The surface of the oil is illuminated from above at normal incidence with white light. What is the wavelength of light in the 400 nm to 800 nm wavelength range that is most weakly reflected?
Light from a laser beam with a wavelength of 530 nm passes through a narrow single slit and is observed on a screen 1.0 m behind the slit. The first minimum of the diffraction pattern is 0.84 m from
On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 4.80 times as far as he would have on earth, given the same initial velocities on both planets.
A jeweler needs to electroplate gold (atomic mass 196.97 u) onto a bracelet. He knows that the charge carriers in the ionic solution are gold ions, and has calculated that he must deposit 0.20 g of
A wind is blowing that results in a net horizontal force on the plane due to the air of 2.40 kN in a direction 10.0° south of west. How much work is done by the air on the plane?
An object begins at the origin. It first moves in a straight line to x = 1.00 m, y = 0.00 m. It then moves in a straight line to x = 1.00 m, y = 1.00 m. How much work is done on the object by the fo
A 30 N-force toward the west is applied to an object. The object moves 50 m east during the time the force is applied. What is the change in kinetic energy of the object?
A 3.00 kg mass is attached to this spring and released from rest after stretching the spring 2.00 m. What is the speed of the mass when the spring returns to its equilibrium length?
A constant force = 2.00 Ni + 3.00 Nj acts on a 5.00 kg object as it moves in a straight line from the position 1 = 1.00 m + 1.00 m to a position 2 = 4.00 m - 1.00 m . Determine the work done by the
A marble is thrown horizontally with a speed of 12.3 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 71 ° with the horizontal. From w
An airplane with a speed of 82.7 m/s is climbing upward at an angle of 31.8 ° with respect to the horizontal. When the plane's altitude is 871 m, the pilot releases a package. (a) Calculate the
The ball leaves the club at a speed of 18.7 m/s at an angle of 51.0? above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of
A tennis ball is struck and departs from the racket horizontally with a speed of 28.4 m/s. The ball hits the court at a horizontal distance of 19.4 from the racket. How far above the court is the te
A spacecraft is traveling with a velocity of v0x = 6150 m/s along the +x direction. Two engines are turned on for a time of 918 s.
The components of these variables are: vx = x component of the velocity vy = y component of the velocity ax = x component of the acceleration ay = y component of the acceleration Which of these comp

How does the force curve compare to the distance curve? What differences are there? What would you say is the relationship between force and position?
Assuming ideal gas behavior. Why is this process isothermal (T1=T2)? Derive equations justifying.
How does the acceleration curve compare to the force curve? What differences are there? From looking at a graph, what would be the relationship between force and acceleration?
When the mass has its maxiimum positive velocity, is its distance from the equillibrium position maximum, minimum, or some other value? What about when it reaches maximum negative velocity? Explain
The electron gun in a color TV accelerates the electrons through about 25,000 Volts. Estimate the force on such an electron due to the magnetic field of the earth. Hint: The Earth's magnetic field i
