1. A 4.5-cm tall butterfly lands 65 cm in to the left of a converging lens of focal length of magnitude 25 cm. What can you say about the image that is formed?
The image is virtual, 2.5 cm tall, 30 cm on the right side of the lens.The image is virtual, 2.8 cm tall, 41 cm on the left side of the lensThe image is virtual, 2.0 cm tall, 15 cm on the right side of the lens.The image is real, 4.5 cm tall, 65 cm on the left side of the lens.The image is real, 2.8 cm tall, 41 cm on the right side of the lens.2. A Nd:YAG laser has a wavelength of 1064 nm in air. It enters some diamond with an index of refraction of 2.42. What can you say about the wavelength of the light in the diamond?

Determine the spring constant of the spring - compressing the spring to a maximum distance
At what angle of θ should the track be inclined so that a car traveling at 71.0 m/s (159 mph) would keep moving in a circle if there is oil on that section of the track, i.e., it would not slip sideways even with zero friction on that section. (Hi..
A 4700 μF capacitor is charged to a 9 Volt battery and then connected across a 1.50 H inductor. Evaluate what is the maximum current
Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 10oC at one end and 122oC at the other end. Compute the length the rods must have
Three students have been studying relative motion and decide to do an experiment to demonstrate their knowledge. If Fred throws the ball at this angle, how high does Sue observe it to travel above the level at which it was thrown
An unspecified force causes a 0.2-kg object to accelerate at 0.4 m/s2. find the acceleration (in m/s2) of the heavier object
The steam leaves the turbine at 0.5 MPa and 200°C with a velocity of 180 m/s. The rate of work done by the steam in the turbine is measured to be 20MW. Determine the rate of heat transfer associated with this process.
If the diameter of the fifth circular orbit of the hydrogen atom is 26.5 A, what is the frequency of the reveloution
Do sound waves exhibit diffraction effects? If so, determine the "slit" width that would diffract an audible sound wave (frequency between 20 Hz and 20 kHz). Would a doorway work or do you need a different sized opening?
