Answer:
λ = 0.0167 m = 16.7 mm
Explanation:
The wavelength of these radio waves can be found out by using the formula for the speed of radio waves:
v = fλ
where,
v = speed of radio waves = speed of light = 3 x 10⁸ m/s
f = frequency of radio waves = 18 GHz = 18 x 10⁹ Hz
λ = Wavelength = ?
Therefore,
3 x 10⁸ m/s = (18 x 10⁹ Hz)λ
λ = (3 x 10⁸ m/s)/(18 x 10⁹ Hz)
λ = 0.0167 m = 16.7 mm

Answer: mouth
Explanation:
The food digestion process in the human or animal body starts in the mouth. The mouth consists of teeth which helps in crushing and grinding of food. The mouth secretes saliva which provides lubrication to the food items.

Explanation:
The ionic compound that is used as a building material is limestone and the correct option is option 2.
Limestone is a sedimentary rock composed mainly of calcium carbonate, which is an ionic compound. It is widely used as a building material in the construction industry due to its durability, availability, and aesthetic appeal.
Its unique properties make it a suitable material for both interior and exterior use, providing strength and stability to structures. Additionally, limestone is often used as a raw material in the production of cement and concrete, further highlighting its significance in the construction field.
Thus, the ideal selection is option 2.
