Answer:
<em>The rise in temperature will be less than 5 °C in the second minute.</em>
Explanation:
According to heat conduction law, the rate of heating is proportional to the temperature difference or temperature gradient. The temperature gradient is what drives heat to move from a hotter body at a higher temperature gradient to a colder body at a lower temperature gradient. For the potato, the initial first minute raises the temperature to 5 °C, consequently reducing the temperature gradient between the potato and the heating element in the oven. <em>This reduced temperature gradient means that the rate at which it will conduct heat in the second minute will be lesser than that at the first minute</em>. This will continue till the potato and the heating element are at the same temperature, at which no temperature gradient will exist between them; stopping heat transfer between them.

Answer:
Explanation:
The model for the turbine is given by the First Law of Thermodynamics:
The turbine power output is:
The volumetric flow is:
The specific volume of steam at inlet is:
State 1 (Superheated Steam)
The mass flow is:
Specific enthalpies at inlet and outlet are, respectively:
State 1 (Superheated Steam)
State 2 (Saturated Vapor)
The turbine power output is:
Answer: New wheels should be re-torqued after the first 50 to 100 driving miles. This should be done in case the clamping loads have changed following the initial installation due to the metal compression/elongation or thermal stresses affecting the wheels as they are breaking in, as well as to verify the accuracy of the original installation.
Answer:
80grit
Explanation:
80 grit is coarsest grit that may be used on aluminum
The lowest grit sizes range from 40 to 60. From the given options 80 grit is practically available grit.
What is a sandpaper used for?
They are essentially used for surface preparation. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).
