Final answer:

The substance with the lowest specific heat will heat up the fastest. (option C) Gold would heat up the fastest among copper, aluminum, gold, and iron.

Explanation:

In this case, the substance with the lowest specific heat will heat up the fastest when subjected to the same amount of heat. Specific heat is the amount of heat needed to raise the temperature of a given mass of a substance by 1 degree Celsius. So, the substance with the smallest specific heat value will heat up faster.

Based on their specific heat values, copper has a specific heat of 0.39 J/g °C, aluminum has a specific heat of 0.897 J/g °C, gold has a specific heat of 0.129 J/g °C, and iron has a specific heat of 0.449 J/g °C. Therefore, gold would heat up the fastest among these substances.

In summary, considering substances with the same mass and heated by the same amount,  (option C) gold would heat up the fastest.

The true statement about energy is that according to the conservation of energy, the total energy of an isolated system remains constant, even though it can change form.

Understanding the Conservation of Energy.The statement concerning energy that is true is that the total energy is constant in any process. Energy is defined as the ability to do work and is measured in joules. According to the law of conservation of energy, energy can neither be created nor destroyed. It can change from one form to another, but the total energy of an isolated system remains constant. For example, kinetic energy, which is energy due to motion, can be converted to potential energy, or vis versa, but the sum of both will remain unchanged in an isolated system.

An essential principle to recall is that no matter how energy is transformed or transferred, the total amount of energy in the universe remains constant. This principle is known as the conservation of energy, which is a fundamental concept in physics.

The correct option is C

Explanation:

The negative impact of kevlar in the society is that it can not just be disposed via conventional methods. It's resistance to flame and  and high temperature means burning it will not dispose it. Also, its water resistant property means kevlar will obstruct drainages if thrown in the drainage - because when it piles up, water will not be able to pass through it hence obstructing the flow of water. It being difficult to cut, with its low reactivity and it's non-corrosive property means it will be very difficult and expensive to dispose

Alexandra needs to take 3 nutrition bars with her for the trip.

To calculate the number of nutrition bars Alexandra needs to take with her, we need to determine the total energy provided by each bar. According to the label, each bar contains 50 g of carbohydrates, 10 g of fat, and 40 g of protein. To calculate the energy content, we can multiply the amount of each nutrient by the energy value per gram. Carbohydrates and proteins provide 4 kilocalories (kcal) per gram, while fats provide 9 kcal per gram.

Energy from carbohydrates: 50 g * 4 kcal/g = 200 kcal

Energy from fat: 10 g * 9 kcal/g = 90 kcal

Energy from protein: 40 g * 4 kcal/g = 160 kcal

Total energy per nutrition bar: 200 kcal + 90 kcal + 160 kcal = 450 kcal

To determine the number of bars Alexandra needs, we can divide the total energy required for the trip (1350 kcal) by the energy provided by each bar.

Number of nutrition bars needed: 1350 kcal / 450 kcal/bar = 3 bars

Answer:

irreversible change

Explanation:

It is an irreversible process, since when the green powder is heated and turns black, producing a gas, new chemical compounds are formed. A similar example is the reaction to the decomposition of copper carbonate, which is heated to produce carbon dioxide. The reaction is as follows:

CuCO3 (g) → CO2 (g) + CuO (s)

Sound waves are the waves generated from the sound source and are composed of rarefactions and compressions, they are of longitudinal, pressure and mechanical wave types.

A fish swimming 5 m below the surface of the water will hear the sound first.

A sound travels in a medium depending upon the amplitude,  time period, frequency, velocity and wavelength.

A sound wave travels faster in the water as the particles are closely packed compared to the air and the water is denser as compared to the air.

The particles in the air are loosely and distantly placed making them less dense and hence the sound travels slower in the air.

Therefore, fish will hear the sound first.

Final answer:

The mL increment to pull the plunger for each reading depends on the experiment's needs; for a 50 mL syringe, one might use 5 mL or 10 mL increments for convenience and ease of measurement.

Explanation:

To answer the question regarding how many milliliters (mL) you would need to pull the plunger of a syringe for each reading, it's crucial to understand that this will depend on the specific requirements of the experiment or what the experiment is aiming to measure. If no specific increments are given in the experiment details, a common approach is to pull the plunger in regular intervals that make sense for the total volume of the syringe and the level of precision required. For example, if you are using a 50 mL syringe, you might choose to pull the plunger 5 mL at a time to obtain ten readings for the full range, or 10 mL at a time for five readings, as these increments allow for relatively easy reading and measurement.

As the puck falls, its kinetic energy increases. Therefore, the correct statement is option B.

As the puck falls, its kinetic energy increases. This is due to the conversion of potential energy (stored energy due to the puck's position above the ground) into kinetic energy (energy of motion). As the puck falls, it gains speed and its kinetic energy increases.

Kinetic energy is the energy of motion that an object possesses. According to law of conservation of energy, energy cannot be created or destroyed, it can only be transferred from one form to another. As the puck falls, its kinetic energy increases due to the conversion of potential energy into kinetic energy (energy of motion).

A combustion reaction involves a substance reacting with oxygen to release energy, distinct from other chemical reactions by the presence of oxygen and energy production. Examples include the burning of methane or hydrogen gas, providing essential energy for society.

A combustion reaction is a specific type of chemical reaction where a substance combines with oxygen (O₂) and releases energy in the form of light and heat. This is different from other chemical reactions because combustion specifically involves oxygen as a reactant and the production of energy. For example, the combustion of methane on a kitchen stove is represented by the equation CH₄ + 2O₂ → CO₂ + 2H₂O + Heat, where methane (CH₄) reacts with oxygen, producing carbon dioxide, water vapor, and heat. Other notable examples include the combustion of hydrogen gas, which produces water vapor: 2H₂ (g) + O₂ (g) → 2H₂O(g). Combustion reactions are essential in providing the energy that powers our societies, such as in producing electricity, transportation, and heating, but they are also a major contributor to global climate change.

Answer: change in velocity of light at the boundary between two media.

Explanation:

The speed of light changes at the air-glass or air-water boundary. The speed of light in air is different from the speed of light in glass or water. Hence, as light approaches the interface of the two media, its speed changes accordingly thereby causing the light rays to bend at the interface of the two media. This bending of light is called refraction.
