Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
Answer:
A taiga biome is different from a tundra biome because it has trees.
Explanation:
The taiga has a thick forest of conifers such as pine and spruce, while in the tundra trees are absent completely.
The correct answer is D. Plants growth increases in the spring.
This is because observations must be objective, meaning that all people would state the same idea. This is not true for options like A and B, which are popular opinions, but definitely could be argued opinionatedly rather than with evidence that could support option D.
Hope this helps!
