What is the purpose of a spectrograph? A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate. Many astronomical observations use telescopes as, essentially, spectrographs. What are spectral features of an image? Spectral features of images, […]
What is flux in electric field?
What is flux in electric field? Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. […]
Can Methanol hydrogen bond with itself?
Can Methanol hydrogen bond with itself? Methanol is certainly similar to formaldehyde in some ways. It is these strong hydrogen bonds that are responsible for the relatively high boiling point of methanol; there is so much positive charge on the hydrogen of the OH group that it can essentially form a real bond with the […]
Can you feel when your brain is touched?
Can you feel when your brain is touched? How much you empathize with other people seems to reflect how strongly your brain—your primary somatosensory cortex—“feels with” them when you see them being touched. Of course, all these claims require further investigation. And, of course, empathy is a complex phenomenon. Does the brain touch the skull? […]
What are natural resources quizlet?
What are natural resources quizlet? A natural resource is anything that people can use which comes from nature. Examples of natural resources are air, water, wood, oil, wind energy, hydro-electric energy, iron, and coal. What is an example of a renewable natural resource? Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind […]
How does electrostatic occur?
How does electrostatic occur? Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. The rubbing of certain materials against one another can transfer negative charges, or electrons. […]
Do bulbs in series have the same brightness?
Do bulbs in series have the same brightness? Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in […]
What is the moral of the story Frankenstein?
What is the moral of the story Frankenstein? One message conveyed by Frankenstein is the danger that lies with considering the negative consequences of science and technology after-the-fact, instead of before. What is the overall message of Frankenstein? Shelley’s most pressing and obvious message is that science and technology can go to far. The ending […]
Can depreciation be deferred?
Can depreciation be deferred? Depreciation is the loss in value an asset sustains over its useful life. However, depreciation can not be deferred. Why is depreciation a deferred tax liability? The depreciation of fixed assets is a common example that leads to a deferred tax liability. Usually, a company will report depreciation in their financial […]
How does the shockwave of an explosion kill?
How does the shockwave of an explosion kill? Blast Effects Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. For the most part, a nuclear blast kills people by indirect means rather […]
