Answer:
Explanation:Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
Distance = 25000000 miles
Time = 50 hours
Explanation:
Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits
Given that
Speed V = 500000 mph
Distance d = 25 000,000 miles
Speed = distance/ time
Time = distance/speed
Time = 25000000/500000
Time = 50 hours
It will therefore take 50 hours to get to venus at that speed.
The resultant vector is zero.
Explanation:
When you add displacement vectors using the head to tail method, you follow this procedure:
- Draw the first vector
- Draw the second vector, with its tail starting from the head of the first vector
- Draw the third vector, with its tail starting from the head of the second vector
.. and so on.
The resultant of the all vectors will be the vector connecting the tail of the 1st vector to the head of the last vector.
In this problem, the vectors make a closed polygon: this means that the head of the last vector coincides with the tail of the first vector.
Therefore, this means that the length of the resultant vector is zero.
