A student-designed an experiment to determine if the length of the stick's shadow would change during the year. The shadow of the stick was measured at noon on the 20th of each month. Below is a table that shows the results of the experiment. What is the dependent variable in this investigation?

The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear

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?
