Suppose a 5.0 meter diameter telescope were constructed on the dark side of the moon. The viewing there (except for brief periods of sunlight) would be excellent. As an example, what would be the separation between two objects that could just be resolved on the planet Mars in 500nm light? [The distance to Mars at closest approach is 50 million miles]
A tank of water 3.00m deep sits on a table 1.00 m tall. A hole is located 2.0m from the bottom of the tank. Water flows out of hole and strikes the ground. Where does it strike the ground.
A string is attached to a rigid support and the cylinder allowed to drop from rest. Find out the acceleration of the cylinder.
what is the difference in blood pressure (mm-Hg) between the top of the head and bottom of the feet of a 1.84m tall person standing vertically
The lens of an endoscope is carefully matched such that the light ray from the edge of the lens enters the fiber at an angle. What focal length should the lens have
The light source for a double slit experiment has a wavelength of 590 nm. The slit separation is 0.12x10^-3. A screen is placed at a distance of L from the slits. Find the width of the central bright fringe
On a humid day, an electric field of 2.00 * 10^4 N/C is enough to produce sparks about an inch long. Suppose that in your physics class, use Coulomb's law to calculate the electric field at the surface of the sphere
A uniform stick d = 1 m long with a total mass of 249 g is suspended vertically from a frictionless pivot at its top end. A wad of putty of mass 26 g is moving horizontally with speed v. It strikes and sticks to the stick at a distance 0.75 m from..
A room measures 2.0 m by 5.5 m by 5.0 m. The heating and air-conditioning ducts to and from the room are circular with diameter 0.23 m, What is the necessary flow speed in the duct
A 58 kW radio station broadcasts its signal uniformly in all directions. What is the average intensity of its signal at a distance of 290 m from the antenna
A 5.00-g bullet, traveling horizontally with a velocity of magnitude 490 m/s, is fired into a wooden block with mass 0.800 kg, initially at rest on a level surface. What is the decrease in kinetic energy of the bullet
A 2.93-kg model rocket is launched vertically upward with sufficient initial speed to reach a height of 3.71·102 m, even though air resistance (a nonconservative force) performs -6.11·102 J of work on the rocket.
Suppose the force acting on a tennis ball (mass 0.040 kg) points in the +x direction and is given by the graph of Fig. 7-30 as a function of time. a) Use a graphical method to estimate the total impulse given the ball.
