electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 1.2 x 10-8 C and they are separated by a distance of 0.40 m. 2. Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 6.5 x 10-7 C and they are separated by a distance of 2.50 m.

There were many different scientific advances during the late 19th century‚ but one specific scientific advance that I will be discussing is the discovery of physics through X-rays and radiation‚ which was discovered by Wilhelm Röntgen. After he published a paper on his discovery of X-rays in 1895‚ there was great study and research done by physicists such as: Antonie Henri Becquerel‚ Marie Curie‚ and Ernest Rutherford on radioactivity and the formation of radiation through x-rays. Although Wilhelm

roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to move toward the negatively charged roller‚ but the belt is in the way. So now the belt gets "coated" with the positive charge‚ which it then carries away from the roller. The belt is positively charged

Charging by Induction Purpose: To determine the kind of charge induced on a neutral object when it is approached by a charged object. Materials: • metal-leaf electroscope • ebonite rod • fur • glass rod • silk • human finger (with body) Procedure: 1. The metal-leaf electroscope was approached‚ but not touched‚ by a negatively charged ebonite rod. The rod was moved toward and away from the metal ball on the electroscope several times. Observations were recorded

inhumanity of the death penalty‚ including the barbaric methods and public spectacle of the act prior to William Kemmler‚ and most importantly‚ the safety and efficacy of direct current versus alternating current in the eventually preferred method of the electric chair. Thomas Edison and George Westinghouse‚ along with a few others‚ were the players who manipulated how the public‚ and therefore the lawmakers‚ felt about this social policy. As it is today‚ the death penalty was a big debate issue in the

a negative charge and if pH < pI‚ the protein will have a positive charge. Buffer I has a pH >5‚ meaning both proteins carry a negative charge and bind to the DEAE (a positively charged resin). (b) pH = pKa + log10(Base/Acid) [Base = mM of sodium acetate; Acid = mM of acetic acid] = 4.7 + log10 (40/40) = 4.7 In order for the catalase to elute from the column‚ it must have lost its negative charge and stopped binding to the DEAE. Lowering the pH nullifies the negative charge on the protein

But there is an opportunity for us in price. Even though they have automation of ten they are still charging 30 for their low tech products. This is an opportunity for us to charge less! What actions should you take to compete with this competitor more effectively? We also have automation of ten and are going to charge less‚ and spend a lot on our sales so out product is much more accessible. Our products are pretty much the same so because we are charging less we should be able to take some
