Ray Optics: Combination of lens and mirror

An object is placed 12.0 cm in front of a converging lens of focal length 5.00 cm. A concave mirror with radius of curvature 20.0 cm is located 30.0 cm in back of the lens as shown. (refer to attached picture) 1.) At what distance from the lens does the first image (from the lens) form? 2.) What is the magnification of the ...continues

Ultrasonic waves

Please answer all questions with full explanations 1) An ultrasound wave has frequency 100 kHz and wavelength (in air) of 3.5mm. What is the speed of these ultrasonic waves? 2) 3mm wavelength radar waves have speed 3.00 x 10(8) ms(-1) (as do all electromagnetic waves in air) what is their frequency? 3) Ultrasound is a l ...continues

Electromagnetic induction

(See attached file for full problem description with proper symbols and diagrams) --- 1. How fast would you have to move a 1.0 m long conductor to produce a motional emf of 1.0 V in a 4 x 10^ -4 T magnetic field (assume that the conductor moves perpendicular to the field)? If a resistance of 0.5 ohm is co ...continues

Circuits

1. Draw a circuit involving bulbs and a battery as follows: Bulb A and bulb B are in series. The A/B combination is in parallel with bulb C. The battery is in parallel with bulb C. Rank the bulbs in terms of brightness, from brightest to least bright. 2. Draw a circuit with bulbs and a battery as follows: Bulb A and bulb B a ...continues
