Derive Boyle's law.<br>i'll mark the brainliest for the answer​
MArishka [77]

Answer:

According to Boyle's Law, an inverse relationship exists between pressure and volume. ... The relationship for Boyle's Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.

The average atomic weight of copper, which has two naturally occurring isotopes, is 63.5. One of the isotopes has an atomic weig
Darya [45]

<u>Answer:</u> The atomic weight of the second isotope is 64.81 amu.

<u>Explanation:</u>

Average atomic mass of an element is defined as the sum of atomic masses of each isotope each multiplied by their natural fractional abundance

Formula used to calculate average atomic mass follows:

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i     .....(1)

We are given:

Let the mass of isotope 2 be 'x'

Mass of isotope 1 = 62.9 amu

Percentage abundance of isotope 1 = 69.1 %

Fractional abundance of isotope 1 = 0.691

Mass of isotope 2 = 'x'

Percentage abundance of isotope 2 = 30.9%

Fractional abundance of isotope 2 = 0.309

Average atomic mass of copper = 63.5 amu

Putting values in equation 1, we get:

\text{Average atomic mass of copper}=[(62.9\times 0.691)+(x\times 0.309)]

x=64.81amu

Hence, the atomic weight of second isotope will be 64.81 amu.

(A)What type of cloud forms at high altitudes and is wispy and feathery.
posledela
A) Answer D. Clouds forming high in the atmosphere are referred to as cirrus, cirrostratus, and cirrocumulus. 

B) Clouds tend to form at higher altitudes because as<span> air rises, the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.

C) Precipitation: Water that falls to the ground from clouds, such as in rain, snow, sleet, or hail.</span>

A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two grou
alexandr1967 [171]

Answer:

The population of the long-legged birds decreases.

Explanation:

The population of the short-legged birds increases whereas the population of  long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.
