What is the typical composition of solder? The most popular combination is 60% tin, 39% lead, and 1% alloys. This combination is strong, has a low melting range, and melts and sets quickly. A higher tin composition gives the solder higher corrosion resistances, but raises the melting point. What is the composition of lead-free solder? […]
Is a joule equal to one newton meter?
What are the four types of crystals?
What are the four types of crystals? Crystalline substances can be described by the types of particles in them and the types of chemical bonding that takes place between the particles. There are four types of crystals: (1) ionic , (2)metallic , (3) covalent network, and (4) molecular . What is the strongest attractive force […]
How are the pneumatic system and the hydraulic system similar?
How are the pneumatic system and the hydraulic system similar? Pneumatic and hydraulic systems have many similarities. Both pneumatics and hydraulics are applications of fluid power. They each use a pump as an actuator, are controlled by valves, and use fluids to transmit mechanical energy. What is hydrostatic transmission system? The hydrostatic transmission transmits energy […]
How are the 32 bits of an IP address organized in a typical large network?
What are the two basic categories of cutting tools in machining?
What are the two basic categories of cutting tools in machining? The two categories are (1) single-point tools, used in operations such as turning and boring; and (2) multiple-edge cutting tools, used in operations such as milling and drilling. What is abrasive machining process? Abrasive machining is a machining process where material is removed from […]
How does an inductor increase voltage?
How does an inductor increase voltage? Similarly, if the current through the inductor decreases, the magnetic field strength decreases, and the energy in the magnetic field decreases. This energy is returned to the circuit in the form of an increase in the electrical potential energy of the moving charges, causing a voltage rise across the […]
Does solar power work with artificial light?
Does solar power work with artificial light? Solar cells generally work well with natural sunlight, as most uses for solar-powered devices are outdoors or in space. Because artificial sources of light such as incandescent and fluorescent bulbs mimic the Sun’s spectrum, solar cells can also work indoors, powering small devices such as calculators and watches. […]
Which is a work producing device?
Which is a work producing device? Flow devices containing moving components for work out: Turbine. Produces mechanical work from an incoming high-pressure stream. Often approximated as adiabatic. Term often used for turbines with nontrivial heat transfer. Why is the work greater for a reversible process than for an actual process? The reason why more work […]
What is the US customary unit for temperature?
What is the US customary unit for temperature? The U.S. customary measurement unit for temperature is °Fahrenheit. Customary system is called the International System of Units or the Modern Metric System. Which unit of measurement is used in the US customary system? In math, the customary system can be defined as a set of weights […]
