Answer:

442 Hz, 882 Hz, 1330 Hz

Explanation:

Given data:  length of the string= 0.31 m = 31 cm

speed of the waves = 274.4 M/s or 2740 cm/s

Wavelengths are

62 cm

31 cm and

62 / 3  =  20.67 cm

The frequencies associated with these wavelengths ( which are the 1st, 2nd and 3rd harmonics )

are

27440/ 62 =  442.6 = 442 Hz

27440/31  = 885.2  = 882 Hz

27440 / 20.67  = 1328 = 1330 Hz

The two-second rule applies to any speed __________ A. in all weather conditions. B. in ideal weather and road conditions. C. in
kumpel [21]

Answer:

The answer is A

Explanation:

A large risk of tailgating is the collision avoidance time being much less than the driver reaction time. Driving instructors advocate that drivers always use the "two-second rule" regardless of speed or the type of road. During adverse weather, downhill slopes, or hazardous conditions such as black ice, it is important to maintain an even greater distance.
