Answer:
No
Explanation:
Heat engine is a device which operates between two thermal reservoir.One thermal reservoir supply the thermal energy to the heat engine and another thermal reservoir absorb heat rejected by heat engine.These thermal reservoir are infinite amount of heat capacity system.Temperature of thermal reservoir remain constant always.
So we can say that heat engine can not operate by using only one thermal reservoir.
Answer:
Do heavier cars really use more gasoline? Suppose a car is chosen at random. Let x be the weight of the car (in hundreds of pounds), and let y be the miles per gallon (mpg)
Explanation:
Answer:
A stainless steel containing 18wt% of Chromium are magnetic and often used for knifes and blade because of the lattice structure of the stainless steel. The stainless steel are hard, due to the molecules in chromium are smaller and which makes them look like the molecules in wrought iron.
A stainless steel which contains 18wt%Cr and 8wt%Ni are not magnetic because of the lattice structure of the metal stainless steel. This steel are not very hard, due to the molecules of larger and looks like the molecules of a cast iron.
Tool steel that are mixed with small stable carbide retains their temperature when heated above the the normal temperature that can melt steel, because the steel has been mixed with carbide. Carbide is rich in carbon, and has a very high temperature which makes it able to retain heat. When carbides mixes with metal, it boiling point increase to a very high temperature.
The teaspoon that is made up of a single piece of stainless steel that contains only Nickel is made of two parts, the handle and the bowl. The bowl part are not magnetic because it is curved and very smooth, which changes the lattice structure of that part to become FCC. The handle part are magnetic because they are plain and are not very smooth, which makes the lattice structure to be BCC.

Based on the calculations, the magnitude (a) of it's total acceleration is equal to 2.71 m/s².
<u>Given the following data:</u>
- Angle of inclination = 10°.
- Radius of curvature, r = 40 meters.
- Acceleration of the minivan, A = 1.8 m/s².
- Initial velocity, u = 0 m/s (since it's starting from rest).
<h3>How to determine the magnitude (a) of it's total acceleration?</h3>
First of all, we would determine the final velocity of the minivan by applying the first equation of motion as follows:
V = u + at
V = 0 + 1.8 × 5
V = 9 m/s.
Next, we would calculate the centripetal acceleration of this minivan:
Ac = V²/r
Ac = 9²/40
Ac = 2.025 m/s².
Now, we can determine the magnitude (a) of it's total acceleration:
a = √(Ac² + A²)
a = √(2.025² + 1.8²)
a = 2.71 m/s².
