We can use kinematics here if we assume a constant acceleration (not realistic, but they want a single value answer, so it's implied). We know final velocity, vf, is 1.0 m/s, and we cover a distance, d, of 0.47mm or 0.00047 m (1m = 1000mm for conversion). We also can assume that the flea's initial velocity, vi, is 0 at the beginning of its jump. Using the equation vf^2 = vi^2 + 2ad, we can solve for our acceleration, a. Like so: a = (vf^2 - vi^2)/2d = (1.0^2 - 0^2)/(2*0.00047) = 1,064 m/s^2, not bad for a flea!
<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>
Total distance = 15 kilometers and total displacement = 110 kilometers----- 60 kilometers - 45 kilometers = 15 kilometers 60 + 45 kilometers = 110 kilometers :)))))
True.
The San Andreas fault, though it has not shaken for quite a few years, is, as scientists are saying, getting ready to create one of the largest earthquakes known. A sudden and destructive movement of plates can move the water located above, creating a large wave (tsunamis) that can overflow and flood parts of the Western Coast of the Americas.
hope this helps
