Electrocardiographs are often connected as shown in Fig.19-55. The leads are said to be capacitively coupled. A timeconstant of 3.0s is tyical and allows rapid changes in potential tobe recorded accurately. If C = 3.0?F, What value must R have?

t=RC

$R=\frac{t}{C}$

$R=\frac{3\text{}\mathrm{sec}}{3.0\times {10}^{-6}}$ F

$R=1.0\times {10}^{6}$ ohms

A 15.0 kg block is dragged over a rough, horizontal surface by a70.0 N force acting at 20.0 degree angle above the horizontal. The block is displaced 5.0 m, and the coefficient of kinetic friction is 0.3. Find the work done on the block by ; a) the 70.0 N force,b) the normal force, and c) the gravitational force. d) what is the increase in the internal energy of the block-surface system due to friction? e) find the total change in the kinetic energy of the block.

Two blocks with masses 4.00 kg and 8.00 kg are connected by string and slide down a 30.0 degree inclined plane. The coefficient of kinetic friction between the 4.00-kg block and the plane is 0.25; that between the 8.00-kg block and the plane is 0.35.

a) Calculate the acceleration of each block

b) Calculate the tension in the string

c) What happens if the positions of the block are reversed, so that the 4.00-kg block is above the 8.00-kg block?

An 80.0-kg skydiver jumps out of a balloon at an altitude of1000 m and opens the parachute at an altitude of 200 m. (a) Assuming that the total retarding force on the diver is constant at 50.0 N with the parachute closed and constant at 3600 N with the parachute open, what is the speed of the diver whenhe lands on the ground? (b) Do you think the skydiver will be injured? Explain. (c) At what height should the parachute be opened so that the final speed of the skydiver when he hits the ground is 5.00m/s? (d) How realistic is the assumption that the total retarding force is constant? Explain.
