Suppose you drop a rockinto a darkwell and, using precision equipment, you measure the time for the sound of a splash to return. (a) Calculate the time required for sound to travel up the well, calculate the distance tothe water if the sound returns in 2.0000s. (b) Now calculate the distance taking into account the time for sound to travel up the well. The speed of sound is 332.00m/s in this well.​

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.
