Yes, the sun is nonliving. It has no independent thought or control over what it does for eternity. It is just a giant ball of burning gas. Although, it is the creator of life as it provides light and heat for Earth.
Does light travel faster than sound?
No. Sound is a conductive vibration that travels more slowly than light in any real-world environment. Sound travels at about 1,100 feet per second in air, and light travels at 186,000 miles per second in a vacuum and nearly as fast in air (although not as fast in glass, diamond, or other transparent solids). The large difference in speed is why you see a flash of lightning before you hear the thunder it creates.
Sound is created by a wave that essentially pushes particles into the next particle. The speed of this wave is determined by the material it is traveling through. Something with high density and rigidity, such as steel, conducts a sound wave considerably faster than air (20,000 feet per second). If you were to have an object of infinitely high density and rigidity, sound could travel as faster as light. However, because it still boils down to the maximum velocity of the particles in the wave, it would not be able to exceed the speed of light.
What are the advantages and disadvantages of oil lamps?
Advantages of oil lamps include providing a soft, warm light, being portable, and having a long burn time. However, disadvantages may include the risk of fire hazards, the need for refilling oil, and the potential for soot and smoke buildup.
What light packs the highest energy per photon?
The highest energy per photon is found in gamma rays, which are a form of high-energy electromagnetic radiation. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum.
A well-defined group of objects that transfer energy to one another?
A system is a well-defined group of objects that transfer energy to one another. This transfer can take place as a result of mechanical work, heat, or electromagnetic radiation within the system. Systems can be open, closed, or isolated depending on the exchange of matter and energy with their surroundings.
What device changes gravitational potential to kinetic energy?
A simple example would be a roller coaster. As the coaster climbs up a hill, potential energy due to its height increases. When it goes down the hill, this potential energy is converted to kinetic energy as the coaster gains speed.
What causes geothermal energy?
Geothermal energy is caused by the heat stored beneath the Earth's surface, mainly from the decay of radioactive materials in the Earth's core. This heat can be accessed through wells drilled into the ground and used to generate electricity or for direct heating purposes. Geothermal energy is a renewable and sustainable source of power.
What kind of energy increases as its height decreases?
nutition provides with energy to liv better and grow. So if you eat as followed in the food pyramid, you should big and strong... don't you agree
As the sun warms the Earth's surface, the atmosphere warms too. Some parts of the Earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air which weighs less them cool air rises. The cool air moves and replaces the rising warm air. This movement of air is what makes the wind blow.
Wind is caused by uneven heating of the Earth's surface. Moist air is less dense than dry air, and areas the of high pressure (moist air) rush into the areas of lower pressure (dry air), causing wind.
When might kinetic energy turn into sound energy?
Kinetic energy turns into sound energy when an object in motion interacts with air molecules, causing them to vibrate and create sound waves. This can happen when an object moves quickly or collides with another object, converting its kinetic energy into sound energy.
What is the effects of human activities on soil pH?
Human activities such as agricultural practices, industrial activities, and urbanization can lead to changes in soil pH. For example, the use of fertilizers and pesticides in agriculture can increase soil acidity, while activities like mining and construction can release pollutants that alkalize soil. These pH changes can impact the soil's ability to support plant growth and can disrupt soil ecosystems.
There are (at least) four methods for production of hydrogen.
(1) The cheapest method is steam reforming of methane:
CH4 + H2O --> CO + 3 H2
(2) An environmentally friendly, but not very efficient method is electrolysis of water, using a dilute sulfuric acid electrolyte:
4 H2O + 4 e- --> 2 H2 + 4 OH- ; 2 H2O --> O2 + 4 H+ + 4 e-
(3) The original Cavendish method of hydrogen production involves reaction of red-hot iron with steam.
(4) A convenient method for producing a small amount of hydrogen as economically as possible is the reaction of iron with dilute sulfuric acid.
How is temperature and thermal energy different?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. Temperature is an intensive property, meaning it does not depend on the amount of material present, while thermal energy is an extensive property, meaning it does depend on the amount of material present.
What gases are produced when natural gas is burnt?
If you acheive perfect combustion then only CO2 and water are produced. If there is not the right ratio of fuel to air or if there is other substances in the gas then you could end up with carbon monoxide, oxides of nitrogen, or sulfates that produce acid rain.
What is a measure of average kinetic energy of a group of molecules?
The temperature of a sample of nitrogen gas is a measure of the molecules' average # activation energy # potential energy # kinetic energy # ionization energy Answer 3 Reason Temperature measures average kinetic energy.
Mold obtains energy through the process of breaking down organic matter by secreting enzymes to digest it. This allows mold to absorb the nutrients necessary for its growth and reproduction.
When a cell has energy available how can it store amounts of that energy?
When a cell has energy available, it can store small amonts of energy by adding a third phosphate group to ADP, producing ATP.
I got this answer from my textbook (9th grade). It is 100% right. :D
What is kinetic energy and potential energy combined?
The sum of kinetic energy and potential energy is called mechanical energy. Mechanical energy represents the total energy of an object due to its motion and position. It is conserved in the absence of non-conservative forces like friction.
Energy not in Motion. A good battery has the pontential to light a light bulb. Your house AC outlets have potentional voltage there at the socket to power up your home appliances. A strectched rubber band has stored potential to hurt you if you don't know how to flip it at you target.
How does a hybrid take the kinetic energy of a moving vehicle and turn it into potential energy?
A hybrid car uses regenerative braking to capture the kinetic energy of a moving vehicle and convert it into electrical energy. When the car brakes, the electric motor works in reverse to slow down the car and generate electricity, which is then stored in the battery as potential energy for later use.
What is the cellular movement of a substance that requires the use of energy?
Active transport is the cellular movement of a substance that requires the use of energy, typically in the form of ATP. This process involves the movement of molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.
Where is geothermal energy being used?
Geothermal energy is being used extensively in NZ to produce power,
Many countries in the world, especially Iceland and New Zealand are using geothermal energy.
Geothermal energy is used in cooling and heating devices, like thermostats, and heating vents. They are also used in some greenhouses.
California uses the most geothermal energy in the US. In 2013, the Golden State used over 80 percent of the geothermal energy used nationwide. Nevada is second with 15 percent.
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
How do you generate electricity from oil?
Three technologies are used to convert oil into electricity:
