A rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid, as shown.

1 answer:

8 0

Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.

26. If it is noon, solar time, at 70°W longitude, what is the solar time at each of the following locations? 72 W longitude: 65°

Naddika [18.5K]

Answer:

If it is noon time at 70 degree west longitude, The solar time at 72 degree west longitude would be 12:08 p.m., at 65 degree west longitude time would be 11:40 a.m., at 90 degree west longitude the time would be 12:40 p.m. and at 110 degree east longitude the solar time would be 00:00 midnight. This has been calculated with the formula that one degree is equal to 4 minutes.

Which of the following is a domestic influence on foreign policy?

LenKa [72]

The correct answer is - A famine in Ireland prompts US response.

With the Irish famine of the 19th century, and the response to it by the United States, we have a very nice example of domestic influence on foreign policy.

Namely, the Irish potato famine was so bad, that very large percentage of the Irish population actually died, and the rest of the population was on the verge of starvation. Because of this, lots of people wanted to move out of the country in order to at least be able to have food on the table. This prompted a response from the United States, and they made an exception in their strict foreign policy because of the Irish people, so opened their borders to them in order to help them, thus letting them settle in the country.

Base your answer on the passage below and on your knowledge of Earth science.Island ArcsIsland arcs are long, curved chains of o

murzikaleks [220]

Answer:

"Island ArcsIsland arcs are long, curved chains of oceanic islands associated with seismic activity and mountain-building processes at certain plate boundaries. They occur where oceanic tectonic plates collide. Along one side of these island arcs, there is usually a long, narrow deep-sea trench.At island arcs, the denser plate is subducted and is forced into the partially molten mantle under the less dense plate. The islands are composed of the extrusive igneous rocks basalt and andesite. The basalt originates most likely from the plastic mantle. The andesite originates most likely from the melting of parts of the descending plate and sediments that had accumulated on its surface.Which list identifies minerals present in andesite from the greatest percentage by volume to the least percentage by volume? "
As the different situations and events gave rise to the seven different tectonic plates which comprises the over all structure of the planet, as there are a number of geological sites that took there shape because of the movement of the different planetary regions, layers, or the components which makes up the deep down trenches and the islands along with the different volcanic hotspots.
Mostly the subduction region is only due the movement or the sliding of the different tectonic plates which gives rise to a way different catastrophic events like the creation of the seismic way may generate the earth quakes inside the different regions.
Along, with that the different climates across the globe are also due the difference in such geological sites.
