Answer:
Explanation:
a)
Apply the law of conservation of momentum
Since there is no external force(friction) oon the system, Momentum in horizontal direction must remain constant.
Initial Momentum = Final Momentum
b)
Apply law of conservation of energy
Loss in Potential Energy = Gain in Kinetic Energy
A recessive genotype needs to be homozygous (Both alleles the same) for the phenotype to show. The common school example of course being Eye colour of Blue or Brown. If someone is a carrier, then that means they have the allele needed for the condition, but they don't show it because they are heterozygous for it, so the dominant allele shows instead. Because only person carries the recessive allele, when they reproduce, there will be no recessive allele in the second person to connect with the recessive allele in the first person, so at best the offspring can only be a carrier too.
Answer:
The best answer is "B"
Both Technician A and B
Explanation:
The master cylinder is a hydraulic pump. As you pump the pedal, it forces the brake fluid into the calipers/wheel cylinders. However, air compresses quite easily, as such the hydraulic pressure reduce the by large amounts because of the presence of air in the braking system.
The two Technicians are both right.
Answer:
The resistance of the axon is .
Explanation:
Given that,
Inner diameter of the model of an axon,
Radius of the model,
Resistivity of the fluid inside the tube wall,
Length of the axon, l = 2 mm = 0.002 m
We know that the resistance in terms of resistivity of an object is given by :
So, the resistance of the axon is . Hence, this is the required solution.
