The correct answer is A. Heliocentric theory

Explanation:

Galileo Galilei was an Italian astronomer, mainly known for his observations that led Galilei to conclude planets revolve around the Sun (Heliocentric theory) instead of the sun and other planets revolving around the Earth (Geogcentrict theory). One of the observations that make Galilei drew this conclusion were telescopic observation of Venus, in this Galieli noticed similar to the moon Venus had different "phases" or changed its size and lighting, which was only possible if the sun was in the center of the solar system and planets revolve around it including the Earth. Thus, that Galileo was Venus changing size proved the Heliocentric theory.

A circle has a diameter

torisob [31]

The circumference of circle is 20.096 units

Solution:

Given that circle has a diameter with endpoints at (10, 8) and (5, 4)

To get the diameter, find the distance between the end points

The distance between two points is given by formula;

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Here the points are (10, 8) and (5, 4)

$(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)$

Substituting the values we get,

$\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}$

$d = \sqrt{41} = 6.4$

Thus the diameter is 6.4 units

The circumference of the circle is given by formula:

$c = \pi d$

Where "d" is the diameter of circle

$c = 3.14 \times 6.4 = 20.096$

Thus circumference of circle is 20.096 units

Explain what power companies in your area are doing to reduce dependence on nonrenewable energy sources.

madreJ [45]

Answer

• Driving a more fuel-efficient car to eliminate “gas guzzling”

• Reducing heating needs

• Reducing lighting needs

Explanation

The three best strategies employed worldwide for conserving non-renewable energy resources are Reduce, Reuse and Recycle( 3R’s). Energy users are encouraged to increase reliance on renewable energies such as solar, wind and geothermal to aid in conserving the scarce fossil fuel that remain.

Walking and biking can be used as a strategy to cut down gas guzzling and manage the limited nonrenewable oil resources. One popular way of heating homes is oil heating. However, the conserve the oil, home owners are supposed to put up storm windows and insulate homes including caulking cracks around doors and windows to reduce heating costs. When using natural gas, users can reduce energy wasting by keeping the thermostat at 70 degrees and shutting off heat when not in use.

Answer:

a mountain is made by movement and volcanoes are formed by wind. (more info below)

Explanation:

fold and fault mountains are formed by various geological processes, such as the movement and opposition of tectonic plates, but a volcano is formed around a wind that allows magma to reach the surface of the earth. It's just about plate tectonics.
