What is the mechanical efficiency of a machine whose work input is 100 J and work out put is 30 J?
The mechanical efficiency can be calculated using the formula: Efficiency = (Work output / Work input) * 100%. Given the values, we have: Efficiency = (30 J / 100 J) * 100% = 30%. Therefore, the mechanical efficiency of the machine is 30%.
Whose theory of light was correct?
Isaac Newton's theory that light is composed of particles called corpuscles was later proven to be incorrect. James Clerk Maxwell's theory that light is an electromagnetic wave was ultimately validated by experiments and is accepted as the correct explanation for the nature of light.
Whose theory brought in a transition from classical physics to modern physics?
Albert Einstein's theory of relativity, proposed in the early 20th century, was a key contribution that brought about a transition from classical physics to modern physics. This theory revolutionized our understanding of space, time, and gravity, leading to new ways of approaching physical phenomena.
Whose statement declares there can be no perfect heat engines?
The statement that there can be no perfect heat engines is declared by the Second Law of Thermodynamics. This law states that it is impossible for any heat engine to have 100% efficiency in converting heat into work.
Who was the scientist whose hypothesis on the wave nature of particles help lead to the theory of atomic structure?
Louis de Broglie was the scientist who proposed the hypothesis of wave-particle duality. This idea helped to further the development of the theory of atomic structure, particularly in understanding the behavior of electrons within atoms.
How would you prove that a certain theory is not acceptable?
By performing experiments whose goal is to prove that such theory is a mistaken theory.
Whose theory stated that a nations power is measured by its gold reserves?
Economic Theory
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
Whose theory of the criminal man was first important positivist theory to emerge?
Cesare Lombroso
Whose theory focused on population size?
Thomas Malthus!
Whose theory is household theory?
I Have a feeling that it was Durkheim, as he has alot to do with family and comes up alot when looking at theories.
Whose theory did chargaff disprove?
He disproved Phoebus Levene's theory that DNA was composed of a large number of repeats of GACT.
If compression ratio is samethen whose efficiency will be greater diesel cycle or otto cycle?
Diese
Whose improvements to the steam engine helped bring about the Industrial Revolution?
James Watt
Whose theory was that organisms can modify their bodies through the use or disuse of parts and that these modifications can be passed on to their offsprings?
Part of Lamark's theory.
Whose Atomic theory states that atoms are featureless and solid?
That was the earliest version of atomic theory, proposed by the Greek philosopher Democritus.Democritus
Darwin's theory what happens to individuals whose characteristics are not well suited to their environment?
No
