What is the measurement of the velocity of moving particles the Doppler effect is based on?

Biology

Keith_Richards [23]3 years ago
7 0
The Doppler effect is the phenomenon whereby a monochromatic wave reflected by a moving target undergoes a frequency shift which is proportional to the target velocity, namely ω = ωo(1 − v · n/c), where v is the target velocity, c is the wave velocity and n is the unit vector in the direction of the reflected ray.

Which term describes the difference in the concentrations of a substance across a cell's membrane?
SpyIntel [72]

Correct answer: C) Concentration gradient

The process of movement of a particle in a solution from the region of higher concentration to the region of lower concentration across a membrane is called as concentration gradient.

For example: If we drop a few drop of dye in a glass of water, it will diffuse along a concentration gradient, i.e, the region where dye is found in highest concentration to the region where it is in lower concentration.

It will occur until the concentration of dye become uniform in all the direction in the glass of water.

iris [78.8K]

Answer:

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.

Explanation:

This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.

<h3>What is Mike Velings talks about?</h3>

Industrial aquaculture has had a wide range of negative effects on the environment, including the overfishing of wild fish to feed carnivorous farmed fish and the escape of farmed fish from their containment, which endangers local wild fish populations.

Lastly, in the words of Mike Velings, We are approaching a worldwide food crisis, he said. At our current rate, we are already taking more fish from the ocean than it can naturally replace, despite the fact that almost 3 billion people rely on the ocean for their food. Mike Velings, an entrepreneur and conservationist, offers a solution in this fact-filled, eye-opening talk: the practice of farming fish. "We need to stop hunting the ocean and start farming it,"
