Acceleration (change of movement) of an object is dependent on the net force acting on it and its mass.
The relationship between acceleration (a), force (f) and mass (m) is given by the Second Lay of Newton: f = m * a.
Note that the force, f, is the net force acting on the objetct.
I hope this help you.
Answer: temperature and precipitation are the 2 most important factors that affect climate
Because it has a smaller atomic number. Elements are not lined up according to the higher average atomic mass, but rather according to the higher atomic number.
Answer: 1.2044 × 10^24
Explanation:
1 mole of calcium is 40 gram
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms, also 1 mole of calcium is 40gram
So, 1 mole of calcium = 6.02 x 10^23 atoms
Also, 1 mole of calcium is 40gram
40 grams of calcium = 6.02 x 10^23 atoms
80.156 grams of calcium = Z atoms
To get the value of Z, cross multiply:
Z atoms x 40 grams = 6.02 x 10^23 atoms x 80.156 grams
40Z = 482.54 x 10^23
Z = (482.54 x 10^23/40)
Z = 12.06 x 10^23
Put result in standard form
Z = 1.206 x 10^24 atoms
Thus, 1.206 x 10^24 atoms of Ca are present in 80.156 grams of Ca
