What are the answers I need this plz!!!!!
nope like genotypic ratio and phenotypic ratio....thanks though i figured it out...
THAT DIDN'T HELP!!!!!!!!!!!!!!!!!!!!
That didn't help. I meant like we have to make up our own problem to use on a quiz. She asked us to make 5 human genetic problems with answers but im not really sure what a problem like that would be like. Is that just the punnet squares and probability
thank you
i just want to find the number of revolutions , i know that 2 pi rad= 1 rev but how do we find that in this question.
a) 4.5/3= 1.5 s b) i'm still confused of how to get the number of revolutions c) a=v^2/r the answer is 5.4 m/s d) at=r alpha but we need to find alpha first to get at
how did you get the number 1355 for the sqrt of mass
Can you write the equations that you exactly used for each problem
thank for your help, I made it brief and straight to the point.
Yes, Thank you. You explianed everything, now where do I start?
THIS IS NOT MY HOMEWORK, I am having an interview for a job and they asked me this question. What would I document if this occurs.
