Answer: g = acceleration = A*w^2 = A*(2*pi*fb)^2.
Explanation:
The ball bounces when the acceleration of the ball exceeds that of gravity. If A and fb are measured at that point, g = acceleration = A*w^2 = A*(2*pi*fb)^2.
Answer:
true cuase it is true its not false
Ke= 1/2 x m x v^2
Ke= 1/2 x 2.1 x 30^2
Energy = 945 J
<h3><u>Answer;</u></h3>
Continental accretion
<h3><u>Explanation;</u></h3>
- The collision and joining of crustal fragments to a continent is called the continental<em><u> </u></em><em><u>accretion</u></em><em><u>.</u></em>
- <em><u>Accretion is the process through which materials such as sediment, volcanic arcs, or seamounts or blocks, etc. are added to the tectonic plate or land mass.</u></em> Many astronomical bodies, such as stars, galaxies or planets are formed by this process.
- Where the process of accretion has occurred the tectonic plates may have dense basaltic rocks which are indicative of oceanic lithosphere.
This is because of the conservation of angular momentum, which allows most planets to spin in the same direction, but Venus and Uranus have seem to ignore this as they spin in different directions, as Venus spins clockwise and Uranus is on its side
