The correct procedure is "The type of salt and the amount of water are controls, and the amount of salt and the density are variables".

Explanation:

In the given problem, Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water.

Density measures how much mass in a given volume.

When the salt is dissolved in a water then the density of water increases.

The density is affected by the salinity and the temperature. Salinity describes how much salt is dissolved in water. When the salt is dissolved in the cold water then it becomes denser than the warm water without dissolved salt.

Therefore, the correct statement is "The type of salt and the amount of water are controls, and the amount of salt and the density are variables".

Answer from: Quest

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

Look at the pendulum diagram between which points does the pendulum’s potential energy increase most

Answer from: Quest

cant without the picture! ?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
