Answer: Final Temperature= 40.57 deg C; Latent Heat of Fusion of Ice= 80.14 cal/g
Explanation:
The system is said to be isolated to the surroundings. All energy must remain inside the system. We can state that no loss of energy takes place, thus,
Answer:
There are two types of bone marrow – red bone marrow (myeloid tissue) and yellow bone marrow (fatty tissue). Red bone marrow is involved in production of blood cells, while yellow marrow is important for fat storage. As you age, yellow bone marrow replaces red bone marrow.

Answer:![\theta =79.47 North\ of\ west](https://tex.z-dn.net/?f=%5Ctheta%20%3D79.47%20North%5C%20of%5C%20west)
Explanation:
Given
Mass of airplane =21500 kg
Force due to jet engines=35100 N
Force from wind is 14900 N at angle of 75 south of west
Resolving forces
![F_x=14900cos75=-3856.403 N](https://tex.z-dn.net/?f=F_x%3D14900cos75%3D-3856.403%20N)
![F_y=35100-14900sin75](https://tex.z-dn.net/?f=F_y%3D35100-14900sin75)
![F_y=35100-14392.29=20707.70 N](https://tex.z-dn.net/?f=F_y%3D35100-14392.29%3D20707.70%20N)
Therefore acceleration in x direction
![a_x=\frac{F_x}{m}=\frac{-3856.403}{21500}=-0.179 m/s^2](https://tex.z-dn.net/?f=a_x%3D%5Cfrac%7BF_x%7D%7Bm%7D%3D%5Cfrac%7B-3856.403%7D%7B21500%7D%3D-0.179%20m%2Fs%5E2)
![a_y=\frac{F_y}{m}=\frac{20707.70}{21500}=0.963 m/s^2](https://tex.z-dn.net/?f=a_y%3D%5Cfrac%7BF_y%7D%7Bm%7D%3D%5Cfrac%7B20707.70%7D%7B21500%7D%3D0.963%20m%2Fs%5E2)
Direction of acceleration
![tan\theta =\frac{a_y}{a_x}=\frac{0.963}{0.179}=-5.38](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%5Cfrac%7Ba_y%7D%7Ba_x%7D%3D%5Cfrac%7B0.963%7D%7B0.179%7D%3D-5.38)
![\theta =79.47\ North\ of\ west](https://tex.z-dn.net/?f=%5Ctheta%20%3D79.47%5C%20North%5C%20of%5C%20west)
