How does the diameter of each ripple change as time passes

VLD [36.1K]

The diameter of the ripple changes by the following equation = $\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

Explanation:

When a pebble or a rock is dropped in the water then the ripples or waves are formed which starts moving radially outward. As the time passes, the radius of the circle increases.

Let D be the diameter of the circle.

$\frac{dD}{dt}$ will be the rate of change of diameter of the circle with respect to time.

Let A be the area of the circle.

$\frac{dA}{dt}$ will be the rate of change of area of the circle with respect to time.

Area of the circle = $\frac{\pi }{4} D^{2}$

So,

$\frac{dA}{dt} = \frac{d [\frac{\pi }{4} D^{2}] }{dt}$

$\frac{dA}{dt} = \frac{\pi }{4} \frac{d[ D(t)^{2}] }{dt}$

Using chain rule,

$\frac{dA}{dt} = \frac{\pi }{4} X \frac{d[D(t)^{2} ]}{d[D(t)]} X \frac{d[D(t)]}{dt}$

$\frac{dA}{dt} = \frac{\pi }{4} . 2D(t) . \frac{dD}{dt}$

$\frac{dA}{dt} = \frac{\pi }{2} X D(t) X \frac{d(D)}{dt}$

$\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

Thus, the following equation determines the change in area in terms of diameter with respect to time : $\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

How does someone achieve a unified self?

lesantik [10]

Answer:

please mark me as brain list

Explanation:

The unified self is a flawed construct. Experience changes us, even at the core. People change us just by being with us. It doesn't have to be a long term relationship. Our minds may not have the plasticity they once had but we adapt daily to the people around us and, in a slower fashion, tide rather than waves rather than ripples, we the ebb and flow of experience changes the "I think" that creates our values and judgements, which changes the experiences we seek then have which again works on the way we view the world.

A possible reason we are able to change when we are with different types of people is that we have a certain number of roles at our disposal. I've noticed this, on an extreme level, with some coworkers. I wondered how they could change so much when they got to the office. They'd suddenly become very business-like and at first I thought they were play acting. They were, in a sense, but I believe their identity changed when they walked through the office door. They were no longer the guy or girl I'd just ridden to work with, they were such and such part of the hierarchy and their behavior wasn't all a put on, though some of everyone's behavior in every role is, it was who they were then.

It took being asked to take a work related personality test that clued me in. The test results came back. One part of results outlined our scores for introversion/extroversion scores at home and at work. The scale was -50 to +50 where the score determined one's level of introversion (-) or extraversion (+). I scored -33 at home and a +33 at work. The automatic scoring algorithm suggested that it was likely I was under a lot of internal stress because of this. I was. I used to have dry heaves when I transitioned from work to home. That part of the results wasn't the only part rang true though so I took it seriously.

How close the roles we play with different people are to each other might be an indicator of how unified we are. If you were to scale our unification factor from 0 to 1 I would have been considered a 0.33 based on my introversion/extraversion scores, if that was the only score that mattered. More things the behavior than others matters, of course. Perhaps people who are very different in differing situations experience more cognitive dissonance. It would be interesting knowing.

Write an argumentative essay which says without photosynthesis there is no life

AysviL [449]

Explanation:

you could include the points such as,

--> photosynthesis produces O2 which is necessary for respiration.

-->photosynthesis reduces the amount of CO2 in the atmosphere as it uses it up in the reaction. this controls the atmospheric rate of CO2 and reduced the greenhouse effect.

--> plants are the primary producers in a food chain and so, photosynthesis plays a primary role in the stability of food chains as they're the primary source of glucose as all the higher consumption is based off the producer.

--> virtually seeing, all the energy within the biosphere is based off plants that depends on photosynthesis.

--> If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.

there could be more but this is all I could think of.

hope it helps. :)

The light colored rock pocket mice in New Mexico blend in with the sandy soil of the area, but on darker lava flow, the light co

Maksim231197 [3]

The answer is; B

Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.

This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
