Scientists use a variety of methods, such as microscopy, spectroscopy, chromatography, and mass spectrometry, to identify physical changes in materials. These techniques help scientists observe changes in the size, shape, structure, composition, or properties of a substance, allowing them to understand how physical changes occur at a molecular level.

What are the common methods used for the resolution of vectors problems?
Common methods used for resolving vector problems include graphical methods, algebraic methods, and trigonometric methods. Graphical methods involve drawing vectors on a coordinate plane, algebraic methods involve using equations to manipulate vector components, and trigonometric methods involve using trigonometric functions to find vector magnitudes and angles.
How can the density of an irregular object be calculated?
The density of an irregular object can be calculated by dividing its mass by its volume. To measure the mass, you can use a scale, while the volume can be determined through methods like water displacement or mathematical calculations based on its shape. Once you have these values, divide the mass by the volume to find the density.
Why scientist find the particle theory of matter useful?
Scientists find the particle theory of matter useful because it helps explain the behavior of matter on a small scale, such as the properties of atoms and molecules. It also provides a framework for understanding various phenomena, such as changes in state and chemical reactions. Additionally, the theory allows for predictions and control of these processes, leading to advancements in technology and scientific research.
What are the different methods of determining the resultant of vector?
The two main methods for determining the resultant of vectors are the graphical method, where vectors are drawn to scale and added tip-to-tail to find the resultant, and the component method, where vectors are broken down into their horizontal and vertical components which are then added separately to find the resultant.
Why do scientists use a variety of methods when investigating science?
to find out more about it
What is a scentific methods?
A scientific method is a process used by scientists to find answers to questions or solve a problem.
What evidence do scientists find in fossils and living things?
Scientists find evidence in fossils and living things such as changes in morphology, genetic similarities, and transitional forms that support the theory of evolution. Fossils can show physical adaptations over time, and living organisms can reflect common ancestry through shared genetic traits. These pieces of evidence help scientists to understand the evolutionary history and relationships between different species.
Why must a combination of methods be used to study human genetics?
When studying anything with the depth that scientists are studying DNA sometimes it takes several different methods to find the information that is being seeked.
What other data besides physical features do scientists use to find if organisms are related?
behavior, embryology, and DNA.
How do scientists use scientific method to solve problems?
they are scientists so they use science for god sake they are smart
What is the name of a disorder where you cant find any physical changes to explain symptoms?
inorganic disorder
How do scientists find things out?
Scientists find things out by doing experiments.
What is it called when a scientists has to restart a experiment?
A waste of money and resources ..... You may also have to restart/rerun an experiment when you find out your methods of evaluating the test results do not fit or your hypothesis was wrong :-(
