Q. A Ferris wheel with radius 14.0 m is turning about a horizontal axis through its center. The linear speed of a passenger on the rim is constant and equal to 7.81 m/s.
What is the magnitude of the passenger's acceleration as she passes through the lowest point in her circular motion?
What is the direction of the passenger's acceleration as she passes through the lowest point in her circular motion?
What is the magnitude of the passenger's acceleration as she passes through the highest point in her circular motion?
How much time does it take the Ferris wheel to make one revolution?
What is the wavelength of the waves emitted by source? What is the difference in frequency between directly radiated waves and the waves reflected from a whale travelling straight toward the ship at 4.99? Suppose that the ship is at rest in the water..
A broad beam of light of wavelength 485nm is incident at 90° on a thin, wedge-shaped film with index of refraction 1.50. An observer intercepting the light transmitted by the film sees 17 bright and 16 dark fringes along the length of the film. By..
Sketch a principle ray diagram showing the formation of the image. compute the position, size, orientation (erect or inverted), and nature (real or virtual) of the image.
A car dealer claims that his product will accelerate at a constant rate from rest to a speed of 200 km/hr in 8s. What estimated distance will the car travel.
A photon with a wavelength 4.40 scatters from an electron initially at rest. Find out the wavelength of the scattered photon when the scattered electron has its utmost kinetic energy. Kmax = 2.37*20^-14.
What is the final charge of each conductor. Two identical spherical conductors X and Y are mounted on insulated stands. X carries the charge of +8.0nC and Y carries a charge of -2.0nC.
A rectangular block of ice 9.00 m on each side and 0.7 m thick floats in sea water. The density of the sea water is 1025kg/m3. The density of ice is 919kg/m3. How high does the top of the ice block float above the water level.

The radius of Venus's orbit is 0.72 times that of Earth's orbit. How much stronger is the Sun's gravitational field at Venus than at the earth.
I once observed a woman on an airplane at night with a camera. As we flew low over Washington DC she was impressed with the view of the city lights in the dark. She stood back in the aisle and tried to take the picture by the window using her flash. ..
A violinist places her finger so that the vibrating section of a 1.20 g/m string has a length of 40.0 cm, then she draws her bow across it. A listener nearby in a 20 ^circ {rm C} room hears a note with the wavelength of 30.0 cm. What is the tensio..
