Answer:
A. paths of the planets follow an elliptical orbit around the sun.
Explanation:
Nicolás Copernicus formulated the heliocentric theory of the solar system, where the Sun is the one in the center with the planets moving around it, contradicting what was believed for the time that it was that the Earth was in the center and both the Sun and the planets revolved around him (geocentrism).
This was the basis for Kepler finally describing the planetary movement based on 3 mathematical expressions. These expressions start by saying that the orbits were not circular, if not elliptical, so that the planets are governed by the Pythagorean laws of harmony. His studies showed that the distances of the planets to the Sun drew parallel spheres, being the first to draw the concentric orbits of the planets in their orbits around the Sun.
Kepler's laws are the following:
- First law. The planets move in elliptical orbits, the sun being one of the foci.
- Second law. The radius vector that joins the center of the Sun with the center of a planet describes equal areas in equal times.
- Third law. The squares of the periods of the planets are proportional to the cubes of their distance from the Sun.
Answer:
0.02896 kg/s
Explanation:
= Initial displacement = 0.5 m
= Final displacement = 0.1 m
t = Time taken = 0.5 s
m = Mass of object = 45 g
Displacement is given by
At maximum displacement
The magnitude of the damping coefficient is 0.02896 kg/s
Answer:
Explanation:
we know that electric field is given as
from the figure electric field c and electric field a CANCEL OUT EACH OTHER
so, we have E_B and E_D is toward -q direction
