1.

A tube with a 1.00mm diameter filled with a saline solution of resistivity 9.75×10^-7?·m has an electric field of 22.5V/m when a potential difference is applied on either end of the tube.

what is the current flowing through the saline solution

2.

A tungsten wire of length (1/2)L and radius r is attached to another tungsten wire of length (1/2)L and radius 2r, forming one long wire of length L.

A potential difference is applied across the two ends of the combined wire. what is the ratio of the electric field within the wire of radius 2r to the electric field within the wire of radius r

1. If 55.1 cm of copper wire (diameter = 1.18 mm, resistivity = 1.69 × 10-8Ω·m) is formed into a circular loop and placed perpendicular to a uniform magnetic field that is increasing at the constant rate of 12.6 mT/s, at what rate is thermal energy generated in the loop? 2. A rectangular loop (area = 2.7 m2) turns in a uniform magnetic field, B = 3.2 T. When the angle between the field and the normal to the plane...

A pond 2 m in diameter is to be filled with water by a flow that varies linearly with the level of the pond so that it reaches the maximum value of 217 lt/h when the pond is empty and is zero when the level reaches 2 m. Calculate: a) Time it takes to reach the level of 1 m. b) Time it takes to fill up completely. Discuss this last result.

A small diameter tube closed at one end was filled with benzene to within 20 mm from the top of the tube and maintained at 295 K and atm pressure of 100 kPa with a gentle stream of air blowing across the top. After 30 kilo-seconds (30 x 103 s) the liquid level has fallen to 25.8 mm. The vapor pressure of benzene at 295 K is 13.3 kPa. Calculate the diffusivity of benzene in air. Density of benzene =...

What is the pH of a 1 x 10-7 M solution of HCl? Please note that you cannot simply add the contribution of H+ ions from the autoproteolysis of water and the contribution from the dissociation of HCl. You will need to use the quadratic equation to solve this problem and report the answer to 4 significant figures. For a hint see the Acids and Bases handout on Canvas.

A vertical glass tube of length L = 1.280000 m is half filled with a liquid at 20.000 000 degrees C. How much will the height of the liquid column change when the tube and liquid are heated to 30.000000 degrees C? Use coefficients alpha_glass = 1.000 000 x 10^-5/K and Beta_liquid = 4.000 000 x 10^-5/K
