A laser beam with a wavelength of 524 nm is exactly perpendicular to a screen having two narrow slits spaced 0.150 mm apart. Interference fringes, including a central maximum, are observed on a viewing screen 1.05 meter away. The direction of the laser beam is then slowly rotated by 1.00 degree around an axis parallel to the slits until it makes an 89.0 angle with the screen.
A duck flying horizontally due north at 14.8 m/s passes over Atlanta, What is the magnetic force acting on the duck
Must show all work!!! A block of mass m =.5kg is pushed against a wall with a force p = 4n orientated at an angle of 50 degrees. find the coefficient of static friction between the block and the wall
A simple Pendulum has a mass of 2.00 kg. The mass has a speed of 3.00 m/s, What is the maximum height (from the lowest position) the pendulum will reach
a race car is traveling at a constant speed v 200 mph over a circular banked turn. let the weight of the car be w
A block starts from rest at the top of a 35° inclined plane and encounters a spring, of constant 6.4 kN/m, rigidly attached to the plane. find the distance the block travelled before it encountered the spring
A magnetic field is oriented at an angle 42 degrees to the normal of a rectangular aread 5.5 cm by 6.8 cm. evaluate the strength of the magnetic field
when the pressure on saturated liquid water is suddenly reduced to a lower pressure in an adiabatic and aergonic
Two speakers, 6.00 m apart, are driven by the same audio oscillator so that each one produces a sound consisting of two distinct frequencies, 1000 Hz and 1360 Hz. The speed of sound in the room is 350 m/s.
A rectangular loop with dimensions 4.20 cm by 9.50 cm carries current I . The current in the loop produces a magnetic field at the center of the loop that has magnitude 3.40×10?5 T and direction away from you as you view the plane of the loop.
The nucleus 60Co decays by the emission of an electron ( B 2). (Energetic gamma rays also accompany this decay and are used for the treatment of cancer.) What is the resulting nucleus
Calculate the deBroglie wavelength of electrons that have been accelerated by 50,000 Volts (Remember the relation between energy and momentum). The answer is 5.486*10^-12 meters, but I'm not sure how to get it.
Two identical parallel-plate capacitors, each with capacitance C, are charged to potential difference ?V and then disconnected from the battery. Find the potential difference across each capacitor after the plate separation is doubled
