(a) If the converging lens in a slide projector has a focal length of 104.00 mm and the slide is located 109 mm from the lens, determine the distance from the lens to the screen.
-------------- m
(b) Determine the dimensions of the image of the slide, if the slide measures 25.0 mm wide × 34.0 mm high.
A golf ball is dropped from rest from a height of 8.30 m. It hits the pavement, then bounces back up, rising just 5.90 m before falling back down again, calculate the total amount of time that the ball is in the air
A computer disk is 8.0 cm in diameter. A reference dot on the edge of the disk is initially located at theta=45 degrees. The disk accelerates steadily for 0.50 s, reaching 2000 rpm, after those coasts at steady angular velocity for another 0.50 s.
Light of wavelength 500nm is incident normally on a diffracation grating. Determine the total number of primary maxima that can be observed in this situation

A 220 block on a 52 long string swings in a circle on a horizontal, frictionless table at 95.What is the speed of the block? What is the speed of the block.
Rank the vector combinations on the basis of their angle, measured counter clockwise from the positive x axis. Vectors parallel to the positive x axis have the angle of 0. All angle measures fall between 0 and 360.
A sound source emits sounds of frequency 210Hz that travel by still air at 340m/s. The listener moves at 75 m/s relative to still air toward the stationary source. What is wavelength of the sound between the source and the listener.
A 85 kg window cleaner uses a 14 kg ladder that is 5.9 m long. He places one end on the ground 3.4 m from a wall, find the angle (relative to the horizontal) of that force on the ladder
