What are the 7 principles of training? The principles of specificity, progression, overload, adaptation, and reversibility are why practicing frequently and consistently are so important if you want to improve your performance. Missed sessions cannot really be made up within the context of a single season. What are the 6 Fitt principles? The exercise frequency, […]
How do we detect planets?
How do we detect planets? The following methods have at least once proved successful for discovering a new planet or detecting an already discovered planet: Radial velocity. Transit photometry. Reflection and emission modulations. Relativistic beaming. Ellipsoidal variations. Pulsar timing. Variable star timing. Transit timing. Which exoplanet discovery method was the most successful early on? The […]
What type of image does a compound microscope produce?
What type of image does a compound microscope produce? With the compound microscope, this intermediate image is real, formed by the objective lens. In all cases, the function of the eyepiece is to form a virtual, magnified image for your eye to view. The microscope is a combination of an objective lens and a magnifier, […]
Why is temperature low at high altitude?
Why is temperature low at high altitude? The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations. The heating of the earth itself also […]
Why does the second and third order spectra overlap?
Why does the second and third order spectra overlap? Show that the second- and third-order spectra of white light produced by a diffraction grating always overlap. What wavelengths overlap? Because the value of the sine increases with angle, this means , so the order overlap. What is the angle of second order diffraction? ±2 How […]
Do stones explode in fire?
How do you express temperature range?
How do you express temperature range? Definitely nothing wrong with the way the temperature range is expressed. When using the degree symbol in expressing a range of temperatures in Celsius or Fahrenheit, both numbers in the range can have the symbol, thus: Water is as a liquid within the 32º – 212º F range • […]
What are four factors that affect the rate of a chemical reaction?
What are four factors that affect the rate of a chemical reaction? There are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. Physical state of the reactants and surface area. Temperature. Presence of […]
