She can buy 9 pineapples. I don't know why anyone would need that many pineapples
This is true
Because when water evaporates molecules break and separate into different atoms
Answer:
Explanation: "As a sample of matter is continually cooled, the average kinetic energy of its particles decreases. Eventually, one would expect the particles to stop moving completely. Absolute zero is the temperature at which the motion of particles theoretically ceases"
Answer:
652.174nm
Explanation:
We need to know that the speed of light never changes. It has a value of 3 × 10^8 m/s.
Given only the frequency, we can find the wavelength by dividing the value of the speed of light by the value of the frequency.
That equals = (3 × 10^8) ÷ ( 4.6 × 10^14) = 0.000000652174 m = 652.174 ÷ 10^-9m = 652.174nm
