The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. A typical amateur astronomer's telescope may have a 7.0 in. -diameter mirror.
A. What is the minimum angular separation (in arc seconds) of two stars that can be resolved with a 7.0 in. scope? (Take θ to be at the center of the visible spectrum, about 550 nm, and note that 1 arc sec = 1/3600 o)
B. What is the minimum distance (in km) between two points on the Moon's surface that can be resolved by a 7.0 in. . scope? (Note: The average distance from Earth to the Moon is 384,400 km.)
A jetliner is moving at a speed of 274 m/s. The vertical component of the plane's velocity is 54.0 m/s. Conclude the magnitude of the horizontal component of plane's velocity.
A test tube 105 mm long is held rigidly at 29° with respect tothe vertical in a centrifuge with its top lip 6.0 cm from the central spin axis of the machine. If itrotates at 43000 revolutions per minute, what is the centripetal acceleration of a ce..
A cardinal (Richmondena cardinalis) of mass 4×10-2 kg and a baseball of mass 0.143 kg have the same kinetic energy. What is the ratio of the cardinal's magnitude p_c of momentum to the magnitude p_b of the baseball's momentum.
A segment of wire carries a current of 25 A along the x axis from x = -2.0 m tox = 0 and then along the z axis from z =0 to z = 3.0m. In this region of space, the magnetic field is equal to 40 mT in the positive z direction. What is the magnitude of ..
What is the image distance? What is the x coordinate of the object? Keep in mind that a real image and a real object should be on opposite sides of the lens.
A mass m= 1kilogram is released from rest on a frictionless track at a height h=5 meter. Calculate by how much is the spring compressed at point B
A 3280 kg demolition ball swings at the end of a 17.1 m cable onthe arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 2.72 m/s. Determine the tension in the cable.
Determine the maximum magnetic flux through an inductor connected to a standard outlet (?Vrms = 120 V, f = 60.0 Hz)
Two tugs A and B pull a ship along a direction XO. Tug A exerts a force of 30kN at an angle of 15 degrees to XO, Find the angle X for the resultant force on the boat to be along XO
A skier of mass 50 kg is moving at speed 10 m/s at point P1 down a ski slope with negligible friction. What is the skier's kinetic energy
What happens to rechargable batteries in the process of recharging? What are some experiments you can do to test how batteries work?
A suspension bridge is 62.0 m above the level base of a gorge. A stone is thrown or dropped from the bridge. If you throw the stone straight down with a speed of 25.0 m/s, how long before it hits the ground
