Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Refer to the diagram shown below.
The angle is in quadrant 4, therefore cos θ is positive.
The length of the hypotenuse is determined from the Pythagorean theorem as
c² = 3² + 4² = 25
c = 5
Calculate cosine of the reference angle.
cos θ = 3/5
Answer: 3/5
Answer:
Here not any option is matching but only (A) option is near to our answer.
The frictional force is 126.046 N
Explanation:
Given:
Mass of bullet kg
Thickness of sand bag m
Initial bullet velocity
Final bullet velocity
According to the work energy theorem,
Work done by friction force is equal to change in kinetic energy.
Here we have to find friction force
N
Here not any option is matching but only (A) option is near to our answer.
Therefore, the frictional force is 126.046 N
