At the instant a traffic light turns green, a van that has been waiting at the intersection starts ahead with a constant acceleration of 2.00 m/s2. At that moment a truck traveling with a constant velocity of 15.0 m/s overtakes and passes the van.
a. Find the time necessary for the van to reach the truck.
b. Find the distance beyond the traffic light that the car will pass the truck.
c. Find the speed of the van when it passes the truck.
The threshold of dark-adapted (isotopic) vision is 6.0 multiplied by10-11 W/m2 at a central wavelength of 450 nm. If light with this intensity and wavelength enters the eye when the pupil is open to its maximum diameter of 8.5 mm, how many photons pe..
A charged belt, 50 cm wide, travels at 30 m/s between a sourceof charge and a sphere. The belt carries charge into the sphere ata rate corresponding to 100 μA. Compute the surface chargedensity on the belt.
An equilateral glass prism is to be designed so that a light beam entering the prism perpendicular to the first face will be totally internally reflected once off the second face
A laser beam moves from the bottom of an aquarium towards the surface. The beam describes an angle of 48.75 degrees fromthe normal measured at the surface. (The laser is not in thetank, it's below the tank and the bottom of the tank is made ofglas..
