Answer:
1. Increase Efficiency: Insulating the condensate or hot water return lines reduces heat loss from the water returning to the boiler. The hotter the water returning to the boiler is, the quicker it is to convert back to steam, which takes less energy to accomplish.
Explanation:
Answer:
Exploratory
Explanation:
<u>Focus groups</u>
It is a small group of 8-12 respondents guided by a moderator through a thorough debate on a specific subject or idea.It's great for generation of ideas, brainstorming, insight into motives, attitudes, and perceptions. it can show likes, dislikes,emotional requirements and prejudices.
Exploratory methods are used to gain initial insights that could pave the way for further investigation.
Some of the exploratory methods are focus groups, Key informant,case studies,secondary data and observational data.
Energy of gamma rays is given by equation
![E = h\nu](https://tex.z-dn.net/?f=E%20%3D%20h%5Cnu)
here we know that
h = Planck's constant
![\nu = frequency](https://tex.z-dn.net/?f=%5Cnu%20%3D%20frequency)
now energy is given as
![E = 4.70 MeV = 4.70 \times 10^6 \times 1.6 \times 10^{-19}](https://tex.z-dn.net/?f=E%20%3D%204.70%20MeV%20%3D%204.70%20%5Ctimes%2010%5E6%20%5Ctimes%201.6%20%5Ctimes%2010%5E%7B-19%7D)
![E = 7.52 \times 10^{-13} J](https://tex.z-dn.net/?f=E%20%3D%207.52%20%5Ctimes%2010%5E%7B-13%7D%20J)
now by above equation
![E = h\nu](https://tex.z-dn.net/?f=E%20%3D%20h%5Cnu)
![7.52 \times 10^{-13} = 6.6 \times 10^{-34} \nu](https://tex.z-dn.net/?f=7.52%20%5Ctimes%2010%5E%7B-13%7D%20%3D%206.6%20%5Ctimes%2010%5E%7B-34%7D%20%5Cnu)
![\nu = 1.14 \times 10^{21} Hz](https://tex.z-dn.net/?f=%5Cnu%20%3D%201.14%20%5Ctimes%2010%5E%7B21%7D%20Hz)
now for wavelength we can say
![\lambda = \frac{c}{\nu}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7Bc%7D%7B%5Cnu%7D)
![\lambda = \frac{3\times 10^8}{1.14 \times 10^{21}}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B3%5Ctimes%2010%5E8%7D%7B1.14%20%5Ctimes%2010%5E%7B21%7D%7D)
![\lambda = 2.63 \times 10^{-13} m](https://tex.z-dn.net/?f=%5Clambda%20%3D%202.63%20%5Ctimes%2010%5E%7B-13%7D%20m)

Since everything in the circuit is in series .. .
-- The total resistance is (3 + 2) = 5 ohms.
-- The voltage across the 3-ohm resistor is 3/5 of the total voltage.
-- The voltage across the 2-ohm resistor is 2/5 of the total voltage.
(2/5) of (9 volts) = 18/5 = 3.6 volts .
