What else can I help you with?
Ask us anythingWhich must be true for metamorphism to occur?
Metamorphism occurs when rocks are exposed to high temperatures, pressure, or chemical fluids beneath the Earth's surface. These conditions cause the minerals within the rock to recrystallize, resulting in new mineral assemblages and textures. The original rock remains solid during this process.
What is yield stress?
Yield stress is the point at which the material is no longer linear under load; the material starts to become plastic and when unloaded will not return to its original length. Typically the yield point is defined as 0.2% offset - the value of strain that remains in the part after unloaded
What is loose material such as bits or rock minerals and plant and animal remains called?
The loose material is called sediment. It may include bits of rock, minerals, and organic material like plant and animal remains. This sediment can accumulate in layers over time and eventually become sedimentary rock through processes like lithification.
What was marble before it was altered by heat and pressure?
Marble was originally limestone, a sedimentary rock made primarily of calcite minerals from the remains of marine organisms. Heat and pressure from geological processes turned the limestone into marble through the process of metamorphism.
Is coal considered an organic material?
Yes, coal is considered an organic material because it is formed from the remains of plants and other organic matter that have been compressed and heated over millions of years.
What happens in young modulus of elasticity of material when load hanging onit is doubled?
When the load hanging on a material is doubled, the young modulus of elasticity remains constant. Young's modulus is a material property that measures its stiffness and is independent of the applied load. It represents the material's ability to deform elastically under stress without permanent deformation.
What is the study of material remains?
Study of cilization through the material remains is archaelogy
What is Difference between elastic limit and proportional limit?
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.
Hookes law hold well up to?
Hooke's law describes the relationship between the force applied to a spring and the resulting extension or compression of the spring, as long as the material remains in the elastic deformation range of the stress-strain curve. Beyond the elastic limit, the material may exhibit plastic deformation, and Hooke's law may not apply.
What physical property changes when aluminum can is crushed?
When an aluminum can is crushed, its shape changes due to deformation but the chemical composition of the aluminum remains unchanged. The volume of the can decreases, resulting in a higher density due to the material being compressed.
How does the spring constant change when a greater force is applied?
When a greater force is applied, the spring constant remains constant for an ideal spring. However, in real springs, the spring constant may change slightly due to factors like deformation or material properties.
When the cardboard is at rest (answer)?
When the cardboard is at rest, it is not undergoing any motion or change in position. It is stationary and its position remains constant.
What is the difference between proportional limit and elastic limit?
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.
What is the material that remains after reabsorption?
The material that remains after reabsorption in the kidney is urine, which contains waste products, excess ions, and water that were not reabsorbed back into the bloodstream.
What are human material remains?
Human material remains are physical remnants of a person's body after death, such as bones, teeth, or hair. These remains can provide valuable information about an individual's identity, health, and lifestyle to archaeologists, anthropologists, and forensic scientists. Studying human material remains can help researchers understand the past societies and individuals.
What Material with a shape that remains unchanged when it is moved from one container to another?
solid material
What is MR 7 material?
"MR 7 material" remains undefined in the English language.
