Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain? It is not possible for a engine to operate without rejecting any waste heat to a low temperature reservior. It violates the second law of thermodynamics, the operation of a heat engine a low temperature […]
What is the evidence that light is a wave?
What is the evidence that light is a wave? In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits. The bright and dark bands demonstrated that the slits were causing light waves to interfere with […]

What are three major types of constraints in lean?
What are three major types of constraints in lean? The underlying premise of the theory of constraints is that organizations can be measured and controlled by variations on three measures: throughput, operational expense, and inventory. What are constraints give an example? A constraint, in project management, is any restriction that defines a project’s limitations; the […]

What happens if the body does not maintain homeostasis?
What happens if the body does not maintain homeostasis? When the cells in your body do not work correctly, homeostatic balance is disrupted. Homeostatic imbalance may lead to a state of disease. Disease and cellular malfunction can be caused in two basic ways: by deficiency (cells not getting all they need) or toxicity (cells being […]
