A liquid at 25°c is poured at the height of 40cm in a thin capillary tube of length 70cm and diameter of 1 cm. Assume that volume of the capillary tube does not change with the temperature. a) Find the initial volume of the liquid in cm^3.
b) The temperature of the liquid is reduced by 10°c causing the liquid to reduce in height to 73cm. Find the volume coefficient of the thermal expansion of this liquid.
c.) At the initial height of 40cn and temperature of 25°c, what change in temperature is needed for the liquid to rise to a height of 49cm?

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.
