Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together. Part of Hall of the Universe. The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. ... In a similar manner, moons formed orbiting the gas giant planets. Hope this helps!
Surveying encompasses every aspect of land, property and construction and offers a wide variety of career options. <span>There are many types of disciplines in surveying and a surveyor during their career may decide to specialize in a particular discipline or may gain experience in all disciplines.</span>
Th answer you are looking for is physical weathering
Answer:
15 inches
Explanation:
James needs to use the Pythagoras theorem, which states that in a right-angle triangle, the sum of the squares of the other two sides is equal to the square of the hypotenuse.
c²=a²+b²
we know that a is 9 inches and that be is 12 inches
c²= (9)²+(12)²
c²= 81+144
c²=225
c=√225
c=15
after applying the measures to the Pythagoras theorem formula,
we found out that the length of the straight-edge needs to be 15 inches
