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.

A boy pulls with a 20 N force, at a 20 degree incline. What part of the force moves the wagon?
nalin [4]

Answer:

horizontal direction force move wagon at  18.79 N

Explanation:

given data

force F = 20 N

angle = 20 degree

to find out

What part of the force moves the wagon

solution

we know here as per attach figure

boy pull a wagon at force 20 N at angle 20 degree

so there are 2 component

x in horizontal direction i.e  F cos20

and y in vertical direction i.e F sin20

so we can say

horizontal direction force is move the wagon that is

horizontal direction force = F cos 20

horizontal direction force = 20× cos20

horizontal direction force = 18.79 N

so horizontal direction force move wagon at  18.79 N

How much work (in J) is required to expand the volume of a pump from 0.0 L to 2.7 L against an external pressure of 1.0 atm?
spin [16.1K]

Answer:

-2.79 x 10²J

Explanation:

using the pressure volume work formula which states that

work = -PΔV

           = -(1.0 atm) (2.7-0.0)L = -2.7L . atm

Convert litre.atmosphere to Joules.

1 L . atm = 101.325 joules

-2.75 L .atm = -2.75 x 101.325 = -278.64375 =

Work = -2.79 x 10²J
