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 most common damage from car accidents?
What is the most common damage from car accidents? A soft tissue injury is damage to the body’s connective tissue, which means muscles, ligaments and tendons. This is the most common type of injury resulting from a car accident. Soft tissue injuries can take many forms. A “whiplash” type injury to the neck and upper […]
Does higher pressure mean more flow?
Does higher pressure mean more flow? Flow rate is the effect. Higher pressure causes increased flow rate. If the flow rate increases, it is caused by increased pressure. What is the relation between speed and flow rate? Flow rate and velocity are related by \(Q=A\overline{v}\\\) where A is the cross-sectional area of the flow and\(\overline{v}\\\) […]
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 […]
Which two factors are needed to calculate the velocity of an object?
Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Speed, the […]

How do you increase surface area?
How do you increase surface area? The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. How can you increase the surface area of water? Surface tension is the energy […]

What 3 categories do biological rhythms fall into?
What 3 categories do biological rhythms fall into? There are three types of biological rhythms: Circadian rhythms: biological cycles that occur about every twenty-four hours. Sleep follows a circadian rhythm. Infradian rhythms: biological cycles that take longer than twenty-four hours. Ultradian rhythms: biological cycles that occur more than once a day. What is an example […]
What are the 3 main map projections?
What are the 3 main map projections? This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection. What are the 5 map projections? Top 10 World Map Projections Mercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. Robinson. This map is known […]
