Answer:
The wavelength of a wave is 1.72 m.
Explanation:
Given,
Frequency, f = 0.9 Hz
Speed of a wave, v = 154.9 cm/s = 1.549 m/s
The speed of a wave is given by :
So, the wavelength of a wave is 1.72 m. Hence, this is the required solution.
Answer:
Small, made of rocks, made of few moons.
Explanation:
The inner planets are also called the terrestrial planets and are mostly rock. These planets are Mercury, Venus, Earth and Mars.
They are made of dense balls of rocks with a few moons. They are believed to have been formed from denser rocky materials that accreted first during the early formation of the solar system.
Outside the terrestrial planets are the gas giants which are mostly made of large masses of gas. The Asteroid belt separates the inner and outer planet from each other.
All of these are necassary for photosynthesis. So your answer would be all of the above.
