Well, density is mass/volume. So what's 115 g / 16 cm3? That'll get you your density. Remember that density will be in g/cm3!
Answer:
Chemical formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's chemical formula cannot be reduced any more, then the empirical formula is the same as the chemical formula. Combustion analysis can determine the empirical formula of a compound, but cannot determine the chemical formula (other techniques can though). Once known, the chemical formula can be calculated from the empirical formula.
Explanation:
Answer:
Type of steels and their uses :
Type Carbon percentage uses
Low carbon steel 0.1% to 0.3 % Food cans ,car body ,nut & bolt.
Medium carbon steel 0.3% to 0.70 % Metal chains ,wheel rims,wire ropes
High carbon steel 0.7% to 1.3% Hammers,drills ,dies and taps.
High speed steel 0.6 % Cutting tools in lathe machine.
Type Properties
Low carbon steel - Fairly strong and easily get rusty
Medium carbon steel - Having high hardness than low carbon steel
High carbon steel - Having high hardness than medium carbon steel
High speed steel - Harder ,can retain its shape at high temperature
Answer:
3.76
Explanation:
We are given that
Terminal speed in the spread -eagle position,
Terminal speed in the nosedive position,
We have to find the ratio of the effective cross-sectional area A in the slower position to that in the faster position.
We know that
Area, A=
V=2.35×108m/s. That's the answer
