Answer:
So the resonance phenomenon is what allows for notes to be produced on a musical instrument at all. A guitar though makes an additional use of resonance. The body of the guitar is carefully designed to resonate when notes are played on the strings. The reason is that the body can then behave as an amplifier for the strings.

Why was the International System of Units chosen?
please answer this soon
Answer: The SI system is easier and more consistent. If the Klingons in the next galaxy know the definitions of metric, they can replicate the measures on their own planet. With English, they'd need to grab a yardstick the next time they did a crop circle.
Explanation: I'll use "SI" for the International System of Units. There are several key benefits;
Unlike the English system, there are base units that form a standard for various measures: length (meter), mass (kg), Time (sec), electric current (Ampere), temperature (Kelvin), amount of a substance (moles), and candela (luminous intensity). A system of prefixes allow the base unit to be easily changed to accomodate larger and smaller quantities. 1,000 grams is 1 kg. 1000 meters is a kilometer (km), etc. In English, it isn't so easy. An English unit of measure may read "1 mile, 34 yards, 2 feet, and 6 and 1/8 inches." In metric it would simply read 1698.5 meters, or 1.698.5 km. Imagine the difference in finding the area of a rectangle in English vs metric: Either 1) 2ft, 3 and 13/16" times 4ft, 8 and 1/16 inches, or 2) 1.833 meter by 2.877 meter.The metric system has standards that allow a high degree of calibration. Distance is calibrated to the speed of light and time is calibrated tio a vibrating atom, for example.what is the volume of a piece of metal that has a density of 6.68g.cm^3 and has a mass of 1975 g?
Answer: 296 grams/cm^3 (3 sig figs)
Explanation: Divide the mass by the volume to get grams/cm^3.
do all types of energy have the same amount of energy
Answer:
Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth.

Which of the following diagrams shows a pure substance that is composed of only individual atoms and not molecules?
Answer:
Ar
Explanation:
the last one
The diagram that shows a pure substance which is composed of only individual atoms and not molecules will be: argon gas. Option D is correct.
A pure substance composed of only individual atoms is called an element. In the periodic table, each element is represented by a unique symbol, and its atoms cannot be further broken down into simpler substances by chemical means.
Liquid water: Water (H₂O) is a compound composed of two hydrogen atoms bonded to one oxygen atom. It consists of molecules, not individual atoms.
Hydrogen gas: Hydrogen gas (H₂) is composed of two hydrogen atoms bonded together to form a diatomic molecule. It is not composed of individual atoms.
Carbon dioxide GAS: Carbon dioxide (CO₂) is a compound consisting of one carbon atom bonded to two oxygen atoms, forming a molecule of CO₂.
Argon gas: Argon (Ar) is an element, and in its pure form as a gas, it exists as individual argon atoms (Ar). It is not bonded to any other atoms, and there are no molecules involved. Therefore, argon gas is composed of individual atoms and represents a pure substance.
Hence, D. is the correct option.

Which of these could be a measurement of an object’s mass?
a. 24 newtons
b. 24 grams per milliliter
c. 24 meters
d. 24 grams
Answer:
Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance.

Answer:what grade this is
Explanation:
Write 0.034 in scientific notation.
Answer:
0.034 = 34×10^-3
Explanation:
This is because the special point is notated until it goes in front of the first counting number
Scientific notation is a way of expressing numbers that are very large or very small in a compact and standardized format. 0.034 in scientifc notation is written as 3.4 × 10⁻³
In scientific notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is a decimal number greater than or equal to 1 but less than 10, and the power of 10 represents the magnitude of the number. The power of 10 indicates the number of places the decimal point must be moved to obtain the original number.
For example:
The number 4,500,000 can be written in scientific notation as 4.5 x 10⁶, where the coefficient is 4.5 and the power of 10 is 6.
The number 0.000043 can be written in scientific notation as 4.3 x 10⁻⁵, where the coefficient is 4.3 and the power of 10 is -5.
Scientific notation allows for easy representation of very large or small numbers and simplifies calculations involving these numbers. It is particularly useful in scientific fields where values such as distances, masses, and concentrations can vary over a wide range.
