An object is placed 2.0 cm from a converging lens with focal length 1.5 cm. A concave mirror with focal length 1.0 cm is located 7.5 cm to the right of the lens as shown in the figure. Note: The figure is not drawn to scale. Determine the location of the final image. Draw a diagram
A bullet is fired through a board 13.5 cm thick, with a line of motion perpendicular to the face of the board. If the bullet enters with a speed of 387 m/s and emerges with a speed of 163 m/s, what is its acceleration as it passes through the boar..
The scalar product of vectors and is +51.0. Vector has magnitude 9.00 and direction 28.0 west of south. If vector has direction 36.0 south of east, what is the magnitude of.
How will their speeds to relate to each other when they land? Ignore air resistance. Clarify with graph. Draw a graph and explain why it happens.
What is the least (non-zero) thickness for the air layer between two flat, and parallel, glass surfaces if the glass is to appear dark while 640 nm light is incident normally? What if the glass is to appear bright.
You find an unlabeled box of fine needles, and want to determine how thick they are. A standard ruler won't do the job, since all you can tell is that each needle is less than a millimeter thick.
What is the ratio of the cardinals magnitude. One mole of tungsten (6 1023 atoms) has a mass of 184 grams, and its density is 19.3 grams per cubic centimeter. You have a long thin bar of tungsten, 2.3 m long, with a square cross section, 0.15 cm on..
The ball is in equilibrium, with the thread making an angle of 30.0o with respect to the vertical. The area of each plate is 0.01381 m2. What is the magnitude of the charge on each plate?
A 300g ball on a 70-cm-long string is swung in a vertical circle about a point 200 cm above the floor. What was the tension in the string an instant before it broke
A ladder of length L = 2.4 m and mass m = 14 kg rests on a floor with coefficient of static friction ?s = 0.56. Assume the wall is frictionless. find the normal force the floor exerts on the ladder
W hat is the ratio of an amplitude of the damped oscillations
If, instead, the gold is drawn out into a cylindrical fiber of radius 1.5µm, what is the length of fiber.
A proton is initially at rest at a point where the potential is 455V. Sometime later the proton is at a point where the potential is 191V. If no force but the electrostatic force acts on the proton, what is its final kinetic energy.
