Newton's laws are still very much used today for a number of applications ranging from planetary motion to the calculation of sprite velocities within computer games. Therefore the correct statement is: Newton's laws can explain the forces that occur between objects every day. Example forces include, gravity and friction.

<h3>What is the Brundtland Commission?</h3>

The Brundtland Commission was set up with the intention to achieve sustainable development. The tenure of the commission lasted from 1984 to 1987.

The commission identified the pillars of sustainable growth as economic growth, environmental protection, and social equality. The committee opined that environmental problem emanates from poverty in the southern region and reckless consumption of resources in the northern region.

A map of eastern North America, showing the pH of rainfall in the various states, indicates that the pH of rain in New York Stat

4.22

Explanation:

The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.

The pH scale expresses the acidity or alkalinity of aqueous solutions.

The pH scale ranges from 1 to 4
An acidic solution will have a pH value less than 7

We have given a range of values between 4.22 to 4.40

This implies that the pH values of rainfall in this region falls between these extremes.

The least value 4.22 is the most acidic

The value 4.4 is the the least acidic

The lower the pH value, the more acidic a solution is.

There are two different size spherical paintballs and the smaller one has a diameter of 5 cm and the larger one is 9 cm in diame

slavikrds [6]

Answer:

145.8 cm³ of paint

Explanation:

d₁ = Smaller diameter paintball = 5 cm

d₂ = Larger diameter paintball = 9 cm

V₂ = Volume of larger diameter paintball

Volume of smaller diameter paintball

$V_1=\frac{4}{3}\pi r_1^3\\\Rightarrow V_1=\frac{4}{3}\pi \left(\frac{d_1}{2}\right)^3\\\Rightarrow V_1=\frac{4}{24}\pi d_1^3$

Similarly

$V_2=\frac{4}{24}\pi d_2^3$

Dividing the above two equations, we get

$\frac{V_1}{V_2}=\frac{d_1^3}{d_2^3}\\\Rightarrow V_2=\frac{V_1}{\frac{d_1^3}{d_2^3}}\\\Rightarrow V_2=\frac{28}{\frac{125}{729}}\\\Rightarrow V_2=163.296\ cm^3$
