Answer:
ultra-compact dwarf galaxy
Explanation:
C
Power = (work done) / (time to do the work)
Power = (2000 J) / (5 sec)
<em>Power = 400 watts</em>
Note that 1 mL (milliliter) = 1 cm^3.
The volume of water is
Vw = 50.00 mL = 50 cm^3
From tables, the density of aluminum is 2.7 g/cm^3.
Because mass = density * volume, the volume of the aluminum is
Va = (15 g)/(2.7 g/cm^23) = 5.556 m^3
Because the aluminum sinks and displaces water in the cylinder, the new volume is the sum of the volume of water and the aluminum.
New volume = Vw + Va = 50 + 5.556 = 55.556 cm^3
Answer: 55.6 cm³ (nearest tenth)
Answer:
It is very important because scientists, especially the ones with empirical experiments and results, are prone to error and the empirical data is in need to be under strict observation done not only by many scientists but also by expermiented ones. This guards everybody to change the parameters suddenly which can affect the real results of an experiment
