What shapes the universe? The gravitational effect of matter can affect the curvature of space, per general relativity, but quantum effects during the Big Bang also influenced the shape of the universe. Is the universe a sphere or flat? Whether the universe is flat or curved like a sphere ...
What parameter controls the location of the Normal curve? Which is wider, 95% or 99% confidence intervals? Why? Which data set has the largest median? What is the median score? (a) What does the intercept indicate? (b) What does the slope indicate?
What statistic identifies the gravitational center of a distribution? What term is used to determine how far away the data values are from the mean? What does it mean to collapse across a factor? (a) What is the range? (b) Why is it not the most accurate measure of variability? (c)...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
While the first gravitational wave observation by LIGO in 2015 was of a black hole collision, it did not come with an electromagnetic counterpart that allowed for a redshift calculation that would yield a Hubble’s law measurement. However, a later collision of neutron stars, observed in 2017,...
(physics) The gravitational potential: the radial (irrotational, static) component of a gravitational field, also known as the Newtonian potential or the gravitoelectric field. Possibility That which is possible; a contingency; a thing or event that may not happen; a contingent interest, as in ...
where\(\eta\)is the surface elevation,\(M\)and\(N\)are the discharge in the\(x\)and\(y\)directions,\(t\)is the time,\(h\)is the water depth,\(D\)is the flow depth (\(=\eta +h\)),\(g\)is the gravitational acceleration,\(\alpha\)is the ratio of the densities of the...
