Answer:
ugmd = 1/2 kx²
d = (1/2 kx²) / (ugm)
= (1/2 * 250 N/m * (0.2 m)²) / (0.23 * 9.81 m/s² * 0.3 kg)
= 7.4 m
ugmd = 1/2 mv²
v = √2ugd
= √(2(0.23)(9.81 m/s²)(7.4 m)
= 5.8 m/s
Explanation:
The movement of tectonic plates can cause earthquakes. Some can be major and some can be minor. Both can affect non-earthquake proof buildings though
Answer:
sure, do you have more detailed of the assignments...?
Explanation:
I think the correct answer from the choices listed above is the first option. The statement that best describes the state of metals when they are at room temperature would be that most <span>nonmetals are gaseous, but some are liquid or solid. Hope this answers the question. Have a nice day.</span>
The estimation of the age of the Earth comes from scientists who studied the rock formation under the Earth's crust. They believe that during the Big Bang, the Earth, together with the other celestial bodies in the universe, were formed. Under the Earth's soil contain radioactive materials that have known decay rates. Using these rate, they undergo tests like rock dating to find the time of its existence.
