A gry is an old English measure for length, defined as 1/10 of a line, where line is another old English measure for length, defined as 1/12 inch. A common measure for length in the publishing business is a point, defined as 1/72 inch. What is an area of 0.68 gry2 in points squared?

why a neuron’s voltage returns to about -70 mV following a graded potential that does not cause voltage to reach threshold.

a.      why a neuron’s voltage returns to about -70 mV following a graded potential that does not cause voltage to reach threshold. That is to say, what changes in ion flow occur before RMP before RMP is reached? Why is there no net movement of ions (except via the pump and continuous inflow of sodium) once RMP is reached? 

b. if the RMP would increase, decrease, or stay the same if the sodium-potassium ATPases stop working for several hours. What is the rationale for your prediction? How would the persistent failure of the pumps influence the ability of the neuron to generate action potentials? (Assume that the neuron will not burst because of a possible increase in the concentration of ions in the neuron.) reached? Why is there no net movement of ions (except via the pump and continuous inflow of sodium) once RMP is reached?

A friend has learned that you are studying genetics, and she is into genealogy.

A friend has learned that you are studying genetics, and she is into genealogy. Her family has been in Maine for at least three generations, and she can trace her heritage back to a couple living on Mohegan Island.

She did notice something odd in her family, and you showed her how to draw a pedigree.

What is unusual about her family’s pedigree?

Can you explain this pattern with Mendelian inheritance?  If yes, then what is a possible explanation?

  1. A skier, mass 61.00 kg is at the top of a hill and starts down with an initial speed of 3.1m/s. He does no work on the way down. Assume that the hill surface is frictionless. Find his speed at the bottom of the hill which is 15m below the top.
  2. A bloc of mass 1 kg moves on a frictionless incline ( none of the forces on the block are shown). It’s intial velocity is v_0=2m/s, and it slides a vertical distance h=5m up the slope and its final velocity is v_f=4m/s. Find the external work done on the block.
  3. A baseball outfielder throws a baseball of mass 0.18kg at speed of 39m/s and initial angle of 25 degrees. What is the kinetic energy of the baseball at the highest point of the trajectory? Ignore air friction.

Two cars each of mass 1300 kg are approaching each other on a head on collision course. Each speedometer read 19m/s. What is the magnitude of the total momentum of the system?I know the answer is 0 but I am confused as to what formula leads me to that answer. Is it -p1=p2?

But the direction of the magnetic field is different. If your right thumb points along the current, the magnetic field curls around the wire in the direction of your fingers. A power line carries a current of 97 A west along the tops of 9.0 m-high poles. What is the direction and the magnitude of the magnetic field produced at the ground?

I need some help with this question, specifically what it is asking. Is it asking us to write the mechanism for the reactions or just present what reagents are used? Please give some steps and reasoning for the first question as well.
