A mass of m = 1 kg on a frictionless surface is observed to accelerate at a = 10 m/s2 at an angle of 60o east of north as shown in the top down view picture below. F2= 5 N and is directed directly upward. Determine the magnitude of F1 if it acts directly to the right.

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

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.
