A force is applied to a toy car so that the car is moving toward the right but is slowing down at a steady rate( constant acceleration). Choose the force graph which could allow the describe motion of the car to continue. Assume friction is so small that it can be ignored.

Although light from the sun appears white, it is actually made up of a lot of different colors. this portion of the electromagnetic spectrum, we call white light is referred to as within the electromagnetic spectrum.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Need only answer if you think you know it
