=YES RED UNSCENTED CANDLES BURN FASTER THAN WHIT UNSCENTED CANDLES!=

Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them. The occurrence of ionization depends on the energy of the impinging individual particles or waves, and not on their number. An intense flood of particles or waves will not cause ionization if these particles or waves do not carry enough energy to be ionizing. Roughly speaking, particles or photons with energies above a few electron volts (eV) are ionizing. Examples of ionizing particles are energetic alpha particles, beta particles, and neutrons. The ability of electromagnetic waves (photons) to ionize an atom or molecule depends on their wavelength. Radiation on the short wavelength end of the electromagnetic spectrum - ultraviolet, x-rays, and gamma rays - is ionizing.

electromagnetic waves are produced by the motion of electrically charged particles. electromagnetic waves are also called electromagnetic radiation because they radiate from electrically charged particles.

No, something cannot be both a pure substance and a mixture. A pure substance is made up of only one type of atom or molecule, while a mixture is made up of two or more different substances physically combined.

Sea water is more dense than fresh water because it contains dissolved salts, minerals, and other substances that increase its mass without significantly increasing its volume. This increased mass causes sea water to be more dense than fresh water, which has a lower concentration of dissolved substances.

Starting friction is the force required to overcome the initial static friction and get an object moving, while sliding friction is the force that opposes the motion of an object already in motion. Starting friction is typically higher than sliding friction.

My hypothesis for my experiment was that rubbing the balloon on the wool sweater will make the balloon stay on the desk the longest. I believe this because the sweater was furry. I also predicted that there would not be a different in the amount of time the balloon stayed on the desk at different times of day.

If I am not wrong..this is what I learnt in chemistry.

When a liquid is being frozen, the particles of that liquid will lose kinetic energy and slow down, causing them to move closer together. Thus, as the gaps between the particles decrease and the particles themselves get into a fixed position, it becomes a solid & the particles [only] vibrate in their fixed position. =D

Impulse is the product of force and time, measuring the change in momentum over a period of time. Impact force, on the other hand, is the force experienced by an object during a collision or contact event, typically involving a sudden change in momentum over a short period of time. Impact force is a component of impulse, as it contributes to the overall change in momentum.

An inclined plane is an example of a simple machine with no moving parts. It works by allowing a force to be applied over a longer distance to move an object to a higher or lower elevation. It reduces the amount of force needed to move an object by increasing the distance it travels.

Ionization is the process by which an atom gains or loses one or more electrons, resulting in the formation of charged particles called ions. Forms of nuclear radiation capable of ionizing matter include alpha particles, beta particles, and gamma rays, due to their high energy levels that can remove electrons from atoms when they interact with them.

IT measures it by the alcohol or mercury being touch by heat so the fluid rises.There is a chemical in the thermometer (the red liquid ) and it reacts to heat or coldness. cold makes it retract and the heat makes it expand

That is NOT a deformation thermometer but an expansion thermometer. A deformation thermometer has a bimetallic strip. This is a strip made by joining together two strips of metal with very different coefficients of thermal expansion. When heated, one of the metals expands much more than the other. But, because they are bonded together it is not permitted to expand freely and as a result the bimetallic strip is deformed. The amount of deformation is converted to a temperature scale for display.

No, sand does not dissolve in tea. Sand is insoluble in water, which means it will not dissolve or mix with liquids like tea. If sand is present in tea, it will settle at the bottom and can be easily separated by filtration.

A hypothesis is a prediction about the outcome of a test or experiment. It is an educated guess based on existing knowledge or observations, and is used to guide scientific investigations.

Bakery bread is typically fresher and made with higher quality ingredients than store-bought bread, resulting in better taste and texture. Bakery bread also offers a wider variety of flavors and artisanal options compared to the standard options available in stores.

When you hold a match over the wick, a small amount of wax melts then burns starting a cycle. The candle flame melts solid wax into a liquid, and the liquid is absorbed into the wick and burns. Candles are essentially a modernized lantern relying on solid fuel instead of oil.

Currently, artificial gravity as seen in science fiction movies (such as spinning habitats to create centrifugal force) does not exist in the same way. However, there are ongoing research and experiments exploring how artificial gravity might be simulated for long-term space missions to help counteract the negative effects of microgravity on the human body.

The work done by the engine is equal to the change in potential energy. The change in potential energy is given by the formula mgh, where m is the mass of the truck, g is the acceleration due to gravity, and h is the height difference in meters. Substituting in the given values, we have (3500kg * 9.8 m/s^2 * 200m) = 6,860,000 J.

People study physics to understand the fundamental principles that govern the behavior of the universe, such as how matter and energy interact. It helps us explain natural phenomena, develop new technologies, and make predictions about the world around us. Physics also lays the groundwork for other scientific disciplines and has practical applications in many industries.

Yes, that's one of the things used in any experiment with voltage and hair, pickles, onions, etc for experiments and such. The Tesla coil provides different levels of voltage depending on its size and generator.

Tarnished silver can usually be easily cleaned using silver polish or a mixture of baking soda and water. However, if the tarnish is severe or the item is valuable, it may be best to seek professional cleaning or restoration services to avoid damaging the silver. Regularly polishing and storing silver properly can help prevent tarnishing in the future.

Brass is composed primarily of copper and zinc. The exact composition may vary depending on the specific type of brass, but typically contains around 60-70% copper and 30-40% zinc.

You could make multiple paper planes, but wiht diffrent wing spans. YOu can do this by cutting the wings. You could also have diffrent shaped paracutes and send them down flying. Use toys connected to a something to use as a parachute. Diffrent parachute shapes can be circles, squares, rectangles, and triangles. Fell free to add more shapes. I hope this helps you people! :)
