Acar with a mass of 1.1 x 10^3 kilograms hits a stationary truck with a mass of 2.3 x 10^3 kilograms from the rear end. the initial velocity of the car is +22.0 meters/second. after the collision the velocity of the car is -11.0 meters/second. what is the velocity of the truck after this elastic collision? a.) +13 meters/second b.) +20 meters/second c.) 15.7 meters/second d.) +7.5 meters/second e.) +9.8 meters/second

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
