Gravity modelPolicy makers are interested in the influence of geographic distance on knowledge flows, however these can be expected to vary across research fields. The effects of geographic distance on flows are analyzed by means of citations to scientific literature. The field of observation ...
How does distance affect gravitational force? How does air resistance affect force of gravity? A centripetal force of 245 N acts on a 1,400-kg satellite moving with a speed of 4,500 m/s in a circular orbit around a planet. What is the radius of its orbit?
When I started this thread last year I was not asking “Why gravity causes bends in spacetime.” I was asking if gravity exists at all without spacetime and mass. My question was sparked by Hawkins and Mladenow’s claim in their Grand Design that gravity (or the laws of gravity) ca...
How do mass and distance affect gravity? What is Newton's second law of inertia? How does momentum affect velocity? How does velocity affect momentum? Calculate the moment of inertia. 1. 2. 3. Inertia keeps your vehicle moving until what happens?
Does the Coriolis force increase or decrease with wind speed? A ball is at rest 103.70 meters above the ground. If it is allowed to fall under the influence of gravity only (ignore air resistance), how fast (in meters per second) is it moving just before hitting the ground? What force...
Faraday, for instance, devised experiments in 1850 to find a possible relation between gravity and electricity. After many experiments he could not find any effect. His closing remarks (1), however, encourage many researchers working in this direction: "Here end my trials for the present. The ...
When λj < 0, refinery j deviates from its ideal crude slate to one with an average API gravity that is lighter (Qj− > 0), and when λj > 0, it deviates to one with an average API that is heavier (Qj+ > 0). We define a new variable DCij to measure the marginal cost of...
50) Many posture gurus will talk about something like “an efficient response to gravity” with confidence, which is really just a fancy way of saying “straight and aligned.” I do not believe that anyone actually knows what an “efficient” posture is, and it is not necessarily defined ...
What is mean by the specific gravity? what are inertial and non-inertial frames, explain them with proper examples? In relation to physics, explain the terms apparent and absolute magnitudes. Why is sometimes component of some forces added in the same direction and some are equated t...
If the distance between the Earth and the Sun is suddenly tripled, how does the gravitational attraction between the two bodies change?Answer and Explanation: If the distance between the Earth and the Sun were to be trippled, the gravi...
