The answer is A) Cl
All the other are noble gases therefore rarely, if ever, form ions
Answer:
<u>Constructive interference defination:</u>
''Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes''
Constructive interference occurs at integer multiples of the wavelength of the wave. The lowest incidence occurs at the wavelength.
<em>As we know,</em>
wavelength * frequency = velocity
wavelength = v/f
= (343 m/s) / (220 1/s)
= 1.56 m
Answer:
n physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is {\displaystyle {\begin{smallmatrix}{\frac {1}{2}}mv^{2}\end{smallmatrix}}}{\begin{smallmatrix}{\frac {1}{2}}mv^{2}\end{smallmatrix}}. In relativistic mechanics, this is a good approximation only when v is much less than the speed of light.
The standard unit of kinetic energy is the joule, while the imperial unit of kinetic energy is the foot-pound.
Explanation:
Sliding friction is harder to overcome, and steals
more energy whenever you're moving.
That's why we switched from sleds to wheels
several thousand years ago.
