Each elements emission spectrum is distinct because each element has a different set of electron energy levels. The emission lines correspond to the differences between various pairs of the many energy levels. The lines (photons) are emitted as electrons fall from higher energy orbitals to lower energies.
If an air traffic controller is describing the speed of an airplane as well as the direction in which it should begin its dissent, then the air traffic controller is describing the airplane's VELOCITY at that point.
20 kg*m/s because there is 2 kg mass and 10 m/s so you can multiply.
Answer:
<h2>20 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>20 m/s²</h3>
Hope this helps you
