You want to pull the magazine 5-th from the top out of a stack of approximately identical magazines, each of mass 289.74 grams. Assuming you manage this without knocking the stack over, what force (in N) would you have to apply to begin pulling the magazine out if the coefficient of static friction between any pair of magazine surfaces is 0.56

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.

(a) if the pressure in gas is doubled while its volume is held constant, by what factor do (i) vrms and (ii) change? (b) is it possible to boil water at room temperature (20oc) without heating it? explain.
