The answer for you is chemical properties
Answer:
The nucleus contains protons, which have a positive charge
Explanation:
The rate of change of B is double that of A so:
rate of change of B = -2 x 0.19
rate of change of B = -0.38 M/s
Answer:
through natural selection
Explanation:
Natural selection is the driving mechanism of the evolution of species. Organisms can survive more in an environment if they are capable to adapt the changing environmental conditions. After surviving they are also able to pass their modified trait into their future generations (evolution).
Helpful variations accumulate through natural selection, as the organisms that are better adapted to their environment reproduce offspring with the same variations.
Pressure is the force exerted on an object per unit area. The equation is expressed as:
P = F / A
From the given above, we substitute the values to the equation.
P = F/A
P= F / (12.56r²)
P = 45 N / (12.56 x 5²
P = 0.143 N/m²
Therefore, the correct answer is option C, <span>1.4 x 10^-1 Pa.</span>
