Can gravity be seen? Gravitational effects are only way we can detect its presence. Although dark matter does not scatter light, its gravitational pull can still bend the path of light. This effect, called gravitational lensing, can cause distorted or multiple images of the same object to appear. Does time not exist? Neither the metrics […]
Why is resistance necessary in a circuit?
Why is resistance necessary in a circuit? In an electronic circuit, the basic function of a resistor is to limit the current to a safe value so that the associated sophisticated parts can function properly. Here R is the constant of proportionality and is known as the resistance of the resistor. How do you control […]
Which of the following is true based off your observation of intrusive igneous rocks?
Which of the following is true based off your observation of intrusive igneous rocks? Which of the following is true based off your observation of intrusive igneous rocks on Earth’s surface? -Intrusive igneous rocks were formed from volcanic eruptions. -These rocks were formed from a lava flow that eventually cooled and solidified. -Intrusive igneous rocks […]
What is mass production process?
What is mass production process? Mass production is the manufacturing of large quantities of standardized products, often using assembly lines or automation technology. In mass production, mechanization is used to achieve high volume, detailed organization of material flow, careful control of quality standards, and division of labor. What are some examples of mass production? Mass […]
What are ethical issues with gene therapy?
What are ethical issues with gene therapy? The ethical questions surrounding gene therapy include: How can “good” and “bad” uses of gene therapy be distinguished? Who decides which traits are normal and which constitute a disability or disorder? Will the high costs of gene therapy make it available only to the wealthy? What are the […]
What is flash chamber in refrigeration?
What is flash chamber in refrigeration? A flash chamber is a device which separates liquid from vapors. Only liquid is then passed to evaporator and the vapors will be passed to the compressor directly. This flash chamber between the condenser and evaporator is known as flash intercooling. What does quality mean when referring to a […]
Which material is used as vibration isolation?
Which material is used as vibration isolation? Pads or sheets of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials. Elastomer pads, dense closed cell foams and laminate materials are often used under heavy machinery, under common household items, in vehicles and even under higher performing audio systems. How do you isolate […]
What does a wind tunnel measure?
What does a wind tunnel measure? In wind engineering, wind tunnel tests are used to measure the velocity around, and forces or pressures upon structures. What does pressure coefficient mean? The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in […]
What results from the presence of an extra half plane of atoms in a crystal?
What results from the presence of an extra half plane of atoms in a crystal? Some atomic lattice distortion exists around the dislocation line because of the presence of the extra half-plane of atoms. There are regions in which compressive, tensile and shear lattice strains are imposed on the neighboring atoms. Two edge dislocations that […]
What is RC high pass filter?
What is RC high pass filter? A high pass RC filter, again, is a filter which passes through high-frequency signals, composed of a resistor and capacitor. To create a high pass RC filter, the capacitor is placed in series with the power signal entering the circuit, such as shown in the circuit below: The above […]
