While we think that our planets formed through the process of core collapse, planets around other stars might or might not have formed from the process of disk instability. Which of the following would make disk instability MORE LIKELY to have occurred around a star? ---

A hotter disk of material

A more massive disk

A more massive star

A larger fraction of solid material in the disk

A previously formed planet

None of these would make disk instability more likely

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.
