A college student who was late for his physics class drove through a red traffic light and was stopped by a patrolling policeman. He is trying to explain the policeman that the red light appeared green to him due to the Doppler effect.
How fast did he need to drive for a Doppler shift this large? (For red light use 677 nm, for green 540 nm as wavelength.)
Find the eight ball's speed after the colision. Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit with a width of 0.437 mm. What is distance from the central maximum to the first minimum on a screen 1.75 mm away f..
Consider two isolated, charged conducting spheres: a large sphere and a second smaller sphere with a radius 8 times smaller than that of the large sphere, but with 4 times as much charge.
What must be the mass m2 of the hanging block if it is to descend 11.0m in the first 3.00s after the system is released from rest
In the x-y plane, a point of +2.6 uC is on the x-axis at (-3 cm, 0), and a second point charge of -3.4 uC is also located on the x-axis, Determine the Work required (in keV) to move an electron from Pa to Pb
A 1.00uF capacitor is connected in parallel with a 2.00uF capacitor, Find the potential on the negative plate of the 1.00uF caacitor and the equivalent capacitance of the two capacitors
