Are silent run on power and have to be electricly charged
The amount of heat transferred to water is equal to the amount of heat that is lost by the piece of iron dropped to it. To solve for the quantity of the heat in either direction, we use the equation,
H = mcpdT
where H is heat, m is mass, cp is the specific gravity, and dT is the change in temperature. Substituting,
H = (200g)(0.444 J/g°C)(100°C - 22°C)
H = 6926.4 J
Thus, the heat lost by the piece of iron is approximately 6926.4 J.
That transition produces one of the lines in the "Lyman series". A photon is emitted with a wavelength of 102.57 nm, in the ultraviolet.

Answer:
The gram is the basic unit of measurement
Explanation:
You use it to weigh small items such as sugar, flour, coffee, and other items that are similar.
If you want to measure in grams using a scale is the most accurate solution.
