An astronaut in a space shuttle claims she can just barely resolve two point sources on Earths surface, 160 km below. Calculate their (a) angular and (b) linear separation, assuming ideal conditions.Take l ! 540 nm and the pupil diameter of the astronauts eye to be 5.0 mm.
Torque Torque ● The tendency of a force to rotate a body about some axis ● The same force will be a lot more effective at rotating an object such as a nut with a wrench, or a door opened at the handle instead of a hinge. ● The units of torque are: ○ [τ] = [r][F] = Nm Reformatting Newton’s Second Law ● τ = Iα More Torque ● τnet τ1+ τ2+ ... ● Counterclockwise...
