...q. -y Que.... 3. A bumblebee falls into a pool and starts 'swimming' at 7.0 mm s-¹ on the surface of a puddle and creates a wave of frequency 2.7 Hz. The wave travels over the surface of the water at 32 mm s-¹. The diagram shows the wave pattern produced on the surface of the water. 7.0 mm S™¹ a. Calculate the frequency at which the waves will reach the edge of the puddle in front of the insect. b. Calculate the wavelength of the waves in front of the insect. C. At what speed, relative to the insect, do the waves travel behind the insect?

It's showing that b is not correct. Thank you for your help with this practice problem.

The measurement of a physical quantity is 4.76 m with 1.47% uncertainty. Therefore, the measurement is likely to be between: * 4.63 m and 4.78 m. O 4.67 m and 4.80 m. 4.69 m and 4.83 m. 4.71 m and 4.85 m. 4.73 m and 4.88 m.

Given that sin u = 1> V5 and cos u = -2>V5, use trigonometric identities to find the values of tan u, cot u, sec u, and cse u.

A stone is tossed into the air from ground level with an initial velocity of 30 m/s. Its height at time t is h(t) : 30t – 4.9t2 m. Compute the stone's average velocity ū in m/s over the time intervals [2, 2.01], [2,2.001], [2,2.0001] and [1.9999, 2], [1.999, 2], [1.99, 2]. (Use decimal notation. Give your answers to three decimal places.) Ū12,2.01] = m/s Ü12,2.001] = m/s U12,2.0001] = m/s
