An M=5.0x10-8kg dust particle that carries a Q=8.0x10-6C charge is placed in between two parallel plates that are equally but oppositely charged at a distance of 4.0cm from the (-) plate. The strength of this constant (uniform) electric field is E=12,500 N/C. Find the work done by the field on Q that pushes it toward the (-) plate through the 4.0cm distance.

A wedding website states that the average cost of a wedding is $ \$ 29,205 $. One concerned bride hopes that the average is less than reported. To see if her hope is correct, she surveys 36 recently married couples and finds that the average cost of weddings in the sample was $ \$ 27,338 $. Assuming that the population standard deviation is $ \$ 4532 $, is there sufficient evidence to support the bride's hope at the 0.02 level of significance? Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below. \[ \begin{array}{l} H_{0}: \mu=29,205 \\ H_{a}: \mu \quad 29,205 \end{array} \]

Give the balanced equation for each of the following. (Remember all symbols, i.e., states of matter, arrows) 1. The combustion of propanol, C4H9OH, forms carbon dioxide and water vapor. A combustion reaction refers to a reaction of a substance with oxygen gas. C4H9OH + 6O2 -> 4CO2 + 5H2O 2. Aqueous solutions of barium hydroxide and ammonium phosphate are mixed, resulting in the precipitate formation of barium phosphate with aqueous ammonium hydroxide as the other product. Ba(OH)2(aq) + (NH4)3PO4(aq) -> Ba3(PO4)2(s) + 6NH4OH(aq) 3. Solid Iron reacts with aqueous HClO4 to form aqueous iron(II) perchlorate and hydrogen gas. Fe(s) + 2HClO4(aq) -> Fe(ClO4)2(aq) + H2(g) 4. Aqueous calcium hydroxide reacts with aqueous hydrochloric acid to produce water and aqueous calcium chloride. Ca(OH)2(aq) + 2HCl(aq) -> 2H2O(l) + CaCl2(aq)
