______ is a way to describe matter with numbers and units.
Measurement is a way to describe matter with numbers and units.
Measurement is a fundamental process used to describe and quantify various aspects of matter. It involves assigning numerical values to physical quantities and expressing them using appropriate units of measurement.
In scientific and everyday contexts, measurements provide a standardized and consistent way to communicate information about the properties, dimensions, quantities, and characteristics of objects, substances, or phenomena. By using measurements, we can describe the size, length, mass, volume, temperature, time, and many other attributes of matter.
The process of measurement typically involves two components: a numerical value and a unit. The numerical value represents the magnitude or quantity being measured, while the unit provides the reference or scale by which that quantity is expressed. Units help provide meaning, context, and comparability to measurements.
Hence, measurement provides a quantitative and objective way to describe matter, allowing us to understand and interact with the physical world in a systematic and meaningful manner.

The period of time needed for a radioisotope to lose one-half of its activity is known as that isotopes
Explanation:
The radioactive scattering technique is called radioactive degradation. For each radioactive isotope, the natural radioactive cycle is special and is determined by a period of time termed a half-life. One half-life was its time needed to experience radioactivity for half of both the radioactive nuclei.

Which group in the food chain uses the energy of the sun to create its own food A consumers B predators C producers D prey
Answer:
C producers
Explanation:
All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

how does the law of conservation of mass applies to all chemical reactions?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Describe what happens inside a CD
player when you listen to an audio CD.
The thing that happens inside a CD player when you listen to an audio CD is that laser beam turns on and scans along a track with the photocell from the CD's center.
What are semiconductors?The electrical conductivity of a semiconductor material is between that of a conductor, such as metallic copper, and that of an insulator, such as glass.
A small photoelectric cell and a smaller laser beam (called a semiconductor diode laser) are found inside your CD player (an electronic light detector). When you hit play, the disc is rotated at a high speed by an electric motor (not visible in this figure) (up to 500rpm).
The laser beam turns on and scans along a track with the photocell from the CD's center to its edge (in the opposite way to an LP record). As the laser/photocell scans from the center to the periphery of the disc, the motor gradually slows it down (as the track number increases, in other words).
Hence laser beam turns on and scans along a track with the photocell from the CD's center.
