The answer is D. Tension force :))
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>
It all depends on the SIZE of the balloon.
If the balloon is made of really tough rubber, and it holds the helium in the same volume as the solid iron block, then the buoyant force of the atmosphere is the same for both objects.
But if the balloon is just some flimsy stuff, and it lets the helium expand to a much bigger volume than the iron block, then the buoyant force on the balloon is greater than the buoyant force on the solid iron block.
In fact, it DOESN'T MATTER what's in the balloon and what's in the block. It doesn't matter whether either one of them is solid, liquid, or gas, and it doesn't matter whether they have the same or different mass.
Whichever one has greater VOLUME has a greater buoyant force of atmosphere acting on it.
Yes, they both are, and you'd just be working with complex numbers instead of real number.
Answer:
A helpful mutation like camoflage would immensely help a species survive and flourish. The reason being the appliances of such a mutation. Camoflage is one of the most apllicable of abilities. It can be used as a defense mechanism, to hide in plain sight, it can be used offensively to avoid being seen while hunting and it can even be used as a form of communication between the species. All of these appliances would greatly benefit the species and would most definitely help it survive and flourish.
