A source from which organisms generally take elements is called C. Exchange Pool.

Answer: C. Exchange pool.

Explanation:

The exchange pool can be define as the pool which includes the elements which are required to be exchanged between the abiotic and biotic components of the environment. This is the part of every biochemical cycle.

On the basis of the above explanation, an exchange pool is the source from which the organisms generally take elements so as to lead their life cycle. For example, the atmosphere is the exchange pool of gaseous elements such as water vapors, oxygen, carbon dioxide and nitrogen. The organisms take oxygen from the atmosphere for respiration and release out carbon dioxide which becomes the part of the atmosphere.

vlada-n [284]

Answer:

50 m

Explanation:

F = ma

10 N = (10 kg) a

a = 1 m/s²

Given:

v₀ = 0 m/s

a = 1 m/s²

t = 10 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (0 m/s) (10 s) + ½ (1 m/s²) (10 s)²

Δx = 50 m

A sinusoidal wave travels along a string. The time for a particular point to move from maximum displacement to zero is 0.13 s. W
vitfil [10]

Answer:

Part a)

T = 0.52 s

Part b)

f = 1.92 Hz

Part c)

speed = 3.65 m/s

Explanation:

As we know that the particle move from its maximum displacement to its mean position in t = 0.13 s

so total time period of the particle is given as

T = 4\times 0.13 = 0.52 s

now we have

Part a)

T = time to complete one oscillation

so here it will move to and fro for one complete oscillation

so T = 0.52 s

Part b)

As we know that frequency and time period related to each other as

f = \frac{1}{T}

f = \frac{1}{0.52}

f = 1.92 Hz

Part c)

As we know that

wavelength = 1.9 m

frequency = 1.92 Hz

so wave speed is given as

speed = wavelength \times frequency

speed = 1.92 \times 1.9

speed = 3.65 m/s

Which quantity is most closely related to the speed of gas particles
natali 33 [55]
Temperature is a measure of the energy of molecules and energy is related to speed. 

<span>The water in a pot is heated by convection. The water on the bottom will warm up and rise toward the surface and the cooler water will then sink to the bottom where it will be heated. </span>

<span>Oxygen will form ionic bonds with nitrogen. The others will not by themselves. </span>

<span>A high pH is indicative of a basic solution. HCl and H2SO4 are both strong acids and will result in a lower (more acidic) pH. Water is the standard. KOH is a strong base and will increase the pH. </span>

<span>An acidic solid will lower the pH of a solution. pH measures the number of hydrogen ions and a lower pH will mean that there are more H+ ions, but the solid could just have reacted with the OH- to cause the pH to decrease</span>
