wire, metal or other material that swings back and forth. Pendulums are used in everything from grandfather clocks to metronomes. Scientific principles govern what affects the swing rate of the pendulum, and th
How can they affect operational processes? What is it called when the effect can only be explained by the cause and cannot be explained by a third variable? What is the value of Bending Moment acting just to the left, point B, of the 6 kN force on the beam show...
Moreover, Maliverno added, computer modeling studies that tried to reproduce the current climate change using only natural variables, such as the Milankovitch cycles, couldn't match the rate of warming we see today. When will be the next ice age? Still, even without the current man-made cli...
How does gravity affect Eris, the dwarf planet? What does Kepler's third law imply about planetary motion? Who invented the perturbation theory for planets? How big is a gravitational singularity? What is accretion of planetesimals? What do the variables in the nebular hypothesis mean?
Does a Gravitational Field Continuously Regenerate, or is it “Frozen?” In attempts to describe how GR can affect distant bodies seemingly without delay, relativists often speak of the field of a body as if it were a rigid extension of the body itself If such a “static” field has no ...
Two of the main things that affect decomposing are basically the same ones you pay attention to when you check the weather report — temperature and humidity. The hotter it gets, the quicker the decomposing processes become. Meanwhile, water and cold can slow them down. Oxygen is also a fact...
whereHis the Hubble parameter andGNewton’s gravitational constant. A universe with a matter density above this value will be spatially closed, while a lower-density universe will be spatially open. In a two-dimensional toy universe, a sphere is an example of a closed geometry, while a saddle...
Many people think that space and time are completely different variables, but physicists often combine them into “space-time”. Space-time is a four-dimensional coordinate system used in relativity and other areas of physics. The dimensions are, length, width, height, and the 4th is the time...
Consider for a common example the Universal Law of Gravitation (ULG), which states that the force of gravitation between any two objects is equal to the product of their masses over the square of the distance between them times the gravitational constant. We can use this law in conjunction ...
When a conservative force does positive work on a body, how does it affect the potential energy of the body? Define depolarization, repolarization, and the action potential. Define what is Electromagnetic Energy. What does it mean for two variables, such as current and potential, to have a li...
