A blue eyed man, both of his parents are brown eyed, married a brown eyed woman, whose father was brown eyed and whose mother was blue- eyed. What are the genotypes of everyone in the family? (Brown eyes are dominant to blue)

If a man is blue eyed (bb) then his parents are (Bb and Bb) because if they were BB and Bb, or BB and BB. Then there would not be any blue eye offspring.
And for the woman he married is brown eyed so she must be Bb or BB. Her mother is blue eyed so she is bb and her father is brown eyed so he must be BB and Bb. So how do you know if father is BB or Bb!

and
a right handed, blue eyed man, whose father was left handed, marries a left handed, brown eyed woman whose family members have been brown eyed for several generations.( right and brown are controlled by dominnant genes)
so my knowledge tells me that man is RRbb or Rrbb and his father is rr and man married a girl who is llBb or iiBB

A runaway truck lane heads uphill at 21 to the horizontal. If a 1.9×104 truck goes out of control and enters the lane going 120 , how far along the ramp does it go? Neglect friction.

Thanks in advance

we will be integrating GPS (garming 16-LVS) and INS (ADIS16355) that would be used for real time tracking of a vehicle. do you think this would be enough to provide a good result? Due to limits in budget what suggestions do you have?

Hi,

I guess this is two questions:

I can't help but wonder if there is some type of fundamental psychological requirement needed in order for mathematics to "click" in order for someone to learn mathematics to begin with. I have a desire to learn mathematics, but I just can not seem to catch on to how mathematics equates on higher levels of complication.
I believe that once I learn mathematics to its fullest potential, I will be able to accomplish nearly anything scientifically, theoretically or universally. I envision being able to understand so much more of the world around me... if I could only understand math.
Can someone explain to me how I might begin to learn mathematics, when mathematics has never "clicked" for me and is it possible that it will "click" for me if I just keep on trying?
Is my rationalization of envisioning my understanding of the world in a more heightend way accurate with regard to understanding mathematics?

A penny rides on top of a piston as it undergoes vertical simple harmonic motion with an amplitude of 4.0 cm. If the frequency is low, the penny rides up and down without difficulty. If the frequency is steadily increased, there comes a point at which the penny leaves the surface. What is the maximum frequency for which the penny just barely remains in place for the full cycle in Hz?

Lets face it - we have a finite supply of oil. There probably aren't going to be more Ghawars to be discovered.

We are going to run out of oil in about 25 years - less if nations like China and India continue to grow in use to the point that they emulate nations like the US.

Oil is so very vital to our society. If human civilization were a body, then oil would be its lifeblood. 95% of all transportation is oil based. The plastic industry is dependent on oil. Products like adhesives, explosives, pesticides, and more than I bother to keep track of come from this black liquid.

All of this of course contributes to global warming, but I am not going to go on about that here ... coal is more polluting, and so is natural gas (methane is released into the atmosphere during extraction)

Why does the world seem so ignorant on this reality? If we run out of oil, then it could represent the end of modern civilization, unless we seek alternatives ASAP. Why are we so foolish?

Natural increase is when a population rises because birthrate is higher then death rate.

Could anyone answer these two questions for me please? Thanks.

1. How can astronomers use the age of a lunar rock to estimate the age of the surface of a planet such as Mercury?

2. Charon stays in the same place in Pluto's sky, but the moon moves across Earth's sky. What causes this difference?

Thanks!
