Learn about specific gravity, its relation to density, and how to convert one unit to the other. See which instruments are used to measure specific gravity.
Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories ...
Gravity can be described in a variety of ways. Here's how Newton and Einstein took gravity from an observation to a measurable phenomenon.
(Kepler's second law of planetary motion tells us that the closer an object is to the sun, the faster it will orbit.) However, Earth's gravity can pull back on a spacecraft, slowing it down. At L1, all of these forces are in balance, and a spacecraft at L1 would be moving slow...
In the same manner, an astronaut is in free fall under the Earth's gravity but is also moving so fast forward that during the time he's fallen a foot, he's moved far enough forward that the curvature of the Earth has dropped a foot below him. For every foot he moves toward the ea...
What is specific gravity? Specific gravity, more formally known as relative density, is a measure of thedensityof a substance in comparison to the density of water. Forsolidsandliquids, specific gravity is generally measured in relation to water at its densest state (at temperatures of 4 Celsius...
Maybe someone from HR mentioned that term, or you saw that in a job ad? These skills are all the rage now. But what are they, exactly? Who needs them, and why is that so? Learn the importance of strong interpersonal skills now. This article will show you: What interpersonal skills ...
exists in all areas of our lives,including the workplace.Bias can also negatively affect hiring decisions. If you want to hone your critical thinking skills, you must learn to avoid it. Again, it can be difficult at first. However, becoming more aware of it is the first step to success...
In the present perfect tense, the main verbs always use the auxiliary verbs (helper verbs) has or have. The main verb takes a participle form, specifically the past participle. The past participle is often the same form as the simple past form of the verb unless it’s an irregular verb ...
What Is a Patent? A patent is the granting of a property right by a sovereign authority to an inventor. This grant provides the inventor exclusive rights to the patented process, design, or invention for a designated period in exchange for a comprehensive disclosure of the invention. They are...
