What is the time difference in mean solar time between 30° N 75° W and 30° N 90° W?
Answer:
It depends on what kine of unknown substance you're referring to.
Explanation:
What do you mean by unknown substance?
If it's soluble in water and can conduct electricity then it is an ionic compound.. If it is insoluble in water and can't conduct electricity then it is a covalent compound
<span>A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule.</span>
Answer:
Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly. There are two different types of vitamin A. The first type, preformed vitamin A, is found in meat, poultry, fish, and dairy products.
We frequently observe kids playing with polythene bags filled with water that have little holes drilled into them at various locations so they can sprinkle water on other kids. Through this experiment, we can say that pressure acts in all directions in liquids.
<h3>Liquid's pressure</h3>
Since both liquids and gases may flow, they are both referred to as fluids. Fluids under rest pressure behave uniformly in all directions.
Weather forecasts can be made using barometers. They track the evolution of atmospheric pressure throughout time.
On weather forecast maps, pressure variations appear as an isobar pattern. Predictions are made using these changes in pressure, and they are fairly accurate when combined with wind observations.
<h3>Pressure and depth in liquids</h3>
As you go away from a liquid's surface, pressure rises. for instance: A bucket has three holes that are all the same size. Since there is more pressure at the bucket's bottom, the water spills out more forcefully. Dams are thicker at the bottom for this reason.
