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>
Net force is centripetal force that's inward directions
<span>Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well. The animation at the right depicts this by means of a vector arrow. </span>
<span>An object moving in a circle is accelerating. Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. </span>
<span>The final motion characteristic for an object undergoing uniform circular motion is the net force. The net force acting upon such an object is directed towards the center of the circle. The net force is said to be an inward or centripetal force. Without such an inward force, an object would continue in a straight line, never deviating from its direction. Yet, with the inward net force directed perpendicular to the velocity vector, the object is always changing its direction and undergoing an inward acceleration. </span>
<span>The direction is inward therefore the net force is zero. </span>
Answer:Ultraviolet radiation has shorter wavelengths and higher energy than infrared radiation.
Explanation: Electromagnetic radiation radiations which have both electrical and magnetic properties,they can be transmitted through space or through a medium.
It includes Gamma radiation, infra-red, visible light, Ultraviolet radiation etc they occur with different wavelength, the lower the wavelength the higher the Energy dissipated per photon. According to their order of decreasing wavelength and increased energy they are classified as follows.
RADIO WAVE, MICRO WAVE, INFRA-RED, VISIBLE LIGHT, ULTRAVIOLET RAY, X-RAY, GAMMA RAYS.
Answer: Answer Below
Answer below
Explanation:
Some appliances - such as vacuum cleaners and electric drills - do not have an earth wire. This is because they have plastic casings, or they have been designed so that the live wire cannot touch the casing. ... These appliances have double insulation.
