N latitude (this would be near the Ohio river valley, for instance). The radius of the Earth is 6.40 ξ 106 m. (For comparison, the speed of ..
The only force acting on a 2.7 kg canister that is moving in an xy plane has a magnitude of 2.7 N. The canister initially has a velocity of 3.0 m/s in the positive x direction, and some time later has a velocity of 7.4 m/s in the positive y direct..
In the figure, suppose that the separation between speakers A and B is 5.90 m and the speakers are vibrating in phase. They are playing identical 110-Hz tones, and the speed of sound is 343 m/s.
