Sig. gif?tid=2M68-7D-94-42-ABFD-18787 At the end of their lives, very massive stars explode in a supernova, which can be powerful enough to outshine the entire rest of thier host galaxy - around 5.0 × 1037 W. Suppose such a star is 950 times brighter than our Sun, which has a power of 4.0 × 1026 W, and suddenly goes supernova.

By what factor does the power of the massive star increase when it turns into a supernova?

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.
