Suppose you have a mass hanging from a spring scale and you are riding in an elevator. Upon reaching the 5th floor, your scale lurches to a higher reading
before returning to the resting weight. You could have been coming from

A. The first floor
B. The ninth floor
C. Any floor, impossible to tell without more information.
D. This scenario is impossible, scale readings will not change because your mass and
weight are constant.

The mass of a bowling ball is 10 kg and the mass of a ping pong ball is 0.015 kg. if the two objects are 5 meters apart, what is the gravitational force ?

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.
