Answer:
That means they should actually pay attention.
Explanation:
Yes or no because I don't know and im tired
You said 0.5 · m · v² = m · g · h
Divide each side by 'm' : 0.5 · v² = g · h
Multiply each side by 2 : v² = 2 · g · h
Square root each side : v = √(2 · g · h)
You said that g = 9.8 m/s² and h = 875 units
So v = √(9.8 m/s² · 875 units)
v = √(8,575 m·unit/s²)
v = 92.6 / s² · √(m · unit)
Answer:
1.5g/cm³
Explanation:
Given parameters:
Initial volume of the liquid = 30cm³
Final volume of the liquid = 50cm³
Mass of the liquid = 30g
Unknown:
Density of the liquid = ?
Solution:
Density is the mass per unit volume of a substance.
Density =
volume of the liquid = final volume - initial volume = 50cm³ - 30cm³
volume of the liquid = 20cm³
Density =
= 1.5g/cm³
