Which type of reaction does this diagram represent?
A small ball heads toward a large circle labeled superscript 235 upper U. An arrow points to an irregular circle labeled superscript 236 upper U. Another arrow points to a starburst, partially overlaid by 2 blobs labeled superscript 92 upper K r and superscript 141 upper B a, and with 3 small balls heading away from the starburst.
nuclear fusion because nuclei combine to form a heavy nucleus
nuclear fission because an atom is splitting into two large fragments of comparable mass
nuclear fusion because a large amount of energy is being released
nuclear fission because the resulting products are not radioactive

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ât. the resistance of the coil is r, and the total charge is q = iât, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly âswipedâ past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be âswipedâ through the reader at exactly the right speed? why or why not?

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?

A2.0 Îźf capacitor and a 4.0 Îźf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
