Creek and cold stand back-to-back and walk in opposite directions for $40$ yards each. each of them then turns left and walks another $30$ yards each. in yards, how far are creek and cold from one another?

[See the attached picture for better Understanding]

After walking 40 yards in opposite directions and then 30 yards to left, Creek and Cold are now standing at the edges of tow triangles and the distance between them is the hypotenuse of two triangles with same measurments. So by using pythagoras theorem we can state that,

Distance between both of them is 100 yards.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.
