Two lenses, one converging with focal length 20.5cm and one diverging with focal length ?10.5cm , are placed 25.0?cm apart. An object is placed 60.0?cm in front of the converging lens.
A) Find the final image distance from second lens. Follow the sign conventions.
B) Determine the magnification of the final image formed. Follow the sign conventions.
A fixed system of charges exerts a force of magnitude 9 N on a 3 C charge. The 3 C charge is replaced with a 10 C charge. What is the exact magnitude of the force
A 65kg person throws a 0.0410 kg snowball forward with a ground speed of 28.0 m/s. A second person, with a mass of 60kg, catches the snowball. Both people are on skates.
A coffee filter of mass 1.5 grams dropped from a height of 2 m reaches the ground with a speed of 0.7 m/s. How much kinetic energy Kair did the air molecules gain from the falling coffee filter? begin from the Energy Principle, and choose as the s..
A ranger in a national park is driving at 44 km/h when a deer jumps onto the road 70 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -3.00 m/s2.
A neutral (uncharged) capacitor has a charge of -3.00C moved from one of the plates to the other in a time of 5.00 sec, leaving +3.00C on the 1st plate. The +charges don't move, only the electrons. What was the average current?
A wheel has a radius of 3.6m. How far (path length) does a point on the circumference travel if the wheel is rotated by angles of 30°, 30 rad, and 30 rev, respectively.
A coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 2.00 cm and 1000 turns/meter. The current in the solenoid changes as I = (5.00 A) sin(120t). Find the induced emf in the 15-turn coil as a function of time.
What is the total work W_fric completed on the block by the force of friction as the block moves a distance 8 rm m up the incline.
The magnitude of the force of friction acting on the block between A and is 1.2N and points A and B are 0.5 m apart. If the kinectic energies of the block at A and B are 4J and 5.6 J, respectively, how much work is done on the block by the force p..
