Answer:
overall density = 0.475 g/cm³
Conclusion: if will float on water
Explanation:
1) name the variables:
masa = m
volume = v
density = d
2) Formula
d = m / v ⇒ m = v × d ⇒ v = m / d
3) Solution
i) Calculate the mass of the cork
V cork = 85.0 cm³ ⇒ m = 85.0 cm³ × 0.240 g / cm³ = 20.4 g
ii) Mass of lead + cork
m = 20.0 g + 20.4 g = 40.4 g
iii) Volume of the cork and lead
Assume that, since the lead is inside the cork, the total volume is the same volume of the cork: 85.0 cm³ (any how the contribution of the lead to the volumen is so small that it does not affect the results).
iv) Calculate the overall density
d = 40.4 g / 85.0cm³ = 0.475 g/cm³
4) Conclusion:
Since the overall density is less than the density of water, the object will float.
true or false: a image created by an object located inside the focal point is virtual, enlarged, and upright
True :D
Formula is calculated by
GDP deflator =Nominal GDP/Real GDP ×(100/1)
A solution is a value or a collection of values.. when substituted for the unknowns, the equation become an equality.
Example : x + 2 = 7
When we out the 5 in place of x we get: 5 + 2 = 2
The answer is a because tjhey do move at a molecular movemn
