What is unit speed? The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used. What is unit speed formula? Speed […]
Why are color test used?
Why are color test used? Color testing is a presumptive identification technique indicating the presence or absence of a particular drug class using rapid and uncomplicated chemical methods. Owing to their relatively recent emergence, a color test for the specific identification of synthetic cathinones is not currently available. What is a microcrystalline test? Introduction. A […]
How do you present a geometric solid?
What month can a spring tide occur?
What month can a spring tide occur? Rather, the term is derived from the concept of the tide “springing forth.” Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each […]
What are the main features of periodic table?
What are the main features of periodic table? The periodic table is composed of seven horizontal rows or periods and is numbered between 1 to 7. There is a regular gradation in the properties of elements in the horizontal rows(periods) from left to right. The periodic table is composed of eight vertical columns or groups. […]
How long does it take to stop at 35 mph?
Why is the thermohaline circulation important for Earth quizlet?
Why is the thermohaline circulation important for Earth quizlet? Thermohaline Circulation transports energy throughout the ocean, playing an important role in regulating temperature. As a result of global warming, the thermohaline conveyor belt could shut down because the water is not getting cold enough to downwell. What is the concept of thermohaline circulation? The basic […]
Which of these is a property of metals?
Which of these is a property of metals? A metal can refer to an element, compound, or alloy that is a good conductor of both electricity and heat. Example metals include gold, sodium, copper, iron, and many other elements. Metals are usually malleable, ductile, and shiny. Are metals usually brittle? Are metals usually brittle? The […]
What are the 5 changes of state?
What are the 5 changes of state? Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. What is an example of a change of state? 1 Answer. Phase changes include vaporization, condensation, melting, freezing, sublimation, and deposition. Evaporation, a type of vaporization, occurs when particles of a liquid reach a high enough […]
What would increase the resistance of a metal wire?
What would increase the resistance of a metal wire? Resistance increases with the temperature of the wire. When a material gets hotter the atoms in the lattice vibrate more. What happens to resistance when temperature decreases? Thus, resistance generally increases with temperature. For small temperature changes the resistivity varies linearly with temperature: In some materials […]
