Assuming brown hair (B) color is completely dominant over blond hair (b), then the father's genotype must be bb.
When object density is lesser than liquid density, it floats....BUT when it's density is greater than the liquid density, then it sinks...
The distance between the orbits of two satellites is 7.97 m.
Explanation:
Johannes Kepler was the first to propose three laws for the planetary motion. According to him, the orbits in which planets are rotating are elliptical in nature and Sun is at the focus of the ellipse. Also the area of sweeping is same.
So based on these three assumptions, Kepler postulated three laws. One among them is Kepler's third law of planetary motion. According to the third law, the square of the time taken by a planet to cover a specified region is directly proportional to the cube of the major elliptical axis or the radius of the ellipse.
So,
Thus, for the geosynchornous satellite, as the time taken is 24 hours, then the radius or the major axis of this satellite is
Similarly, for the another satellite orbiting in time period of 12 hours, the major axis of this satellite is
So, the difference between the two radius will give the distance between the two orbits, 13.21-5.24 = 7.97 m.
So the distance between the orbits of two satellites is 7.97 m.
The half-life observed by an observer at rest is 1.25 s
Explanation:
In this problem, the particle is travelling at a significant fraction of the speed of light: therefore, we have to consider the phenomenon of the time dilation. The half-life of the particle as measured by an observer at rest is given by
where
is the proper half-life of the particle
v is the speed of the particle
c is the speed of light
For the particle in this problem,
Substituting into the equation, we find:

1. Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. The science of fermentation is known as zymology.
2. In general, the longer that fermentation goes on, the more sugar is converted into alcohol, resulting in a less sweet (or “drier”) and more alcoholic beverage. To produce beer, various grains are used instead of grapes as the source of sugars. ... This drying process converts the starches present in grain into sugars
