Answer:

Copernicus' heliocentric model

Explanation:

Nicolaus Copernicus was the first one to give the heliocentric model of the solar system. The heliocentric model of the solar system describes the sun to be at the center of the solar system and earth and other planets with their moons revolving about it in concentric orbits.

Kepler believed in Copernicus's heliocentric model but gave laws of planetary motion that described the orbit of the planets to be elliptical instead of circular.

Tycho Brahe view of the solar system was that sun revolved around earth but other planets revolved around the sun.

Ptolemy's geocentric model considered earth to be the center of the universe and sun and other planets revolving about it.

I believe it was Copernicus' heliocentric model.

heliocentric - the sun is at the center and the planets revolve around it.

hope this helps :)

A heat pump absorbs heat from the atmosphere at a rate of 30 kW. If work is being done to run this heat pump at a rate of 7.7 kW

Volgvan

Answer:

Option D 3.9

Explanation:

First, you need to use the correct equation which is the following:

COP = Q/W

Where:

Q = heat absorbed

W = work done by the pump

COP = coefficient of perfomance

We have all the data, so, all you need to do is replace in the above expression and you shoould get the correct result:

COP = 30 / 7.7

COP = 3.896

This result you can round it to 3.9. option D.

An alpha particle(the nucleus of a helium atom) has a mass of 6.64*10^-27kg and a charge of +2e. What are the magnitude and dire

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Weight = electric force
mg = qE 

6.64x10^-27 x 9.81 = (2 x 1.60x10^-19) E
qE =mg,
E = mg/q = 6.64•10^-27•9.8/2•1.6•10^-19 =2.03•10^-7 V/m

For a science project, you would like to horizontally suspend an 8.5 by 11 inch sheet of black paper in a vertical beam of light

liubo4ka [24]

Answer:

I = 3.9 x 10⁷ W/m²

Explanation:

given,

Sheet of black paper dimension = 8.5 x 11 inch

Area of sheet = 8.5 x 11 = 93.5 inch^2

1 inch =0.0254 m

Area = 0.06032 m²

mass of sheet = 0.80 g

Force = m g = 0.8 x 9.8 x 10⁻³ N

= 7.84 x 10⁻³ N

speed of light = c = 3 x 10⁸ m/s

Using equation

$F = \dfrac{IA}{c}$

where I is the intensity of light

$7.84 \times 10^{-3} = \dfrac{I\times 0.06032}{3 \times 10^8}$

$2.352 \times 10^{6} = I\times 0.06032$

$I = \dfrac{2.352 \times 10^{6}}{0.06032}$

I = 3.9 x 10⁷ W/m²

Intensity of the light is equal to I = 3.9 x 10⁷ W/m²

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 8 AU, and it takes 71

Mama L [17]

Answer: 11.2 AU

Explanation:

Applying Kepler's 3rd law, we can find out the average distance of planet B to the star.

This Law states that for planets orbiting a same star, there exists a fixed relationship between the average distance to the star, and the period of his orbit around it, as follows:

K = T² / d³

So , in this case, we can write:

(da)³ / Ta² = (db)³ / (Tb)²

Solving for db:

db = ∛8³.(1170)² / 710² = ∛1390.4 = 11.2 AU
