<h2>Hello!</h2>
A sustainable practice is B. Setting usage limits on a resource
<h2>Why? </h2>
Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.
Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).
Have a nice day!
The mass of a lead ball with a radius of 0.50mm is 5.9714226× g
The density of a substance is defined as the mass of substance per unit of its volume. Density is represented by the symbol, ρ.
The formula for density is -
Density (ρ) = <u> mass (m) </u>
volume (v)
Given :
Density of lead = 11.4 g/cm³
Radius of lead ball = 0.50 mm = 0.05 cm
Since,
Vsphere = 4/3 π r³
v = <u>4 </u>× 3.14 × (0.05)³
3
v = 4.18 x (1.25 x 10⁻³)
v = 5.225 x 10⁻³
Since,
Density = <u> mass </u>
volume
11.4 g/cm³ = <u> mass </u>
5.225 x 10⁻³
mass = 11.4 x (5.225 x 10⁻³)
mass = 5.9565 x 10⁻² or 0.05955 g
So, the mass of a lead ball with a radius of 0.50mm is 5.9565 x 10⁻² g
