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.
The distance can be measured at regular time intervals, as the trolley moves, and a graph plotted. This type of measurement is best done by a computer where the rapid timings and calculations can be done quickly and results displayed on the monitor.Other techniques are available for detecting distance and speed. number of different techniques can be used for recording the way distance changes over time. One method commonly used in the school laboratory is the ultrasonic motion sensorSensors used in electronics produce a change in their resistance when some feature of their surrounding environment changes.
