Exercise 25.11 A 1.40 m cylindrical rod of diameter 0.450 cm is connected to a power supply that maintains a constant potential difference of 17.0 V across its ends, while an ammeter measures the current through it. You observe that at room temperature (20.0 ∘C) the ammeter reads 18.2 A, while at 92.0 ∘C it reads 17.1 A. You can ignore any thermal expansion of the rod. Part A Find the resistivity for the material of the rod at 20...

A 1.60 m cylindrical rod of
diameter 0.550 cm is connected to a power supply that maintains a
constant potential difference of 14.0 V across its ends, while an
ammeter measures the current through it. You observe that at room
temperature (20.0 ∘C) the ammeter reads 18.3 A , while at 92.0 ∘C
it reads 17.3 A . You can ignore any thermal expansion of the

In a water pistol, a piston drives water through a larger tube of radius 1.30 cm into a smaller tube of radius 1.50 mm as in the figure below. (a) If the pistol is fired horizontally at a height of 1.40 m, use ballistics to determine the time it takes water to travel from the nozzle to the ground. (Neglect air resistance and assume atmospheric pressure is 1.00 atm. Assume up is the positive y-direction. Indicate the direction with the...

Be sure to answer all parts. Asbestos is a fibrous silicate mineral with remarkably high tensile strength. But it is no longer used because airborne asbestos particles can cause lung cancer. Grunerite, a type of asbestos, has a tensile strength of 3.5 × 102 kg/mm2 (thus, a strand of grunerite with a 1−mm2 cross-sectional area can hold up to 3.5 × 102 kg). The tensile strengths of aluminum and Steel No. 5137 are 2.5 × 104 lb/in2 and 5.0 ×...
