Which of these statements are correct? A ball with a velocity of 10 m/s at an angle of 30 degrees with the horizontal has a vertical velocity of 5 m/s.

A ball thrown up at 10m/s from a height of 5 m will strike the ground 1 second later.

A ball thrown up at 10m/s from a height of 15 m will strike the ground 3 seconds later.

A ball with a velocity of 10 m/s at an angle of 30 degrees with the horizontal has a horizontal velocity of 5 m/s.

The vertical component of a vector is found by multiplying the total vector by the cosine of the angle.

A boy walks 9 m west and then 12 meters north, the magnitude of the displacement is 15m.

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
