The mass of the mercury at 25°C is 121.806 g or 121.81 g.
<u>Explanation:</u>
The volume of the mercury = 9.000 mL.
The density of the mercury at 25°C = 13.534.
The mass of the mercury =?.
density d = .
⇒mass= density×volume.
mass=13.534×9.000.
mass=121.806 g or 121.81 g.
It starts to gain more energy if you keep pushing it if not it will never get more energy and the more mass it gets the slower it will become.
Depends on the thoroughness of that particular experiment. But just in general no, you usually need more than one experiment to verify a hypothesis.
Answer:
The section of the bar is 2.92 inches.
Explanation:
Mass of the steel cut ,m = 1.00 kg = 1000 g
Volume of the steel bar = V = Area × height
Height of the of the section of bar = h
Area of Equilateral triangular =
a = 2.50 inches
Cross sectional area of the steel mass = A
Density of the steel = d =
h = 2.92 inches
The section of the bar is 2.92 inches.
