The meter per second is the SI unit of speed. It expresses the distance traveled in a given time. One meter per second is equal to the speed of light in a vacuum. How do you write meters per second? The SI unit for velocity is the meter per second (m/s). To write meters per … Read more
A meter is a unit of measure used to quantify the amount of something, such as electrical current, length, or volume. The International System of Units (SI) defines the meter as the distance traveled by light in a vacuum in 1/299,792,458 of a second. In other words, the meter is the distance light travels in … Read more

Wien’s constant is the value of the constant in Wien’s displacement law, which states that the wavelength λ of the peak of the black-body radiation curve is inversely proportional to the temperature T of the black body: λ_{max} = frac{b}{T} where b is Wien’s constant, equal to 2.8977729(17)×10−3 m·K. The law is named after Wilhelm … Read more
In computer science, a liquid is a data structure that can be resized without having to re-allocate or copy its contents. A liquid is similar to an array, except that the size of a liquid can be changed dynamically. This makes liquids well-suited for applications where the amount of data is not known in advance, … Read more
