Answer:
Explanation:
Time for one dot = 1 /50 = .02 s
Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s
velocity = 3 cm / .02 = 150 cm /s
Distance between 4 th and 5 th dot is 4 cm and time taken to travel this distance is .02 s
velocity = 4 cm / .02 = 200 cm /s
change in velocity = 200 cm/s - 150cm/s = 50 cm /s
Time taken = .02 s
Acceleration = 50 / .02 cm/s²
= 2500 cm/s²
<u>Explanation</u>:
The text is in Romanian language, however here's a clearer rendering which reads;
<em>"From 2 coherent sources at a distance d = 2 meters from each other, it propagates in an elastic medium where with velocity = 340 m/s. At a distance L = 4 meters from the middle between sources perpendicular to the segment joining them a maximum of interference and the next at a distance of 1.5 meters from it on the line parallel to the one on which the sources are located. What is the frequency of oscillation of the sources?."</em>
