Answer:
we must multiply the speed value by 3.6
Explanation:
To reduce a magnitude from one unit to another, it must be multiplied by the equivalence in the order necessary so that the units do not change.
To reduce speed from m / s to km / h
we write the speed and the two conversion factors
v [m / s] [1 km / 1000m] [3600 s / 1h
v 3600/1000
v 3.6
therefore we must multiply the speed value by 3.6
Answer:
c. emission of electromagnetic radiation.
Explanation:
When an atom changes its state from an excited one to the ground state, it means that the atom is changing from a state with higher energy to a state of lower energy.
This can occur, for instance, in the presence of an electronic transition (an electron moving from a higher energy level to a lower energy state) or of a nuclear transition (the nucleus get de-excited). In both cases, since the total energy must be conserved, there must be energy released. This energy is released as a photon (electromagnetic radiation), whose energy is equal to the difference between the two energy levels involved in the transition.
Answer:
False
Explanation:
it is very rare to get hyposmia
Answer:
8ft/s
Explanation:
For computing the average velocity of the cork first we have to determine the frequency which is shown below:
= 4 Hz
Now the average velocity of the cork is
= 8ft/s
We simply applied the above formulas to determine the frequency and the velocity of the cork during this motion and the same is to be considered
I'm pretty sure the answer to your question is water because water particles are very close together but don't stay the same shape
