The pressure on a volume of liquidV=1.4m3at the surface is approximately equal to the atmospheric pressurePatm=1.00105N/m2. If this volume of liquid is now placed at a depth where the pressure i sP=2.50107N/m2, what will be the change in volume of the liquid? The bulk modulus of the liquid is 9.01010N/m2. (Include the appropriate sign with your answer.)
A tungsten wire has a radius of 0.065 mm and is heated from 20.0 to 1425 oC. The temperature coefficient of resistivity is ? = 4.5 x 10-3 (Co)-1. When 190 V is applied across the ends of the hot wire, a current of 1.4 A is produced. How long is the w..
