Two experiments are conducted to determine the mass of an object. -In Experiment 1, you place the object on an electronic balance and read the object's weight.
-In Experiment 2, you apply a constant force to pull the object along a horizontal surface, while using a motion detector to measure the object's speed as it is pulled.

All frictional forces for both experiments are considered to be negligible. Which of the two experiments, if either, could be used to determine the gravitational mass of the object?

a. Experiment 2 only
b. Experiment 1 only
c. Neither experiment
d. Both experiments

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.
