Polymerisation is the joining together of monomers to form polymers. Monomers are the repetitive units in polymers.
My mother's age is three times my age. The sum of our ages is 40. How old am I? How old is my mom? (Hint: Let x be your age)
We start by letting x be my age. My mother will therefore be 3 * x =3x The sum of our ages is therefore; 3x + x = 40 4x=40 Divide both sides by 4 4x/4 =40/4 We therefore get; x=10 My mother is 3x, so this becomes 3 x 10 =30 Answers; I am 10 years old Mom is 30 years old
The frequency of a wave is 250 Hz and the wavelength is 0.02m.What is the speed of the wave?
To determine the speed of the wave we use the formula below; Speed=Frequency * Wavelength We then substitute the values given for frequency and wavelength.We therefore have; Speed=250*0.02 Speed=5 m/s
