Mutation because they change the genes
The sentence is accurate, therefore TRUE is the answer.
Answer:
b. 9.5°C
Explanation:
= Mass of ice = 50 g
= Initial temperature of water and Aluminum = 30°C
= Latent heat of fusion = ![3.33\times 10^5\ J/kg^{\circ}C](https://tex.z-dn.net/?f=3.33%5Ctimes%2010%5E5%5C%20J%2Fkg%5E%7B%5Ccirc%7DC)
= Mass of water = 200 g
= Specific heat of water = 4186 J/kg⋅°C
= Mass of Aluminum = 80 g
= Specific heat of Aluminum = 900 J/kg⋅°C
The equation of the system's heat exchange is given by
![m_i(L_f+c_wT)+m_wc_w(T-T_i)+m_{Al}c_{Al}=0\\\Rightarrow 0.05\times (3.33\times 10^5+4186\times T)+0.2\times 4186(T-30)+0.08\times 900(T-30)=0\\\Rightarrow 1118.5T-10626=0\\\Rightarrow T=\dfrac{10626}{1118.5}\\\Rightarrow T=9.50022\ ^{\circ}C](https://tex.z-dn.net/?f=m_i%28L_f%2Bc_wT%29%2Bm_wc_w%28T-T_i%29%2Bm_%7BAl%7Dc_%7BAl%7D%3D0%5C%5C%5CRightarrow%200.05%5Ctimes%20%283.33%5Ctimes%2010%5E5%2B4186%5Ctimes%20T%29%2B0.2%5Ctimes%204186%28T-30%29%2B0.08%5Ctimes%20900%28T-30%29%3D0%5C%5C%5CRightarrow%201118.5T-10626%3D0%5C%5C%5CRightarrow%20T%3D%5Cdfrac%7B10626%7D%7B1118.5%7D%5C%5C%5CRightarrow%20T%3D9.50022%5C%20%5E%7B%5Ccirc%7DC)
The final equilibrium temperature is 9.50022°C
Answer:
Explanation: When a body covers unequal distances in equal intervals of time in a specified direction, the body is said to be moving with a variable velocity. Example: A rotating fan at a constant speed has variable velocity, because of continuous change in direction.
