A converging lens (f = 14.6 cm) is located 31.4 cm to the left of a diverging lens (f = -7.91 cm). A postage stamp is placed 47.1 cm to the left of the converging lens.
(a) Locate the final image of the stamp relative to the diverging lens.
(b) Find the overall magnification.
A 20.00 kg wood ball hangs from the 1.10 long wires. The maximum tension the wire can withstand without breaking is 600 N. A 0.710 kg projectile travelling horizontally hits and embeds itself in the wood ball. What is the largest speed this projectil..
A projectile of mass 7 kg is fired with an initial speed of 193 m/s at an angle of 16? with the horizontal. At the top of its trajectory, projectile explodes into two fragments of masses 4 kg and 3 kg.
The force on a particle is directed along an x axis and given by F = 0.97(x/4.6 - 0.52) where x is in meters and F is in Newtons. Find out the work done by the force in moving the particle from x = 0 to x = 8.9 m.
A person is standing at the edge of the water and looking out at the ocean (see figure). The height of the person's eyes above the water is h = 1.8 m, and the radius of the Earth is R = 6.38 x 106 m. (a) How far is it to the horizon? In other word..
