================================================

Explanation:

Uppercase B is the brown eyed gene. It's dominant over the recessive gene lowercase b, which is for blue eyes. Convention has the uppercase letter always dominate over the lowercase recessive gene.

Note the genotypes of the offspring are all Bb. This tells us we have nothing but brown eye offspring. The visual indicator also shows four brown eyes, which backs up each Bb genotype. The phenotype is the observed brown eyes that others can see, while the genotype deals with the gene pairings.

Since four offspring out of four total have brown eyes, this means the percent of brown-eyed offspring is 4/4 = 1.00 = 100%

Answer:

How does the speaker know that the lump of metal she is holding is an asteroid?  

The patterns formed inside the metal She explains that the rock is older the earth and that it is an asteroid due to the patterns formed inside it that show it contains metallic crystals that cannot be formed on earth but in space where temperatures mean that molten metal takes billions of years to cool.  

How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.  

The speaker works with astroids she attempts to search for them for scientific use. She analyzes how long ago these rocks were coming acrost the earth. How many are in the universe.  

Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.  

Debris from the impact orbiting around the Earth shielded sunlight, halting photosynthesis.  

The impact was so extreme that life at ground zero was vaporized.  

tsunamis, landslides, earthquakes, and heat caused by the impact killed organisms near the site of impact.  

Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?  

It seems as if she does agree. I believe she has strong intentions to defend the earth and to prevent there to be any more extinction for any more animals I believe she cares to explore and recover so if she could find a way to use the asteroids to her advantage she would.

Explanation:

6. How does the speaker know that the lump of metal she is holding is an asteroid?

- The speaker knows that the lump of metal she is holding is an asteroid because the patterns formed inside the metal. She explains that the rock is older than the earth and that it is an asteroid. This is due to the patterns formed inside it. These patterns show that it contains metallic crystals that cannot be formed on earth, but instead in space where temperatures mean that molten metal takes billions of years to cool.  The scientists also use representative sampling. This is done when they deal with such large quantities of objects for estimating.

7. How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.

- The speaker “hunts” for asteroids by attempting to search for them for scientific use. She analyzes how long ago these rocks were coming across the earth and how many are in the universe.  She also is classifying them by color and shape. Some of the objects can be classified into one or more categories and this could lead to disagreements on where they should or should not be listed. Also, the objects can be difficult to see properly.

8. Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.

- The asteroid hit at high velocity and effectively vaporized. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere. 'It sent soot travelling all around the world.

9. Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?

- I would say that it seems to me as though she does agree. I believe she has strong intentions to defend the earth and to prevent any more extinctions for any more animals. I believe she cares to explore and recover in order to hopefully help find a way to use asteroids to her advantage. On top of that, the object shown is an Irregular galaxy. This can be determined by the fact it has an irregular shape.

Answer:

1626.4 N

Explanation:

Given that a 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?

The parameters to be considered are:

Distance S = 3m

Time t = 0.55s

Since the man started from rest, initial velocity u = 0

Using second equation of motion

S = Ut + 1/2at^2

3 = 1/2 × a × 0.55^2

3 = 1/2 × a × 0.3025

a = 3/ 0.15125

a = 19.83 m/s^2

Force = mass × acceleration

Force = 82 × 19.83

Force = 1626.4 N

Therefore, the force that water exerted on him is 1626.4 N

Answer:

The equivalent resistance of the combination is R/100

Explanation:

Electric Resistance

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]

If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}[/tex]

This sum is repeated 10 times. Operating each term:

[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]

All the terms have the same denominator, thus:

[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]

Taking the reciprocals:

[tex]R_e=R/100[/tex]

The equivalent resistance of the combination is R/100

Answer:

Following are the solution to this question:

Explanation:

In this question, some of the information is missing that's why its solution can be defined as follows:

[tex]v= 0\\\\u= 1.0 \frac{m}{s} \\\\s= 1\\\\m= 54 \ kg\\[/tex]

Using formula:

[tex]\to v^2-u^2=2\cdot a\cdot s \\\\\to 0^2 - 1.0^2= 2 \cdot a \cdot 1\\\\\to - 1=2a\\\\\to a= -\frac{1}{2} \ \frac{m}{s^2}\\\\ \to \bold{F= m\cdot a}\\\\[/tex]

[tex]=54 \times - \frac{1}{2}\\\\= -27\ N[/tex]

Answer:

Explanation:

When we eat food, our body gets chemical energy from it. Now, this chemical energy from the food is changed into some different energy forms that is useful to it. They include:

-Chemical to mechanical energy to aid in movement of muscles

- chemical to thermal energy to aid in regulating the body temperature.

- chemical to electrical energy to aid the brain in thinking.

Thus is similar to how a machine converts energy because machines also generate energy after being powered and convert to other forms of energy. For example, an alarm clock converts electrical energy to sound energy, hair dryer converts electrical energy to thermal/heat energy.

Answer:

[tex]F=1.06\times 10^{-18}\ N[/tex]

Explanation:

Given that,

Mass of the Moon, [tex]M=7.34\times 10^2\ kg[/tex]

Mass of the person, m = 66 kg

The radius of Moon, [tex]r=1.74\times 10^6\ m[/tex]

We need to find the force between the person and the Moon. The formula for the gravitational force is given by :

[tex]F=G\dfrac{Mm}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.34\times 10^2\times 66}{(1.74\times 10^6)^2}\\\\=1.06\times 10^{-18}\ N[/tex]

So, the required force is [tex]1.06\times 10^{-18}\ N[/tex].
