The Diagram Shows A Generator Powered By A Water Turbine. Based On The Diagram, What Type Of Energy Transformation

Answers

Answer 1
Answer: C

Explanation:
Answer 2

The transformation takes place in the generator is mechanical energy is transformed into electrical energy.  Hence option A is correct.

What is energy transformation?

Energy transformation is defined as the conversion of energy from one form to another. The passage of energy from one place to another is known as energy transfer. When energy transforms, it goes from one type to another.

Hydroelectricity is a type of renewable energy that produces electricity by harnessing the force of moving water. Mechanical energy is transformed into electrical energy in a generator. Most generators create alternating current as their source of electricity. A generator spins when a turbine's blades rotate due to falling water, converting the mechanical energy of the spinning turbine into electrical energy.

Thus, the transformation takes place in the generator is mechanical energy is transformed into electrical energy.  Hence option A is correct.

What type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom?

Answers

Then as the electrons in the atoms fall back down, they emit electromagnetic radiation (light). The amount of light emitted at different wavelengths, called the emission spectrum, is shown for a discharge tube filled with hydrogen gas in Figure 12.6 below.

The type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom is hydrogen spectrum.

What is hydrogen spectrum?

The hydrogen spectrum is given by the scientist Bohr and it consist of series name lyman, balmer, paschen, bracklet and p- fund as the electromagnetic radiations splits into this.

The lyman series is formed when electrons jumps from any hige energy level to n = 1 and will be same for balmer , pachen ,bracklet and p-fund are obtained when electrons jumps from any higher energy level to n = 2,3,4 and 5 respectively.

What is a mixture?

A mixture is when two or more substances mix with each other without participating in a chemical change. The combining substance does not lose its properties or individuality in a mixture.

In other words, the components of a mixture each keep their original properties.

Since mixtures are chemically combined, they can be easily separated by physical means.

Examples of a mixture are crude oil, air, seawater, and gun powder.

The amplitude​ of a wave is related to the energy of a wave. Did you see anything on the screen that made you think this or could prove your point? How could you demonstrate this relationship?

Answers

Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

Explanation:

The amplitude​ of a wave is directly related to the energy of a wave.

What is amplitude?

Amplitude is the maximum distance covered by a body from the main point in the vibrating mode.

As we know that energy of the wave is directly proportional to the square of the amplitude:

E ∝ (a)²

As the amplitude of wave increases, energy carried by the wave is also increases. Higher energy increases the amplitude of the propagating wave.

Answers

Exothermic reaction = the term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity,

Endothermic reaction = An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Answer:

An exothermic reaction is a chemical reaction that releases heat energy to the surroundings. This means that the overall energy of the products is lower than the overall energy of the reactants, resulting in a net release of energy in the form of heat. This can be observed as an increase in temperature of the surroundings or an increase in the motion of the reactant particles, as they absorb the energy that is released. Examples of exothermic reactions include combustion, oxidation, and many biochemical reactions.

Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations?

It is not smooth or rough surfaces that affects friction. It is the size of the push.
When an object moves across a rough surface, there is no friction.
When an object moves across a smooth surface, the friction increases.
When an object stops moving, there is no friction.

Answers

No surface is completely smooth, friction happens. There is higher friction between rougher surfaces. So, it is the wrong statement that smooth or rough surfaces do not affect friction.

What is friction?The resistance to motion of one object moving in relation to another is known as friction. It is not regarded as a fundamental force like gravity or electromagnetic.The interplay of small bumps on the surfaces of objects as they rub together is thought to be the primary source of friction, though scientists are not entirely certain of this. Particles that stick out above the rest can be found on even the most smooth surfaces. As the objects move, these high points collide and scrape against one another, creating resistance. Friction is brought on by this unwillingness to move.Sliding friction, fluid friction, and rolling friction are the three primary categories into which friction can be categorized. The items that are moving and the force being applied to them determine the type of friction.
