The cloud chamber is filled with isopropyl alcohol vapor. the chamber is warm at the top, extremely cold at the bottom. at a certain height, the temperature is low enough that the vapor will condense to make droplets, a cloud, if there is something for a droplet to form on, a nucleation site. this can be a dust particle, or the ions produced by ionizing radiation traversing the chamber. this is the source of the trails of cloud that appear in the chamber; these are the tracks of high-energy charged particles. if you compared the track of an alpha particle and a beta particle, the track of the alpha particle would be but the track of the beta particle would be

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
