Salt is the solute in that situation
Directly proportional to volume, according to charles’s law
The inductive reactance of a 20.0-mh inductor at a certain frequency is 120 ω. 955hz is the frequency in hz
In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.
How frequently something occurs is what is meant by the word frequency. A person blinking their eyelids 47 times in a minute is an example of frequency. the quality or state of happening frequently.
Frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Grouped frequency distribution and Ungrouped In physics, frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Distribution are the two different types of frequency tables.

The temperature of the water and copper beaker be together is 29.6⁰C.
<h3>
What is the equilibrium temperature of both substance?</h3>
The final temperature or equilibrium temperature of the water and copper beaker is calculated by applying the principle of conservation of energy.
Heat lost by the water = Heat gained by the copper beaker
mcΔθ (water) = mcΔθ (copper)
where;
- m is mass
- c is specific heat capacity
- Δθ is change in temperature
m₁c₁(T₁ - T) = m₂c₂(T - T₂)
where;
- T₁ is the initial temperature of water
- T₂ is the initial temperature of copper beaker
- T is the equilibrium temperature
Specific heat capacity of copper, c₂ = 389 J/kgK
Specific heat capacity of water , c₁ = 4200 J/kgK
(2)(4200)(30 - T) = (1)(389)(T - 20)
252,000 - 8400T = 389T - 7780
259,780 = 8789T
T = 259,780 /8789
T = 29.6⁰C
