What is the approximate rate of descent required (for planning purposes) to maintain the electronic glide slope at 105 knots ground speed?

555 ft per min

Explanation:

For the problem above, we can use the IAP chart and the ILS RWY 32 L approach. If we consider an electronic glide slope of 3 degrees, with the table of Rate-of-Descent in the IAP chart. Adjusting the angle of descent to 3 degrees and shifting the ground speed to approximately 105 knots, the estimated rate of descent is 555 ft per min.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
