According to the values below, calculate the value of
R1 in this rectifier circuit with
zener diode:
- 42 v supply;
- Resistor 2 has 200 Omhs;
- Zener diode with regulating
voltage 7.5 v and maximum
current is 121 mA;

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
