Answer:
Explanation:
Given that
Volume flow rate ,Q= 1200 m³ each seconds
So we can say that
Q= 1200 m³ /s
From energy conservation
(Potential energy +kinetic energy ) at top = (Potential energy +kinetic energy ) at bottom
U₁+ KE₁ = U₂+ KE₂
ρ Q g h + 0 = 0 + KE₂
KE₂= ρ Q g h
For water ,ρ = 1000 kg/m³
KE₂=1000 x 1200 x 10 x 100 W ( take g= 10 m/s²)
KE₂=120 x 10⁷ W
Only three forth of the energy converted into electrical energy
Therefore power P
Solids-are molecules that are together at all times( unless changed by a liquid or gas)
liquid-are molecules that move around freely in 1 space but can be changed to solid or gas
gas- molecules that move around freely and can be hot or cold depending
plasma- a material that goes to forming a cell or a liquid without any structual particles
There you go!
The particles that move in orbits of the same radius have the same momentum.
<h3>
Orbital angular momentum:</h3>
A point particle's three-dimensional angular momentum is traditionally represented by the pseudovector r p, which is the cross product of the particle's position vector r (relative to some origin) and momentum vector, which in Newtonian physics is denoted by p = mv.
L = mr = mr²w is the particle's orbital angular momentum in units of magnitude. The part of the particle's velocity that is here perpendicular to the axis of rotation is designated as The right-hand rule indicates the direction of the angular momentum. In isolated systems, the angular momentum is conserved.
