What is the difference between Business model based software requirements analysis and Domain model based software requirements analysis?
Come to CSE and you'll know ;)
What is the difference between volumetric analysis and gravimetric analysis?
AnswerVolumetric analysis or titration is a common laboratory method of chemical analysis which can be used to determine the concentration of a known reactant; volumetry is a quantitative method of analysis.Qualitative analysis is used to separate and detect elements, functional groups, molecules etc. in a sample substance, without specifying concentration.
Matrix applications in electronics and communication?
Matrices are mainly used in network analysis to solve problems based on mesh and nodal analysis. Their applications are also used in network topology to solve problems based on tie set, cut set and incidence matrix.
What is a testing method based on an analysis of the specification of a piece of software without reference to its internal workings?
Black Box Testing
What material improved transistors?
The introduction of silicon as a semiconductor material significantly improved transistors, especially with the development of silicon-based integrated circuits. Silicon's favorable electronic properties, abundance, and ease of doping with impurities allowed for greater control over electrical conductivity. This advancement led to the miniaturization of electronic components and the proliferation of modern electronics. Additionally, materials like gallium arsenide and more recently, graphene and other 2D materials, have further enhanced transistor performance in specific applications.
A silicate mineral must contain?
A silicate mineral must contain silicon and oxygen as its primary components. These elements form the building blocks of silicate minerals, with other elements such as aluminum, iron, magnesium, and calcium often present in smaller quantities. Silicate minerals are the most abundant mineral group on Earth and have a structure based on silicon-oxygen tetrahedra.
What are the elements found in sand?
Sand is primarily composed of silicon dioxide (SiO2), commonly known as quartz. Other elements found in sand include feldspar, mica, shell fragments, and mineral particles. The exact composition of sand can vary based on its source and location.
What provides the framework for all silicate minerals?
Silicate minerals are based on a fundamental building block called the silicon-oxygen tetrahedron, which consists of a silicon atom bonded to four oxygen atoms in a pyramid-like structure. These tetrahedra link together in various arrangements to form the framework structure that is characteristic of silicate minerals.
Based on its abundance in the earth's crust most rocks contain a mineral composed of the elements oxygen and what else?
Most rocks contain minerals composed of the elements oxygen and silicon. This is because silicon is one of the most abundant elements in the Earth's crust and forms the backbone of many common rock-forming minerals.
Silicon and oxygen combine to form the framework of the most common mineral group?
Silicon and oxygen combine to form the framework of the most common mineral group known as silicates. These minerals make up about 90% of the Earth's crust and can have various structures based on how the silicon and oxygen atoms are arranged. Examples include quartz, feldspar, and mica.
What does silicon bond with?
Silicon typically forms bonds with oxygen to create silicon dioxide, commonly known as quartz or silica. It can also bond with other elements like carbon, hydrogen, and various metals to form a wide range of silicon-based compounds.
Why is silicon dioxide sio2 and not sio4?
1) di stands for two 2) silicon has 4 valence electrons & oxygen has 2.
Is a silicone an element?
No. Although it is a subject of great confusion in the public at large.The element is silicon, element number 14, a large constituent of quartz and of sand, and therefore of many types of glass.The substance silicone is any of several rubbery materials, originally polydiphenylsiloxane (Ph2SiO, which is based on phenyl molecules). Related organic molecules are called polymerized siloxanes.
What does an O2 sensor do on a car?
It detects the amount of oxygen in the exhaust gas compared to the outside air. Most are made with a closed-end tub of cermic zirconia, the zirconia genreates an electrical signal that is sent to the car's main computer (ECU or ECM). The computer adjusts the amount of fuel injected into the engine based partially on the signal coming from the O2 sensor.
Both continental crust and oceanic crust consist mainly of what elements?
Both continental crust and oceanic crust consist mainly of silicon and oxygen, forming silica-based minerals. However, oceanic crust tends to have higher concentrations of iron and magnesium compared to continental crust.
What is the major element in the sand?
SiO2--silicone dioxide, or silica. Interestingly, oxygen, and then silicone, are the two most abundant elements in the Earth's crust, with approximately 60.1% being oxygen and 20.1% being silicone.
Are most molecules found in the giant molecular clouds are based on silicon?
No, most molecules found in giant molecular clouds are not based on silicon. Instead, they are primarily composed of elements like hydrogen, helium, carbon, oxygen, and nitrogen, which are more abundant in the universe. Silicon-based molecules are less common in interstellar environments.
