Answer:
Salt issolved in water: homogeneous mixture
muddy water : heterogeneous mixture
Sodium fluoride = compound
Silver = element
Explanation:
Step 1:
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture.
A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition.
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements cannot be broken down using chemical reactions.
Salt dissolved in water = Salt is soluble in water, which would give a homogeneous mixture
Muddy water = Muddy water, on the other hand is a heterogeneous mixture because mud can settle, leaving the mixture with much less mud at the top of the bucket than the bottom.
Sodium floride = a compound made of 2 elements: Sodium and fluoride
Silver = An element, it can be found on the period table.
The resistance will increase cz resistance is inversely proportional to area of cross-section and so if area of cross section is decreased by half the resistance is doubled.
