What else can I help you with?
How does having constraints placed on a design change the engineering process?
The change between design and engineering process is long. The process of this is time, quality and budget.
What is the expression for Electrostatic deflection sensitivity?
theta is directly proportional to: (square of V) * (rate of change of C w.r.t. theta) i have given this answer in relation to Electronics measuring instruments.
What is a quasi equilibrium. What is its importance in engineering?
When a process proceeds in such a manner that the system remains infinitesimally close to an equilibrium state at all times, it is called a quasi-static or a quasi-equilibrium process. A quasi-equilibrium process can be viewed as a sufficiently slow process that allows the system to adjust itself internally so that properties on one part of the system do not change any faster than those other parts. Engineers are interested in quasi-equilibrium process for two reasons. Firstly, they are easy to analyze. Secondly, work-producing devices deliver the most work when they operate on quasi-equilibrium processes. Engineer Ebrahim Anwar Kisswani.
What is the difference between leveling and surveying?
Surveying measures angles and distances, usually in three dimensions. Leveling only meaures the elevation change between two or more points. One of the crudest leveling instruments is simply a hose filled with water. If the two ends of the hose are held at the same height, no water flows out. If one end is lower, the water flows out that end.
When water leaves a body of water after it is heated the process is called?
The process by which water leaves a body of water after it is heated is called "evaporation." This occurs when the water molecules gain enough energy from the heat to break their bonds and transition from a liquid to a gaseous state. The resulting water vapor rises into the atmosphere, where it can eventually condense and form clouds, leading to precipitation and the cycle of water.
What is manual manipulation?
Manual manipulation is to interfere with a naturally occurring process and change it to benefit our needs
Why does the phase change graph show a flat line during the phase change?
It is because that is when the change is occurring, and the diagonal part is when the process has already happened
What is a change step?
A change step is a change that occurs in a process suddenly, without warning. The change is so drastic from the normal standard that the process needs to be changed to accommodate the difference.
Observed the process of transformation when he was studying?
The observer witnessed a profound change occurring while conducting their research.
Can internal energy be equal to zero?
Yes, if the process is occurring under an isothermal condition where change in T=0
How can you determine if a chemical reaction is occurring, and what are two methods to identify this process?
You can determine if a chemical reaction is occurring by observing changes in the physical or chemical properties of the substances involved. Two methods to identify this process are observing the formation of a precipitate or a color change in the reaction mixture.
You often describle development as occurring in stages or as what?
Development is often described as occurring in stages or as a process of gradual change and growth over time. It is a dynamic and complex process that involves a series of interconnected milestones and transitions that individuals go through as they mature and learn.
When a substance gives off or absorbs heat is that a sign that describes a sign of a chemical change occurring?
Yes, if a substance gives off or absorbs heat, it could be a sign that a chemical change is occurring. This process is known as an exothermic or endothermic reaction, respectively, which are common indicators of chemical reactions.
Is evaporation of spirit on the skin a physical change?
Yes, evaporation of spirit on the skin is a physical change. It is a phase change where the liquid spirit changes into a gas without any chemical reaction occurring. The process can be reversed by condensation.
Is melting of ice a physical process or a chemical process?
Physical. The chemical makeup of the water doesn't change, and no heat is absorbed or discharged (endo/exothermic).
What type of phase change is occurring in glaciers?
The phase change occurring in glaciers is solid to solid, where water vapor or liquid water freezes into solid ice. Over time, this process of accumulation and compaction of snow forms the dense ice masses that make up glaciers.
What special name is given to a heat change at constant pressure?
A heat change at constant pressure is called enthalpy change, often denoted as ΔH. It represents the change in total heat content of a system during a process occurring at constant pressure.
