Answer:
Answer c. 1.4 mm
Explanation:
Notice that the addition of these two waves are equivalent to adding a sine wave plus a sine wave shifted by pi/2.
The maximum of such addition will come from twice the y value of the two functions at the point of intersect that takes place at about one grid unit to the right of the vertical axis. That intersection reads about 0.7 mm for the y value (which corresponds to an x of about pi/4)
Then, the addition of both y-values will give an amplitude of 1.4 mm
Haven't taken physics but I would assume if her friend is standing in front of her that you would add up the speeds and get 30 km/hr.

According to the seismograph recording of an earthquake shown above, we can conclude the following about this particular earthquake:
A.) The P-waves arrived at 24 min, the S- waves arrived at 27 min, the P-waves had a larger amplitude than the S- waves, and therefore the P- waves carried more energy than the S-waves.
B.) The P-waves arrived at 24 min, the S-waves arrived at 27 min, the S-waves had a larger amplitude than the P-waves, and therefore the S-waves carried more energy than the P-waves.
C.) The P-waves arrived at 9hrs 24min, the S-waves arrived at 9hrs 27 min, the P-waves had a larger amplitude than the S-waves, and therefore the P- waves carried less energy than the S-waves.
D.) The P-waves arrived at 9hrs 24min, the S-waves arrived at 9hrs 27min, the S-waves had a larger amplitude than the P-waves, and therefore the S-waves carried more energy than the P-waves.

Humberto should expect to see that all bulbs in circuit 1 will shine more dimly than the original bulbs, while all bulbs in circuit 2 will have the same brightness as the original bulbs.
B) All bulbs in circuit 1 will shine more dimly than the original bulbs, while all bulbs in circuit 2 will have the same brightness as the original bulbs.
