Okay whats the question though?
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

Answer:
- Problem-recognition.
Explanation:
The consumer decision-making process is associated with the process of consumers recognizing their needs and requirements, collecting information followed by the evaluation of distinct alternatives available in the market and then finally reaching a decision to opt for a specific product to buy.
As per the given description, Gilbert's evaluation of his need that his current phone is not able to meet up his requirement and realization that he requires a phone with a longer-battery life exemplifies that he is in the '<u>problem-recognition</u>' phase of the consumer decision-making process. This stage would be followed by the assessment of alternatives(various phones with longer battery life) and reaching the conclusion to buy a specific chosen product after the evaluation.
Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
