Force p is applied to the 67-kg block when it is at rest. determine the magnitude and direction of the friction force exerted by the surface on the block if (a) p = 0, (b) p = 236 n, and (c) p = 370 n. (d) what value of p is required to initiate motion up the incline? the static and kinetic coefficients of friction between the block and the incline are μs = 0.23 and μk = 0.20, respectively. the friction force is positive if up the incline, negative if down the incline.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

10 newton object is placed 3 meters from the fulcrum. at what distance on the other side would you need to place a 15 newton object to balance the lever? show your work!

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
