2.63% error

Take the formula for percent error

Accepted value minus experimental value over accepted value then multiplied by 100.

The experimental value is 4.29
The accepted value is 4.18

4.18-4.29/4.18 x 100

Use absolute value if negative

Sound travels faster through solids than it does through either liquids or gases a student could verify this statement by
irina [24]

Group of answer choices.

A. Distance that sound travels through a solid, a liquid, and a gas.

B. Pitch of sound when it passes through a solid, a liquid, and a gas.

C. Distance sound travels through a solid, a liquid, and a gas at varying temperatures.

D. Time required for sound to travel a set distance through a solid, a liquid, and a gas.  

Answer:

D. Time required for sound to travel a set distance through a solid, a liquid, and a gas.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the time required for sound to travel is given by this formula;

Time = \frac {distance (x)}{speed (v)}

Hence, the time taken for sound to travel through each medium (solid, liquid and gas) would be measured, recorded and compared to one another.

Write the information obtained from solubility curves.​
salantis [7]

Explanation:

The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.
