Atugboat tows a ship with a constant force of magnitude f1. the increase in the ship's speed during a 10 s interval is 3 km/h. when a second tugboat applies an additional constant force of magnitude f2 in the same direction, the speed increases by 18 km/h during a 10 s interval. how do the magnitudes of f1 and f2 compare? (neglect the effects of water resistance and air resistance.)

Suppose a diode consists of a cylindrical cathode with a radius of 6.200Γ10^β2 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.

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
