Nona is one-third as old as her mother. Five years ago, she was only one fifth of the age of her mother. How old is nona now Answer: Nona is 10 years old today. Step-by-step explanation: Step 1: Assigning variable. The age of Nonas mother will be expressed in " x ". On the other hand, Nonas age will also be expressed as a fraction of x (or a fraction of her mothers age) . Always remember that it will be easier if both Nona and her mother is expressed in both variable. Step 2: Interpret the first statement "Nona is one-third as old as her mother" At present: Since the age of Nonas mother is expressed in x, then equation one and two will be Step 3: Interpret the second statement "Five years ago, she was only o ne fifth of the age of her mother" Five years ago: Age of Nonas mother= x -5 (where -5 represent "five years ago") Since Nonas age is expressed as a fraction of her mothers age, then the equation three and four will be Note: If the s...
What changes (temperature and kinetic energy) takes place in the melting process? Changes in temperature and kinetic energy take place during phase change, in this case the melting process, because a melting object takes in thermal energy from its environment. The temperature of a melting object increases , this is because the object takes in heat from the environment in an attempt to achieve equilibrium as stated in the laws of thermodynamics. Also, once an object takes in thermal energy, its kinetic energy also increases. Remember that temperature is just the measure of kinetic energy (in the atomic level, via vibration of atoms) an object has. If the temperature increases, we can say that the kinetic energy of an object (in the atomic level) increases.
