A stamp collector views a 1.5 cm tall stamp through a magnifying glass. The magnifying glass is a converging lens with a focal length of 15 cm. The stamp is 3 cm below the lens. (a) Sketch a ray-tracing of this situation. (b) Where is the image of the stamp located? (c) What is the magnification of the stamp? (d) How large will the image of the stamp appear to be?
A proton travels with a speed of 3.00 ? 106 m/s at an angle of 55.0° with the direction of a magnetic field of 0.520 T in the +y direction. determine the magnitude of the magnetic force on the proton
An airplane is dropping bales of hay to cattle stranded in a blizzard on the Great Plains. The pilot releases the bales at 140m above the level ground when the plane is flying at 80.0m/s 45.0 degrees above the horizontal. How far in front of the catt..
Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). Estimate the average bulk modulus of Earth's crust given
A 80-g bullet is fired from a rifle having a barrel 0.582 m long. Choose the origin to be at the location where the bullet begins to move. Then the force (in newtons) exerted by the expanding gas on the bullet is 14100 + 9100x - 24250x2, where x is i..
