Explanation:
Hello !
<h2>Archimedes' principle</h2>
''states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.''
Archimedes principle equation is given as
buoyant force = density of fluid x volume of displaced fluid x acceleration due to gravity. or
<em>Fb=-density*gravity*volume </em>
<em>For example,</em> a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight.
The answer a boulder has more mass and stuff like that.
Answer: 8 or 9
Explanation: they are so many ocean water in the world
The Linear speed of the CD is : 30.16 m/s
<u>Given data : </u>
Angular speed = 4800 RPM
Diameter of CD ( D )= 120 mm ≈ 0.12 m
<h3 /><h3>Determine the Linear speed of the CD </h3>
applying the equation : v = ( π DN ) / 60 m/s
Linear speed ( V ) = ( π * D * N ) / 60 m/s
= ( π * 0.12 * 4800 ) / 60
= 30.16 m/s
Hence we can conclude that the linear speed of the CD is : 30.16 m/s
