But donât take over-the-counter (OTC) cough suppressants unless coughing keeps you up at night, Dr. Hanania advises. That's because, true to name, they suppress the cough â keeping the mucous in. If you take anything, âa mucolytic [which breaks down or thins mucous in the respiratory tract] may soothe the coughâ and make it more moist, he says.
Answer: It is not an easy thing to measure the distances to objects in the universe since these objects are usually very far away. We can't just run out there with a ruler! To measure distances in the universe, we will need to construct what is commonly referred to as a cosmic distance ladder.he links below will take you to descriptions of various common methods. 1  Radar-measuring distances in our solar system. 2  Parallax-measuring distances to nearby stars. 3  Cepheids-measuring distances in our Galaxy and to nearby galaxies.
Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.
