Answer:
9500 kJ; 9000 Btu
Explanation:
Data:
m = 100 lb
T₁ = 25 °C
T₂ = 75 °C
Calculations:
1. Energy in kilojoules
ΔT = 75 °C - 25 °C = 50 °C = 50 K
![m = \text{100 lb} \times \dfrac{\text{1 kg}}{\text{2.205 lb}} \times \dfrac{\text{1000 g}}{\text{1 kg}}= 4.54 \times 10^{4}\text{ g}\\\\\begin{array}{rcl}q & = & mC_{\text{p}}\Delta T\\& = & 4.54 \times 10^{4}\text{ g} \times 4.18 \text{ J$\cdot$K$^{-1}$g$^{-1}$} \times 50 \text{ K}\\ & = & 9.5 \times 10^{6}\text{ J}\\ & = & \textbf{9500 kJ}\\\end{array}](https://tex.z-dn.net/?f=m%20%3D%20%5Ctext%7B100%20lb%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20kg%7D%7D%7B%5Ctext%7B2.205%20lb%7D%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1000%20g%7D%7D%7B%5Ctext%7B1%20kg%7D%7D%3D%204.54%20%5Ctimes%2010%5E%7B4%7D%5Ctext%7B%20g%7D%5C%5C%5C%5C%5Cbegin%7Barray%7D%7Brcl%7Dq%20%26%20%3D%20%26%20mC_%7B%5Ctext%7Bp%7D%7D%5CDelta%20T%5C%5C%26%20%3D%20%26%204.54%20%5Ctimes%2010%5E%7B4%7D%5Ctext%7B%20g%7D%20%5Ctimes%204.18%20%5Ctext%7B%20J%24%5Ccdot%24K%24%5E%7B-1%7D%24g%24%5E%7B-1%7D%24%7D%20%5Ctimes%2050%20%5Ctext%7B%20K%7D%5C%5C%20%26%20%3D%20%26%209.5%20%5Ctimes%2010%5E%7B6%7D%5Ctext%7B%20J%7D%5C%5C%20%26%20%3D%20%26%20%5Ctextbf%7B9500%20kJ%7D%5C%5C%5Cend%7Barray%7D)
2. Energy in British thermal units

Answer:
Out of the four options provided
option A. actuator
is correct
Explanation:
An actuator is the only device out of the four mentioned devices that provides power and ensures the motion in it in order to manipulate the movement of the moving parts of the damper or a valve used whereas others like ratio regulator are used to regulate air or gas ratio and none mof the 3 remaining options serves the purpose
Answer:
Using the above algorithm matches one pair of Ghostbuster and Ghost. On each side of the line formed by the pairing, the number of Ghostbusters and Ghosts are the same, so use the algorithm recursively on each side of the line to find pairings. The worst case is when, after each iteration, one side of the line contains no Ghostbusters or Ghosts. Then, we need n/2 total iterations to find pairings, giving us an P(
)- time algorithm.
I would love to answer but unfortunately there is no picture.
