A mass 
is connected by a light string that passes over a pulley of mass M to a mass 
sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of 1?2 
If 
is 1.00 kg, m2 is 2.00 kg, and M is 4.00 kg, then what is the tension in the string attached to 
?
A. 6.83 N
B. 7.03 N
C. 7.84 N
D. 8.02 N
E. 8.33 N
C. 7.84 N

Camera Exposure: A lens of focal length 45 mm is mounted on a 35-mm camera. The lens aperture is set at f/2.0 and the shutter speed set at 1/2000 s. The photographer wants to keep the same exposure (amount of light), but wants to change the f-number to f/8.0 for greater depth of field. What should be the new shutter speed to maintain the same exposure?
A. 1/1000 s B. 1/500 s C. 1/4000 s D. 1/8000 s E. 1/125 s
What do halo stars do differently from disk stars?
A) Halo stars orbit the galactic center with many different inclinations, while disk stars all orbit in nearly the same plane. B) Halo stars remain stationary, quite unlike disk stars that orbit the galactic center. C) Halo stars explode as supernovae much more frequently than disk stars. D) Halo stars orbit the center of the galaxy at much lower speeds than disk stars.
Which type of star has the strongest stellar winds?
A) giant K- and M-type stars B) white dwarfs C) dwarf K- and M-type stars D) main sequence O- and B-type stars E) T Tauri stars
A 3.0-kg mass is released from rest at point A of a circular frictionless track of radius 0.40 m as shown in the figure. The mass slides down the track and collides with a 1.4-kg mass that is initially at rest on a horizontal frictionless surface. If the masses stick together, what is their speed after the collision?
A. 2.1 m/s B. 1.7 m/s C. 1.9 m/s D. 1.5 m/s E. 2.3 m/s
