Answer:
13500 N
Explanation:
According to newtons second law of motion
mass m =1500 Kg
a = 9m/s^2
Force F = mass m × acceleration a
F = 1500×9= 13500 N
We all know, Density = Mass/ volume.
When volume increases and the mass remains the same , the density will decrease considerably.
Answer:
A) HCI( hydrochloric acid)
Explanation:
HCI is a strong acid because it has more number of hydrogen ions whereas acetic acid contains less number of hydrogen ions so its a weak acid
Answer: four hundred and 18
Explanation:
Simple math showed that only 16 words are possible from a two-letter combination, but a three-letter code produces 64 words. Operating on the principle that the simplest solution is often correct, researchers assumed a three-letter code called a codon.
Answer:
2.00 M
Explanation:
The concentration of a solution is given by
where
m is the mass of solute
V is the volume of the solution
At the beginning, the solution has:
M = 6.00 M is the concentration
V = 100 mL = 0.1 L is the volume
So the mass of solute (HCl) is
Then, the HCL is diluted into a solution with volume of
V = 300 mL = 0.3 L
Therefore, the final concentration is:
