It's possible to estimate the percentage of fat in the body by measuring the resistance of the upper leg rather than the upper arm; the calculation is similar. A person's leg measures 40cm between the knee and the hip, with an average leg diameter (ignoring bone and other poorly conducting tissue) of 12cm . A potential difference of 0.78V causes a current of 1.6mA . What are the fractions of muscle and fat in the leg? Express your answer using two significant figures separated by a comma. (%)

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
