A 4.0-cm tall light bulb is placed a distance of 35.5 cm from a convex mirror having a focal length of -12.2 cm. Determine the image distance and the image size.
a) Determine the other characteristics of the image (i.e size, orientation, and whether it is real or virtual?
b) Draw a labeled diagram of the situation (approximately to scale and sketch two principal rays)
An 84.4-mH inductor and a 6.27-µF capacitor are connected in series with a generator whose frequency is 361 Hz. Determine the rms voltage across the inductor
Young’s double slit experiment is performed with blue-green light of wavelength 500 nm. The slits are 1.20 mm apart, and the viewing screen is 5.40 m from the slits. How far apart are two adjacent bright fringes? What is the angular separation of two..
A beam contains 3.6 x 105 doubly charged positive ions per cubic centimeter, all of which are moving north with a speed of 5.3 x 105 m/s. Find what is the magnitude of the current density
Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.6 kg· m2 and an angular velocity of +7.6 rad/s. Disk B is rotating with an angular velocity of -10.8 rad/s.
A car is moving at constant acceleration. At t=5 seconds its velocity is 8m/s and at t=8 seconds its velocity is 12 m/s. What is the distance traveled in that interval of time
a car travels at a constant speed around a circular track whose radius is 2.6 km. the car goes once around the track in
It is known that a cubical object made of cast aluminium 0.240 m on a side contains a hollow cavity also in the shape of a cube however of unknown dimensions. If the mass of the object is 36.3 kg, decide the length of each side of the interior cubica..
A ladder of length L = 2.5 m and mass m = 15.0 kg rests on a floor with coefficient of static friction ?s = 0.57. Assume the wall is frictionless. What is the minimum angle to keep the ladder from sliding
Another way of looking at the fact that all objects have wave-like properties is diffraction. At what speed should the student be moving in order to have signficant diffraction as she enters the door
A strong weightless rope has a mass m hanging from the middle of it, as shown. The tension force on each rope is 25 N, and the rope droops at an angle of 20.0°. How much mass is hanging from the rope?
A jet lands at 66.7 m/s, the pilot applying the brakes 2.44 s after landing. Find the acceleration needed to stop the jet
An 810 kg race car can drive around an unbanked turn at amaximum speed of 60 m/s without slipping. The turn has aradius curvature of 150 m. Air flowing over the car's wing exerts adownward-pointing force (called the downforce) of 11500 N on the ca..
