Answer:
The period of Earth's revolution wouldn't change at all, but certainly we would die because of the cold and lightless space.
Explanation:
A black hole is a lot of matter in a really tiny space, even you could be a black hole, but your matter has to be compressed more than a thousand million two thousand million times a grain of salt and even if that happens I can get close to you as in a normal conversation and I wouldn't fall in the black hole and all of this because your gravitational force wouldn't have change.
So the mass of the sun would remain the same, doing the same gravitational force and keeping the earth on its normal course.
Answer:
3.24 m/s
Explanation:
Suppose that the boat sails with velocity (relative to water) direction being perpendicular to water stream. Had there been no water flow, it would have ended up 0m downstream
Therefore, the river speed is the one that push the boat 662 m downstream within 539 seconds. We can use this to calculate its magnitude
So the boat velocity vector relative to the bank is the sum of of the boat velocity vector relative to the water and the water velocity vector relative to the bank. Since these 2 component vectors are perpendicular to each other, the magnitude of the total vector can be calculated using Pythagorean formula:
m/s
According to the theory of evolution, _favorable_ traits will become common in a population over time.
"Favorable," that is in a survival sense. Remember, all that matters [to the genes] is for the individual to function and survive long enough to reproduce, and thus continue those genes into a new generation, the offspring. Natural selection finds certain adaptations "favorable" if they aid in the individual's ability to survive long enough to reproduce. Evolution, on the other hand, looks at a population and how over time these favorable genes change the individuals' genetic makeup within that population.
