A 100.0 mL sample of spring water was treated to convert anyiron present to . Addition of 25.00mL of a solution resulted in the reaction.
The excess wasback-titrated with 6.13 mL of a solution. Calculate the ppm of iron in the sample.
A circular conducting ring with radius
(a) Derive an expression, as a function oftime, for the total magnetic flux
(b) Determing the emf induced in the ring at time
(c) Because of the internal resistance of the ring, the currentthrough R at the time given in part (b) is only 3.00 mA.Determine the internal resistance of the ring.
(d) Determine the emf in the ring at a time
(e) Determine the time at which the current through Rreverses its direction.
Why does methyl benzoate dissolve in concentrated sulfuricacid. Write an equation showing the ions that are produced
A person standing at the top of a hemispherical rock of radius R = 13.00 m kicks a ball (initially at rest on the top of the rock) to give it horizontal velocity view as in the Figure
a) What must be its minimum initial speed if the ball is never to hit the rock after it is kicked?
b) With this initial speed, how far from the base of the rock does the ball hit the ground?
Transcripted image text displayed Uranium ions with a mass of 3.92 x 10–25 kg and a charge of 3.20 x 10–19 C are separated from similar species using a specific commercial mass spectrometer (see Sample Problem 28–3). The ions enter a uniform magnetic field after being propelled through a potential difference of 100 kV, where they are bent along a path with a radius of 1 m. They are gathered in a cup after turning 180 degrees and going through a slot that is 1 mm wide and 1 cm high. (A) What is the strength of the separator's (perpendicular) magnetic field? Calculate (b) the current of the required ions in the machine and (c) the thermal energy produced in the cup in 1.00 hours if the machine is used to separate out 100 mg of material each hour.
