At first, the idea of repulsive gravity between matter and antimatter seems to go against intuition, since we usually consider mass to be the only component determining an object’s gravitational behavior. But as Villata explains, there is more than just mass involved in gravity. In this case,...
Explain the skeletal muscle pump. Circulation: The term circulation refers to the blood moving to and from the heart in the human body. While blood moves easily away from the heart due to high pressure and gravity, it becomes more challenging to return blood to the heart due to lower pressu...
As physicists say, you have to "do work" to climb a ladder (work against the force of gravity) and use energy. The energy you use isn't lost, but stored by your body as gravitational potential energy, which you could use to do other things (whizzing down a slide back to ground ...
Can modified gravity explain accelerated cosmic expansion? Phys - Dolgov, Kawasaki () Citation Context ...difications of gravity itself with different terms of higher order gravity have recently come into consideration [31, 34, 35]. However, the 1 term modification has been shown to lead to ...
More variation: "more water than *we* fed into it" ie not counting water from the river that feeds it, or rainfall. There's also the title text turn of phrase "heavy water reactor". "heavy" could refer to either the "water" (in the sense of gravity, or deuterium passing through),...
The Parker Solar Probe is using seven Venus flybys to reach its first close approach. The maneuvers will last nearly seven years, before the real mission starts.Project Lyra is a proposed mission to Oumuamua using gravity assists from Earth and Jupiter to perform a sun flyby at 3-10 ...
Among various definitions of the term "stress", a common denominator is that stress denotes any condition being a threat to homeostasis in a broad sense [20,21]. Stress occurs whenever there is a discrepancy between what is expected ("set value") and what really exists ("actual value"); ...
Trying to chase down a chord to switch to, as one would clearly assume would happen, proved almost comically fruitless—every time I tried, it felt like I was trying, and I’d laugh it off and just keep going in that same B-flat; anything else felt like it undermined the gravity or...
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwelling determines large-scale oceanic circulation properties like heat and
