What is the importance of conversation? Conversations are key to language development, the exchange of thoughts and ideas and listening to each other. People learn by hearing each other’s thoughts while observing facial and body expressions that show emotions. How do you learn conversation? Here are five key things that will put us on the […]
How do you calculate the concentration of dissolved oxygen in water?
How do you calculate the concentration of dissolved oxygen in water? a) If we suppose that ppm are cm^3/m^3, we can calculate oxygen concentration as: V(O2)/V(total) = (209.5+x)cm^3/10^-3m^3. b) If ppm = mg/l: m(O2)/V(total) = (209.5+x)*32/(Vm*1). What is the concentration of dissolved oxygen in water? The oxygen content of surface waters of normal salinity in […]
What is the de Broglie wavelength of an electron accelerated by a voltage of 50v?
What do you think the penalty should be for a DUI?
What do you think the penalty should be for a DUI? A first DUI carries $390 to $1,000 in fines plus a number of “penalty assessments” that can substantially increase the amount the driver has to pay. The total can be several thousand dollars or more. Jail. It’s possible for a first offender to receive […]
What is the position of the particle when it is farthest to the right?
What is the position of the particle when it is farthest to the right? The absolute maximum of s(t) on a closed interval represents the farthest right the particle travels to on the interval. The absolute minimum of s(t) on a closed interval represents the farthest left the particle travels to on the interval. How […]
How do you calculate the deflection of a simply supported beam?
How do you calculate the deflection of a simply supported beam? Generally, deflection can be calculated by taking the double integral of the Bending Moment Equation, M(x) divided by EI (Young’s Modulus x Moment of Inertia). What is the deflection of a simply supported beam? Typically, the maximum deflection is limited to the beam’s span […]
What is a task involved in the design and pre-construction pathway?
What is a task involved in the design and pre-construction pathway? Which of the following is a task involved in the Design and Pre-Construction pathway? Renovating structures. Ensuring structures meet government codes. Determining the layout of the land. Planning preventative maintenance. Which of the following occupations is part of the design pre-construction career pathway? Architecture […]
What is the difference between thermal equilibrium and thermodynamic equilibrium?
What is the difference between thermal equilibrium and thermodynamic equilibrium? A thermal equilibrium exists within a system when the temperature is uniform throughout so that there is no heat transfer within the system. A system is said to be in thermodynamic equilibrium if it does not have the capacity to spontaneously change its state after […]
What is the difference between brittle fracture and ductile fracture?
What is the difference between brittle fracture and ductile fracture? Brittle fracture means fracture of material without plastic deformation or with very small plastic deformation before fracture. Ductile fracture means fracture of material with large plastic deformation before fracture. How do ductile and brittle materials differ in their behavior in the compression test? DUCTILE MATERIAL […]
What is assembly language and machine language?
What is assembly language and machine language? Difference Between Assembly Language and Machine Language. Machine language is a language that has a binary form. It can be directly executed by a computer. While an assembly language is a low-level programming language that requires software called an assembler to convert it into machine code. Which language […]
