Answer:Ef = 1/2 I ω2 (1)
where
Ef = flywheel kinetic energy (Nm, Joule, ft lb)
I = moment of inertia (kg m2, lb ft2)
ω = angular velocity (rad/s)
Explanation:
-- If there are only <em>10</em> elements in the universe that can make compound molecules, and a compound molecule can be formed by combining 1, 2, 3, or 4 different elements, then that's already the possibility of at least 400 different molecules.
-- There are many more than 10 elements that can combine to form compound molecules.
-- Every single "<em>organic</em>" molecule, of which there are thousands, is the combination of <em>carbon</em> with other elements.
-- Most all of the substances that can be distilled out of oil, including the paraffin waxes, the alcohols, gasoline, kerosene, butane, propane, octane, and natural gas, are made of just carbon, hydrogen, and oxygen, only with different numbers of each one.
-- Plastics, drugs, rubber, and DNA are examples of molecules that are made of <em>hundreds</em> of atoms.
Answer:
A pi bond
Explanation:
A pi bond is a type of covalent bond that results from the formation of a molecular orbital by the side-to-side overlap of atomic orbitals along a plane perpendicular to a line connecting the nuclei of the atoms.
Answer:
The minimum coefficient of static friction between the road and the car's tires is 0.816
Option "C"
Explanation:
Given;
velocity of the car, v = 40.0 m/s
radius of horizontal curve, r = 200 m
For a minimum coefficient of static friction between the road and the car's tires that will allow the car to travel at the given speed without sliding, centripetal force must equal frictional force.
where;
μ is the minimum coefficient of static friction
Thus, the minimum coefficient of static friction between the road and the car's tires is 0.816
Option "C"
