8 kilometer? is that right or explain to me pls.
Answer:
Average density of the liquid = 0.992 g/mL
Explanation:
Density = mass/volume
mass of liquid = (mass of liquid + mass of cylinder) - mass of cylinder
Trial 1: mass of liquid = 19.731 - 9.861 = 9.87
volume of liquid = 10 mL
density of liquid = 9.87 g / 10 mL = 0.987 g/mL
Trial 2: mass of liquid = 19.831 - 9.861 = 9.97
volume of liquid = 10 mL
density of liquid = 9.97 g / 10 mL = 0.997 g/mL
Trial 3: mass of liquid = 19.831 - 9.861 = 9.97
volume of liquid = 10 mL
density of liquid = 9.97 g / 10 mL = 0.997 g/mL
Trial 4: mass of liquid = 19.771 - 9.861 = 9.91
volume of liquid = 10 mL
density of liquid = 9.91 g / 10 mL = 0.991 g/mL
Trial 5: mass of liquid = 19.751 - 9.861 = 9.89
volume of liquid = 10 mL
density of liquid = 9.89 g / 10 mL = 0.989 g/mL
Average density = (0.987 + 0.997 + 0.997 + 0.991 + 0.989)/5 = 4.961/5
Average density of the liquid = 0.992 g/mL
Answer:
[H⁺] = 
×
M
Explanation:
pH= - log[H⁺]
=> 3.2 = - log[H⁺]
=> [H⁺] = 
∴ [H⁺] = × M
pls mark it as brainliest
The function is known as the atomic orbital.
The electron is most likely to be found at a distance from the nucleus equal to the Bohr radius.
For Hydrogen,...
an electron in the ground state has the energy of -13.6eV.
This is relative to the ionization threshold.
Hoped this helped ;)<span />
Answer:
The heat flows from iron block to lead block then it flows from lead block to iron block until the temperature of three blocks are equal.
Explanation:
Given data
Temperature of the copper block = 20 °c
Temperature of the lead block = 30 °c
Temperature of the iron block = 70 °c
We know that according to law of thermodynamics heat always flows from higher temperature body to lower temperature body Until the temperature of all bodies becomes equal.
Therefore in the given problem the heat flows from iron block to lead block then it flows from lead block to iron block until the temperature of three blocks are equal.
