Answer:
Force applied on the ball when it is kicked, gravitation pull and frictional force
Explanation:
When the ball is kicked it starts accelerating, the moment when it leaves the foot acceleration starts decreasing. Here two more forces start acting on it, one is friction force caused by wind and second is tradition pull of the earth. Both these forces slow down the motion of a soccer ball and it slows down and stops.
Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
