HACTEHA [7]2 years ago

Explanation:

<h3>Using clean, renewable energy is </h3><h3>one of the most important actions </h3><h3>you can take to reduce your impact </h3><h3>on the environment. Electricity production is our #1 source of greenhouse gases, more than all of our </h3><h3>driving and flying combined, and clean </h3><h3>energy also reduces harmful smog, toxic buildups in our air and water, and the </h3><h3>impacts caused by coal mining and gas extraction. But replacing our fossil-fuel infrastructure will take</h3><h3> time—and strong, consistent support from both state and federal </h3><h3>mandates to build renewable energy generation and demand for clean energy from consumers and businesses.</h3>

<h3>Why Renewable Energy? </h3>

<h3>Electricity generation is the second leading cause of industrial air</h3><h3> pollution in the U.S. </h3><h3>Most of our electricity comes from coal, nuclear, and other non-renewable power plants. Producing energy from these </h3><h3>resources takes a severe toll on our environment, polluting our air, land, and</h3><h3> water.</h3>

<h3>Renewable energy sources can be used to produce electricity with</h3><h3> fewer environmental impacts. It is possible to make electricity from renewable energy sources without producing carbon dioxide (CO2), the leading cause of global climate change.</h3>

<h3>Renewables Benefit the Economy</h3><h3>Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security, </h3><h3>lower risk of fuel spills, and reduce</h3><h3> the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.</h3>

A small omnidirectional stereo speaker produces waves in all directions that have an intensity of 8.00 at a distance of 4.00 fro
slavikrds [6]

Answer:

A. We have that radius r = 4.00m intensity I = 8.00 W/m^

total power = power/ Area ( 4πr2)= 8.00 w/m^2( 4π ( 4.00 m)2=1607.68 W

b) I = total power/ 4πr2= 8.00 W/m2 ( 4.00 m/ 9.5 m)2= 1.418 W/m2

c) E = total power x time= 1607 . 68 W x 1s= 1607.68 J

Explain why materials such as plastic foam, feathers, and fur are poor conductors of heat.
Firlakuza [10]
The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this. 

<span>Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat). hope that helped.</span>

a basketball player can leap upward .65m how long does the basketball player remain in the air use 9.81m/s²​
tigry1 [53]

At the player's maximum height, their velocity is 0. Recall that

{v_f}^2-{v_i}^2=2a\Delta y

which tells us the player's initial velocity v_i is

0^2-{v_i}^2=-2g(0.65\,\mathrm m)\implies v_i=3.6\dfrac{\rm m}{\rm s}

The player's height at time t is given by

y=v_it-\dfrac g2t^2

so we find their airtime to be

0.65\,\mathrm m=\left(3.6\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2\implies t=0.36\,\mathrm s
