A convex mirror has a focal length of magnitude 7.63 cm.
(a) If the image is virtual, what is the object location for which the magnitude of the image distance is one third the magnitude of the object distance? (Enter distance in cm from the front of the mirror. If the image is real, enter NONE.)
cm
(b) Find the magnification of the image.

The Hall voltage across a conductor in a 42mT magnetic field is 1.9mu V. When used with the equal current in a different magnetic field, the voltage across the conductor is 2.7mu V.
A steel wire of mass 0.400kg and length 0.640m supports a 102 kg block. The wire is struck exactly at its midpoint causing a small displacement. How long does it take the peak of this displacement to reach the top of the wire.
The sensor in the torso of a crash-test dummy records the magnitude and direction of the net force acting on the dummy. If the dummy is thrown forward with a force of 570N while simultaneously being hit from the side with a force of 2400-N, what f..
A bob of mass m = 0.300kg is suspended from a fixed point with a massless string of length L = 21.0cm, What tangential speed v must the bob have so that it moves in a horizontal circle with the string making an angle 24.0
After the ambulance passes, the observed frequency of the siren is 493 Hz. Conclude the ambulance's speeds from these observations.
Consider a dry air parcel at -12 degrees celsius and 450mb that descends adiabatically down to the surface where p=1000mb, Calculate the potential temperature at the surface
A unit of area, often used in measuring land areas, is the "hectare", defined as 104m2. An open-pit coal mine consumes 66hectares of land, down to a depth of 23m, each year. What volume of earth, in cubic kilometers, is removed in this time.
The Mini Cooper is rated at the maximum power of 115. hp (1 hp=746 W), when moving at 80km/h. Suppose that the net force accelerating the car is constant.
