A thin spherical shell with radius R1 = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm . Both
kakasveta [241]

Answer:

The right response will be "450 volts".

Explanation:

The given values are:

R1 = 4.00 cm

R2 = 6.00 cm

q1 = +6.00 nC

q2 = −9.00 nC

As we know,

The potential difference between the two shell's difference will be:

⇒  \Delta V=K[(\frac{q1}{R1}+\frac{q2}{R2})-(\frac{q1}{R1} +(\frac{q2}{R2}))]

           =K[\frac{q1}{R2}-\frac{q1}{R1} ]

On substituting the values, we get

           =(9\times 10^9)[\frac{6\times 10^{-9}}{0.04}-\frac{6\times 10^{-9}}{0.06}]  

       Δ =450 \ volts

Ty has two pet mice. One mouse has the gene for black fur color and the other mouse has the gene for white fur color. The female
Alex Ar [27]

Answer:

Ty has two pet mice. One mouse has the gene for black fur color and the other mouse has the gene for white fur color. The female mouse is pregnant now, and Ty wonders what color or colors the baby mice will be. Read each offspring description phrase below and select the correct pattern of dominance for each.

___ all white fur offspring, white fur in this case is dominant

___ all gray fur offspring, this is incomplete dominant.

___ all black fur offspring, this is black fur dominantice

___ all black and white offspring, this is codominance .

Explanation:

Incomplete dominance: Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance.

Codominance: Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
