Is gold react with mercury? Mercury also alloys with other metals to form so called amalgams. The other metal becomes dissolved in the mercury. Mercury forms amalgams with most heavy metals including gold which is useful in the purification of gold and gold plating. It can also form an amalgam with sodium forming a powerful […]
What is the best example you can offer to explain a Folkway?
What is the best example you can offer to explain a Folkway? A common example of a folkway is the practice, in many societies, of waiting in line. This practice brings order to the process of buying things or receiving services, allowing us to more easily perform the tasks of our daily lives. Why do […]
What are the processes involved in technology?
What are the processes involved in technology? The technology life cycle has four distinct stages: research and development, ascent, maturity, and decline. The adoption of these technologies also has a life cycle with five chronological demographics: innovators, early adopters, early majority, late majority, and laggards. What jobs involve design and technology? Careers using design technology […]
What is the relationship between shear strength and tensile strength?
What is the relationship between shear strength and tensile strength? In tension testing, the ratio of maximum load to original cross-sectional area. Also known as ultimate strength (UTS). Shear strength is the load along a plane that is parallel to the direction of the force. Why is shear strength important? Shear strength is defined as […]
What is the weight of a 20 kg box?
What happens to the period of a simple pendulum if its length is doubled what happens if the suspended mass is doubled?
How do you explain internal energy?
How do you explain internal energy? The internal energy is the total amount of kinetic energy and potential energy of all the particles in the system. When energy is given to raise the temperature , particles speed up and gain kinetic energy. What is internal energy equation? The first law of thermodynamics states that the […]
What are the types of receptors found in humans?
What are the types of receptors found in humans? Receptors of the skin are classified as thermoreceptors, mechanoreceptors, and nociceptors—the last being sensitive to stimulation that is noxious, or likely to damage the tissues of the body. Thermoreceptors are of two types, warmth and cold. What are examples of general senses? The general senses are […]
How do you calculate effort in person hours?
What is the formula for position?
What is the formula for position? A common application of derivatives is the relationship between speed, velocity and acceleration. In these problems, you’re usually given a position equation in the form “ x=” or “ s ( t ) = s(t)= s(t)=”, which tells you the object’s distance from some reference point. What is final […]
