Answer:
(a)
(b)
(c)x = 30m, y = 25m
(d)11.66m/s
Explanation:
While position has a formula of , velocity has a formula of a*t.
(a) the vector position of the particle at any time t is
(b) the vector velocity of the particle at any time t is
(c) at t = 5 s
So x = 30 m and y = 25m
(d)
with So the speed quantity is
Answer:
gravity effects only the mass of an object
Explanation:
an acorn is heavier that a stick and it's round shape gives it less wind resistance so gravity pulls it down faster. A stick vertical has little wind resistance but when rotated to when it is horizontal it has more resistance so it slows down but the the force of gravity is still as strong. A leaf has very little mass and it's shape provideds lots of wind resistance so it falls slower. The moon is not only effected by the earth's gravity it is also effected by the suns. It has its own gravity as well. with all these factors it stays in place and moves with the earth.
<h2>Answer: The tsunami occurred on 1958 at Lituya Bay, Alaska.
</h2>
The Lituya Bay tsunami occurred on July 9th, 1958, northeast of the Gulf of Alaska. It was as a consequence of a strong earthquake of magnitude 8.3 on the Ritchter scale along the Fairweather Fault in the Alaskan Panhandle, which caused a landslide in a fjord in Lituya Bay, collapsing an entire mountain and generating a gigantic wave that rose to <u>524 meters</u>, the highest recorded so far.
It should be noted that despite its great magnitude and having uprooted all the trees and vegetation of the place, this mega-tsunami claimed only five lives because the area was not as inhabited as the large cities are.
