How do you calculate the de Broglie wavelength? Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron. Step 3: Think about your result. This very small wavelength is about 1/20th of the diameter of a hydrogen atom. Looking at the equation, as the […]
Can you hear a radio wave?
Can you hear a radio wave? Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched). … Can teeth pick up radio signals? The electrical conductivity of […]
Where are water masses formed?
Where are water masses formed? Water masses are formed as the result of climatic effects in specific regions. Antarctic bottom water is an important water mass that forms on the Antarctic continental shelf as a cold, dense residual brine during the formation of sea ice. Which water mass is the saltiest in the world? That […]
How is charge transfer calculated?
How is charge transfer calculated? Measurements of charge transfer may be made either measuring the voltage developed across a capacitor to earth, instead of the resistor, or using a virtual earth charge measurement amplifier. Another approach is to integrate discharge current flow measurements over the duration of the discharge. Can you transfer battery power from […]
Which layer of the endometrium is the functional layer?
Which layer of the endometrium is the functional layer? The uterus is made up of an external layer of smooth muscle called the myometrium, and an internal layer called the endometrium. The endometrium has three layers: stratum compactum, stratum spongiosum (which make up the stratum functionalis) and stratum basalis. Which of the following is a […]
What year will the sun explode?
What year will the sun explode? In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you. Is Sun getting weaker? […]
What is the frequency of 500 nm wavelength light?
What is the frequency of 500 nm wavelength light? What can be said about the frequency of the wave? Solution: Given, the wavelength of the photon particle = 500 nm. In order to calculate the frequency of the photon particle, we use the formula given above. The frequency of the wave is equal to 6×10-4 […]
What is the degree of freedom at critical point?
What is the degree of freedom at critical point? In the critical point the difference of density between the liquid phase and the vapour phase is so small the are indistinguishable, hence considered as single phase. So according the gibbs phase rule (. F=C – P +2) the degree of freedom should be 2. What […]
What pressure allows you to breathe?
What pressure allows you to breathe? Although it fluctuates during inspiration and expiration, intrapleural pressure remains approximately –4 mm Hg throughout the breathing cycle. Competing forces within the thorax cause the formation of the negative intrapleural pressure. What goes into your body when you inhale what gets out of your body when you exhale? When […]
What absorbs sound the best?
What absorbs sound the best? In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. How do I block traffic noise in my bedroom? Hang heavy curtains or drapes on windows (you could even try hanging heavy […]
