An object is launched at a 27 degree angle at 49 m/s off a 55m tall cliff. What is the horizontal range of this projectile?

What are atoms of the same element with varying number of neutrons

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.
