Answer:
Venus
Explanation:
Venus is the second plate in the solar system. It is a terrestrial planet and it is part of the inner rocky planets.
In Venus, it rains sulfuric acid but the rain never reaches the surface before it becomes evaporated. The acid forms from the combination of sulfur oxide and water in the atmosphere at a height of about 42km. As it condenses and falls, it becomes evaporated back at lower elevations. The surface is therefore protected from the sulfuric acid rain.
The sulfur oxide and water vapor must have been derived from volcanic activities in geologic times past.
This statement is false. There is actually five types of plains. The five types of plains are coastal plain, alluvial plain, glacial plain, terrestrial plain and flood plain. Plains are flat areas that are usually located in lowlands and at the bottom of the valleys.
Answer: Input Resistance (Rin) = 500 ohms , overall voltage Gain (GV) = 2 volts / volts , ID = 4/9 = 0.44 A
Explanation:
Answer: The correct answer is option(B.).
Explanation:
The co-formation theory explain that both moon and the earth are formed at same time from the primitive solar nebula (cloud made up of dust and gases) at the same and same place.
Where as capture theory suggests that the moon is an asteroid which was formed or created somewhere else in a solar system. And when the moon approached the earth planet it got captured by the earth's gravitational field.
Impact theory explains the formation of moon by the catastrophic collision between the earth and any planet half the size of earth's size.
Synchronous theory sheds the light on the rotation time, revolution time and sides of moon located from the surface of the earth.
Hence, the correct answer is option(B).
