Answer:
Electronegativity
Explanation:
Element: <em>An element is a substance which can not be split into simpler units by an ordinary chemical process</em>
Electronegativity: This is the power of an atom in a molecule to attract electrons. The electronegativity of an element increase across the period in the periodic table and decreases down the group. The most electronegative elements are the reactive non metals.
Examples of electronnegative element include, Oxygen, Chlorine, Fluorine, Nitrogen, sulphur etc.
Answer:
The kinetic energy when the film vault landed is 12744000J.
Explanation:
The kinetic energy is defined as:
(1)
Where m is the mass and v is the velocity.
By means of equation 1, the kinetic energy of the film vault when it landed can be determined
But ![1 J = kg.m^{2}/s^{2}](https://tex.z-dn.net/?f=1%20J%20%3D%20kg.m%5E%7B2%7D%2Fs%5E%7B2%7D)
![k_{e} = 12744000J](https://tex.z-dn.net/?f=k_%7Be%7D%20%3D%2012744000J)
Hence, the kinetic energy when the film vault landed is 12744000J.
Speed is the magnitude of velocity.
Velocity depends on both magnitude as well as direction.
Since speed is constant, direction of the object must be changed to make velocity not constant or to make velocity variable.
Hope this helps, have a great day ahead!
The amount of fluid that moves past a point in area A per unit of time is known as the flow rate.
<h3>How do you find average velocity from flow rate?</h3>
- The amount of fluid that moves past a point in area A per unit of time is known as the flow rate. Here, a uniform pipe carrying the shaded fluid cylinder passes point P in time t. The cylinder's capacity is Ad, its average velocity is v=d/t, and its flow rate is Q=Ad/t=Av.
- The average fluid velocity for laminar flow through a pipe is equal to half of the fluid's greatest velocity at the pipe's center. The Hagen-Poiseuille equation is shown above. Since there is no acceleration in a steady and uniform flow, there is no force acting in the direction of the flow.
