Answer:
T2 = 355.92 Kelvin or 82.92°C
Explanation:
Given the following data;
Mass = 567g to kilograms = 567/1000 = 0.567 kg
Quantity of heat = 18,100J
Initial temperature = 15°C to Kelvin = 15 + 273 = 288K
Specific heat capacity of iron = 470j/kg•k
To find the final temperature;
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
Making dt the subject of formula, we have;
Substituting into the equation, we have;
dt = 67.92K
Now, the final temperature T2 is;
But, dt = T2 - T1
T2 = dt + T1
T2 = 67.92 + 288
T2 = 355.92 Kelvin or 82.92°C
Answer:
275 MPa, -175 MPa
-0.63636
450 MPa
Explanation:
= Maximum stress
= Minimum stress
= Mean stress = 50 MPa
= Stress amplitude = 225 MPa
Mean stress is given by
Stress amplitude is given by
Maximum stress level is 275 MPa
Minimum stress level is -175 MPa
Stress ratio is given by
The stress ratio is -0.63636
Stress range is given by
Magnitude of the stress range is 450 MPa
<span>When reading a buret, the initial reading should be taken from the top of the glassware and the final volume should still taken at the top. If the buret is completely, the initial volume for most buret would be zero. though, there are some where their initial starts at 50 decreasing to zero.</span>
