Answer:
Explanation:
Work done on the lever ( input energy ) = force applied x input distance
= 24 N x 2m = 48 J
Work done by the lever ( output energy ) = load x output distance
= 72 N x 0.5m = 36 J
efficiency = output energy / input energy
= 36 J / 48 J
= 3 / 4 = .75
In percentage terms efficiency = 75 % .
Answer:
b racism bc saying whites are better than blacks is racist
Among the choices above, the one
that is most closely related to an activated complex is the transition state. The
answer is letter D. This formation forms quickly and does not stay in a way
compound is. It usually forms during the enzyme – substrate reaction.
Either it don't have a magnetic field around them or it's not a sheet steel door
Studying the structure of atoms and its sub-atomic particles is very important so that we could figure out a way on how to use our knowledge on it efficiently. Nuclear energy is one of the most powerful energies that needs to be properly harnessed and with adequate knowledge of the nuclear reactions, we could prevent nuclear disasters.
