Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel....
Where did the heaviest elements originate? If a molecule is more electronegative, then does it have a higher potential energy? What's the strongest type of metal? What do the members of the noble gas family have in common? a. They are mostly chemically inert. b. They almost never react ...
Three of the engines are designed for sea-level use, and the other three are for use in a vacuum. They use subcooled liquid methane and liquid oxygen propellant. Meanwhile, Super Heavy has a whopping 33 Raptor engines. These are all sea-level variants, giving the stacked rocket a total ...
What I am suggesting is that digital marketing tools can add rocket fuel to your on-the-ground efforts. The fact is that90% of adults in the U.S. are using the internet. And if you’re thinking that this doesn’t have any bearing on the life and work of a small nonprofit organizati...

Methods like radar show that Psyche's surface is highly reflective but don't reveal what the reflective material is, he said. Many scientists think Psyche's surface is made mostly of nickel and iron, since those elements tend to be common in asteroids, he added. ...
What are real-life examples of centripetal and centrifugal force? A simple real-life example of centripetal force is a rock tied to a string. When the string is swirled around, the tension in that string keeps the rock from flying off in a straight line. That tension points inward, toward...
Gases are substances in which the particles are separated from one another by large spaces. They can be obtained from liquids by heating the liquid. Gases take the shape of the container and they can be compressed.Answer and Explanation: ...
Emojis have become an integral part of our messaging experience, be it on WhatsApp, Snapchat, or Instagram. It helps us fill in many emotional and expressive cues, which are otherwise not available through texts. Over the years, many emojis covering life’s aspects have been added. However,...
