La rapidez es una magnitud escalar que relaciona la distancia recorrida con el tiempo.
La velocidad es una magnitud vectorial que relaciona el cambio de posición (o desplazamiento) con el tiempo.
I<span>the rounded Atomic mass of iron</span>ron is
- Fe : 55.85,
Weight is equal to the mass of the object times the acceleration due to gravity (which is 9.8

on earth)
So W=mg
W=10.0 × 9.8 = 98
So the weight is 98N.
<u>Answer:</u>
<em>1. A NaCl solution with a concentration of 50g/100mL of water at 40°C:</em> The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.
<em>2. A sugar solution with a concentration of 200g/100mL of water at 40°C: </em>The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.
<em>3. A sugar solution with a concentration of 240g/100mL of water at 40°C:</em> The sugar solution with a given concentration is saturated at given temperature.
