The formula for the rotational kinetic energy is
where I is the moment of inertia. This is just mass times the square of the perpendicular distance to the axis of rotation. In other words, the radius of the propeller or this is equivalent to the length of the rod. ω is the angular velocity. We determine I and ω first.
ω = 573 rev/min * (2π rad/rev) * (1 min/60 s) = 60 rad/s
Then,

Answer:
Explanation:Digestive juices secreted by various organs such as salivary glands in the mouth, stomach, liver and pancreas help in the process of digestion of food. Saliva secreted by the salivary glands in the mouth aids in the breakdown of starch present in the food to simple sugar
Electron, photon and proton carry momentum .
- De Broglie derived the relationship between the wavelength and momentum of matter. This relationship is known as de Broglie's relationship.
- De Broglie's relationship is given by
...(1) - Momentum is the product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.
Equation (1) can be written as 
where λ is known as de Broglie wavelength and p is momentum , h = Plank’s constant
For photon , the momentum is given by 
...(2) where c is the speed is the speed of light .
From equation (1) and (2) we can conclude that electron, photon and proton carry momentum .

Answer; the free encyclopedia. In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
