An artifact was found with 3.125 grams of CARBON-14 and 96.875 grams of NITROGEN-14. If the half-life of CARBON-14 is 5730 years, then how old is the artifact?

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?

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
