<span>pm stands for picometer and picometers are units which can be used to measure really tiny distances. One picometer is equal to 10^{-12} meters. We know that one centimeter is equal to 10^{-2} m so there are 10^2 cm per meter.
We can change the distance d = 115 pm to units of centimeters.
d = (115 pm) x (10^{-12}m / pm) x (10^2 cm / m)
d = 115 x 10^{-10} cm = 1.15 x 10^{-8} cm
The distance in centimeters is 1.15 x 10^{-8} cm</span>
Answer:
They're called Jovian planets
The hydrogenated vegetable oil serves as a preservative, thus, the correct option is D. Hydrogenated vegetable oil are used by food industries to prevent fat rancidity in order to give their product a longer shelf life. Hydrogenated oils are very good preservatives because all the enzymatic activities in the oil has been neutralized during the hydrogenating process.
Answer: 4.80 * 10¹⁴s⁻¹
Explanation:
Speed = Frequency * Wavelength
So:
Frequency = Speed/ Wavelength
Speed of light = 3 * 10⁸ m/s
Frequency = (3 * 10⁸ m/s) / (6.25 x 10⁻⁷m)
= 4.80* 10¹⁴hz
= 4.80 * 10¹⁴s⁻¹
