Which of the following is not a characteristic of the source of rivers and streams?

1 answer:

7 0

The water is clearer, has higher oxygen levels, and freshwater fish such as trout and heterotrophs can be found. In the middle of the river, the width increases, so do the species of aquatic green plants and algae. Toward the mouth of the river, the water becomes murky from all the sediments that it has picked up upstream.

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phen

Naddika [18.5K]

An analogy to explain this phenomena is the traffic explanation: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one lane instead of being spread out on all six lanes. With more paths, there is less resistance to flow.

Your answer is: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one land instead of being spread out on all six lanes. With more paths, there is less resistance to flow.

Have an amazing day mate!

Amanda goes shopping for light bulbs. In the light bulb aisle, she finds the following incandescent light bulbs. Can you help he

Luden [163]

Answer:

The least efficient light bulb is the first one (25 W - 210 Lumen)

Explanation:

Efficiency can be defined as what you want to obtain over what you need to produce it. In this case Eff= Wattage / Lumen. For each light bulb, their efficiency is: 8.4 / 11.12 / 15.7 Lum/W

A dvd drive has a maximum speed of 72000 revolutions per minute. if a dvd has a diamter of 12 what is the linear speed

Brilliant_brown [7]

The question isn't clear enough, I think it ask us to calculate the linear speed of a point at the edge of the DVD.
Now let's imagine we're a point at the edge of the DVD, we're undergoing a circular motion. Each minute we will complete a circular track 7200 times, now we need to know the distance we travel each turn. The perimeter of the DVD, a circular object is:
$P=2\pi.R$
Know recall that:
$v=\frac{d}{t}$
We now need to know how much distance is traveled during a minute or 60 seconds:
$D=7200\times 2\pi\times R$
Finally we divide this result with t=60 seconds:
$v=\frac{7200\times2\pi\times R}{60}
\\
R=\frac{12}{2}=6
$
$v\approx 4523.89 \frac{units}{second}$
Where the distance units were named units as the length unit is not specified in this exercise.

In what direction does the induced current flow in the loop?

bogdanovich [222]

Answer:

Clockwise and counter clockwises, depands.

Explanation:

The direction of current in a loop of wire in a magnatic field depands on the direction in which the loop is moved and the applied magnatic field.

this is determined by what is called right hand rule.

I will give one scenario, let's say that the loop is moved upwards and the applied magnatic field is into the page (if you drew the loop in 2D on a piece of paper), in this case the direction would be clockwise.

How is a front defined in terms of weather ?. A) the leading edge of an anticyclone flow. B) the trailing edge of a warm front.

Svetllana [295]

A front is defined as a "boundary" that separates two masses of different air densities. I am not entirely sure, but I think the answers are either C or D, but I'm mostly convinced it's option D.
