What should you not do with a pacemaker? What precautions should I take with my pacemaker or ICD? It is generally safe to go through airport or other security detectors. Avoid magnetic resonance imaging (MRI) machines or other large magnetic fields. Avoid diathermy. Turn off large motors, such as cars or boats, when working on […]

What is a vector vector example? A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. What is called a vector give one example? […]

At what angle a player should throw a javelin to achieve maximum range? 45 degrees At what angle do you launch a ball to achieve longest range? The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 […]

What is Heisenberg Uncertainty Principle explain? Heisenberg’s uncertainty principle is a key principle in quantum mechanics. Very roughly, it states that if we know everything about where a particle is located (the uncertainty of position is small), we know nothing about its momentum (the uncertainty of momentum is large), and vice versa. What is the […]

What is the definition of conceptual? The definition of conceptual is something having to do with the mind, or with mental concepts or philosophical or imaginary ideas. An example of conceptual is when you formulate an abstract philosophy to explain the world which cannot be proven or seen. What is an example of a conceptual […]

Is thermal energy the total kinetic energy of an object? Thermal energy is the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is sometimes confused with internal energy or thermodynamic energy. They consist of the sum of the internal kinetic energy (thermal energy) and the […]

What is the formula of path difference? The general formula for destructive interference due to a path difference is given by δ = (m + 1/2) λ / n where n is the index of refraction of the medium in which the wave is traveling, λ is the wavelength, δ is the path difference and […]

What is the lunar day today? Lunar calendar for today May 7, Friday Today is the Ekadashi day by vedic tradition Moon void of course from 7:36 AM till 11:52 AM 26 lunar day Waning Moon Symbol: Swamp What lunar day means? A lunar day is the period of time for Earth’s Moon to complete […]

What is the density of oxygen in kg m3? 1141 kg/m3 What is the density of gold in kg m3? 19,300 kg/m3 How heavy is 1m3 gold? One cubic meter of gold weighs roughly 19.3 metric tons, or about 42,549.22 English pounds. Is gold high in density? With a density of 19.32 grams per cubic […]

Is a cookie sheet an insulator? It stops the flow of energy from moving through the material. Many objects that are meant for holding hot objects (soup containers, handles of pots and pans) are made out of heat insulators so that the heat will not transfer through the area it touches. For example, Ted is […]
