1. An ionization chamber is used on Tuesday (T=22°C, P=760mmHg) and then on Wednesday (T=25°C, P=740 mmHg) to monitor the output from an x-ray tube. If the output from the tube is identical on both days, then determine the chamber reading on Wednesday.
2. A condenser-type pocket ionization chamber is filled with air at STP. The chamber volume is 2cm3. The capacitance of the chamber is 5 pF. The voltage across the chamber before exposure to radiation is 180 V. The voltage across the chamber after the exposure is 160 V. What value is closest to the radiation exposure?
It is the property of a material by virtue of which it allows itself to be magnetized. Permeability varies from material to material depending upon the saturation and temperature.
Assume a 55.0-kg ice-skater, who was initially at rest, fires a 2.50-kg gun. The 0.045-kg bullet leaves the gun at a velocity of 565.0 m/s. What is the velocity of the ice-
