Calculate the displacement (the total volume of the cylinder through which the piston move) of a 5.70L automobile engine in cubi

Novay_Z [31]

Answer:

348 inches³

Explanation:

From our previous knowledge of units conversion:

We know that 1000 cm³ makes 1 Liter.

Thus, for a 5.70 L automobile engine in cubic meters will be:

= 5.70 × 1000 cm³

= 5700 cm³

Now, the displacement of the automobile in cubic inches provided that 1 inch = 2.534 cm is:

⇒ 5700× (1/ (2.54)³) in³

= 5700×0.0610 in³

= 347.7 in³

≅ 348 inches³

why are the theoretical density values of brass, bronze, and steel reported as a range of densities? how can you categorize thes

Julli [10]

Answer:

Theoretical density values

brass- $8.4-8.73 gm/cm^3$

bronze- $8.73 g/cm^3$

steel- $7.75 - 8.05 gm/cm^3$

Explanation:

All of these substances are alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.
