Why do we use Laplace Transform? The Laplace transform has a number of properties that make it useful for analyzing linear dynamical systems. The transform turns integral equations and differential equations to polynomial equations, which are much easier to solve. Once solved, use of the inverse Laplace transform reverts to the original domain. What is […]
What best describes a difference between the second sound wave in the first?
What best describes a difference between the second sound wave in the first? What best describes the difference between the second sound wave and the first? The air molecules in the compressions of the second wave are more dense. The air molecules in the second wave are closer together on average, so they travel faster. […]
Does higher temp mean more heat?
Does higher temp mean more heat? Hotter objects have a higher average kinetic energy and a higher temperature; cooler objects have a lower average kinetic energy and a lower temperature. But it is their average speed that determines the amount of heat an object has and what its temperature is. Why does heat capacity change […]
What is a device that converts mechanical energy to DC electrical energy?
What is a device that converts mechanical energy to DC electrical energy? In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit. DC generator or direct current generator generates a voltage when speed and flux are met. This machine is called a unidirectional (dynamo). […]
Which even happens in a solar cell when the photoelectric effect occurs?
Which even happens in a solar cell when the photoelectric effect occurs? Answer. Answer: Light shone on metal expulses electrons from its surface. This phenomenon is the photoelectric effect, and the electrons are called photoelectrons. How can we apply photoelectric effect in daily life uses? The rest of the photon’s energy transfers to the free […]
What is an example of an experimental design?
What is an example of an experimental design? This type of experimental design is sometimes called independent measures design because each participant is assigned to only one treatment group. For example, you might be testing a new depression medication: one group receives the actual medication and the other receives a placebo. Group 1 (Medication 1). […]
What is the difference between a wheel bearing and axle bearing?
What is the difference between a wheel bearing and axle bearing? The differences between front wheel bearings and axle bearings are significant. Wheel bearings are installed in pairs consisting of both inner and outer bearings, whereas axle bearings are installed as a single bearing and only support the outer end of the axle shaft. Are […]
How do the geosphere and hydrosphere work together?
How do the geosphere and hydrosphere work together? When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth’s surface. That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. […]
Does hot rolling increase hardness?
Does hot rolling increase hardness? It had be concluded so far that in hot rolling, increase in height of roll grooves which was a function of its expansion, caused by the process parameters, resulted in increase in thickness of rolled stock, which affected the mechanical properties of the rolled samples such as ultimate tensile strength, […]
What are the 7 types of fractions?
What are the 7 types of fractions? The six kinds of fractions are, proper fractions, improper fractions, mixed fractions, like fractions, unlike fractions and equivalent fractions. What is a mixed number? What is a mixed number? A mixed number is a number consisting of a whole number and a proper fraction. What does a mixed […]
