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.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
