False it’s the unit of force
The Kelvin scale has no negatives on it.
Zero Kelvin is 'Absolute Zero', and nothing can get colder than that.
The acceleration is 3 m/s per minute, or 0.05 m/s per second.
Answer:
D. a cation that has a smaller radius than the atom.
Explanation:
When electrons are removed from the outermost shell of a calcium atom, the atom becomes a cation that has a smaller radius than the atom.
<span>Since frequency and wavelength have inverse relationship. It can be expressed by the equation:
ν.λ = c
Where,
v = frequency of the electromagnetic wave.
λ = it's wavelength
c = the speed of light in a vacuum.
v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz
that means that in one second it covers 2.00 x 10^9 cycles.
λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers</span>
