Answer:
10.9%.
Explanation:
The first thing to do in order to solve this question is to Determine the value for the volume of the the cube. This can be done by taking the cube root of the length of the cube;
The volume of the cube = (length of the cube)^3 = length × length × length = 1.72 × 1.72 × 1.72 =( 1.72)^3 = 5.09cm^3.
The next thing you do is to Determine the exponential density, the can be done by using the formula below;
The exponential density = mass/ volume = 55. 786/ 5.09 = 10.96 g/cm^3.
Therefore, the percent error = (true density of the cube - exponential density of the cube)÷ true density of the cube × 100.
Hence, the percent error = 12.30 - 10.96/12.30 × 100 = 10.9%.
I believe it forms an anion that has a larger radius.
Answer:
wave velocity= frequency × wave length
=1×3
=3m/s
Explanation:
The distance covered by the wave in one second is equal to its wavelength, therefore,
wave velocity=wavelength/time period
OR wave velocity= frequency× wavelength
You can assume velocity as speed here.
