This is called an organ. Examples of organs are: your heart, brain, lungs, liver, stomach etc.
Answer:
Explanation:
The energy emitted by a single photon is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
For the photons emitted by the zinc atoms,
So the energy of a single photon emitted is
And since the number of atoms is
The total energy emitted will be
Blu ! The formula is right THERE, IN the question. All you have to do is plug numbers into it.
The formula: Kinetic Energy = 1/2 m v²
' m ' is 2,000 kg
' v ' is 22 m/s
Now pluggum in:
KE = (1/2) (2,000 kg) (22 m/s)²
KE = (1/2) (2,000 kg) (22 m/s x 22 m/s)
KE = (1/2) (2,000 kg) (484 m²/s²)
I'm <u><em>sure</em></u> you can finish it off from this point, and pick the correct choice.
Answer:
Solute
Explanation:
a solute is dissolved into a solvent to make a solution
Answer:
8400m
Explanation:
The engine that falls off would have the same constant horizontal velocity as the airplane's when if falls off if we ignore air resistance. So it would have a horizontal velocity of 280m/s for 30seconds before it hits the ground.
Therefor the horizontal distance the engine travels during its fall is
280 * 30 = 8400m
