Explanation:
The given data is as follows.
= 0.8 kg/s = 800 g, ![C_{1} = 4.18 J/g^{o}C](https://tex.z-dn.net/?f=C_%7B1%7D%20%3D%204.18%20J%2Fg%5E%7Bo%7DC)
= 1 kg = 1000 g,
= (75 - T),
= T - 25
Now, according to the law of conservation of energy,
![m_{1}C_{1}T_{1} = m_{2}C_{2}T_{2} + mL](https://tex.z-dn.net/?f=m_%7B1%7DC_%7B1%7DT_%7B1%7D%20%3D%20m_%7B2%7DC_%7B2%7DT_%7B2%7D%20%2B%20mL)
+ 30000
250.8 - 3.34T = 4.18T - 104.5 + 30
T = ![\frac{325.3}{7.52}](https://tex.z-dn.net/?f=%5Cfrac%7B325.3%7D%7B7.52%7D)
= ![43.23^{o}C](https://tex.z-dn.net/?f=43.23%5E%7Bo%7DC)
Thus, we can conclude that temperature of the warm water stream is
.
Answer:
Explanation:
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.
It would be from electrical to kinetic, so i would say a
Answer:
2m/s²
Explanation:
![acceleration = \frac{v - u}{t}](https://tex.z-dn.net/?f=acceleration%20%3D%20%20%5Cfrac%7Bv%20-%20u%7D%7Bt%7D%20)
a = (3 - 1)/1 = 2/1 = 2m/s²
There simple rules for series and parallel circuits.
For the series circuits we have the following rules:
1)The same current flows through each part of a series circuit.(<span>I = I1 = I2 = I3)
2)</span>The total resistance of a series circuit is equal to the sum of individual resistances.(<span>Req = R1 + R2 + R3)
3)The</span> voltage applied to a series circuit is equal to the sum of the individual voltage drops.(<span>V = V1 + V2 + V3)
</span>For the parallel circuits we have the following rules:
1)Voltage is the same across each component of the parallel circuit.(<span>: V = V1 = V2 = V3)
</span>2)The sum of the currents through each path is equal to the total current that flows from the source.(<span> I = I1 + I2 + I3)
3)The total resistance is equal to the sum of the reciprocal value of individual resistors in the circuit.
The x region represents the series circuit. The y region represents a combination of series and parallel circuit. This means that for y region we can apply laws for both series and parallel circuits.
So, all the equation can be applied to the y region.
However, not all equation can be applied to the x region. We can apply following equation to the x region:
1)</span><span>I = I1 = I2 = I3
</span>2)<span> V = V1 + V2 + V3
3)</span><span>Req = R1 + R2 + R3</span>
