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.
Parallax and Distance to Stars. 9.1 Purpose. In this lab, we will answer the question of how we determine the distance to nearby stars. Obviously, itâs not as simple as getting out a meter stick or monitoring the odometer on your. space shuttle. Astronomers have to ï¬nd clever ways to determine the distance to stars. 9.2 Introduction. The distance to stars relatively near to the Earth can be measured using a method call. parallax. As a simple demonstration of parallax, hold your ï¬nger about a foot (30 cm) in. front of your face. Close or cover one eye and notice what is behind your ï¬nger.
