Your friend’s six-month-old baby has begun to vocalize long strings of repeated syllables in a continuous stream. For example, the baby says “Malalalalalalamalamalamlamala.” The baby is in the ___________________ stage.

Ryan finds that he performs much better on his online tests if he studies in the same room where he will complete the test. Which of the following phenomenons describe Ryan’s finding.

A uniform magnetic field passes through a square loop of wire (side length 0.3 m) at an angle of 550 with respect to the plane of the loop.  The strength of the magnetic field is steadily increased from 4 T to 10 T in 2 s.  The resistance of the wire is 2 Ω.  What current is induced in the wire?

Who is most likely suffering from retrograde amnesia?

Which of these claims about memory is LEAST likely to be true?

Four-year-old Carla is playing a memory game with her mother. She proudly states she can easily remember where all 20 matching cards are. Carla is over confident about her perfect memory abilities because of her inadequate ___________.

Two point charges are located on the x-axis. Charge q1 = 6 uC is located at the origin and charge q2 = -3 uC is located at x = 2 m.  Find the magnitude of the force  that a 2 uC charge would experience if it were placed at y = 1 m on the y-axis (point (0,1)). (This is the same setup as last question)

A 3 uC charge is traveling with a velocity of 3 x 103 m/s in a uniform magnetic field .  The velocity is directed at an angle of 300 with respect to the magnetic field and the field has a magnitude of 0.8 T.  What is the magnitude of the magnetic force?

Two charged parallel plates are separated by 2 cm. The plates are charged and create a uniform electric field of 600 N/C between the plates. What is the potential difference between the plates?  

A long wire is carrying a current of 3 A a.  Calculate the magnitude of the magnetic field at point is a distance of 15 cm from the wire.
