Accuracy is how close you're measurement comes to an accepted or given value. I n many cases you do not know what the accepted value is, so you have nothing to compare your measurement with. The more often a measurement is taken with close precision, or reproducibility, the more likely you are to being close to your unknown accepted value.
There is a great short tutorial video covering accuracy and precision at Sciocity dot com
Answer:
hope this helps
Explanation:
organisms having a body derived from three embryonic cell layers (ectoderm, mesoderm, and endoderm), as in all multicellular animals except sponges and coelenterates.
Answer:
F. The length of day would be longer
Explanation:
- Earths rotates on its axis from the eastward to the westward direction, earth takes about 24 hours to complete its rotation. If the rate of earth's rotation on its axis slows down then the days will be longer than usual.
- Thought the length of year would remain the same. Earth rotation is also impacted by the sun and moon's gravitational pull. The disappearance of the centrifugal force form the surface would cause climate changes and seasonal extremes.
Answer:
The photon has a wavelength of
Explanation:
The speed of a wave can be defined as:
(1)
Where v is the speed,
is the frequency and
is the wavelength.
Equation 1 can be expressed in the following way for the case of an electromagnetic wave:
(2)
Where c is the speed of light.
Therefore, ![\lamba](https://tex.z-dn.net/?f=%5Clamba)
can be isolated from equation 2 to get the wavelength of the photon.
(3)
![\lambda = \frac{3.00x10^{8}m/s}{2.00x10^{14}s^{-1}}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B3.00x10%5E%7B8%7Dm%2Fs%7D%7B2.00x10%5E%7B14%7Ds%5E%7B-1%7D%7D)
Hence, the photon has a wavelength of
<em>Summary: </em>
Photons are the particles that constitutes light.
Label A: sublimation
Label B: condensation
Label C: melting
