a. Explanation Given data: Distance between coyote’s ear is 15 cm, The bird is 3 m away, and The frequency of the whistle of the bird is 1000 Hz. Formula used: Write the expression for Pythagoras theorem. h = p 2 + b 2 (1) Here, h is the hypotenuse, p is the perpendicular, and b is the base. Write the expression for distance. t = d v (2) Here, t is the time, d is the distance, and v is the speed. Explanation: Consider the distance between coyote’s right ear and bird as the base of a right angled triangle, b = 3 m . Consider the distance between the ears as the perpendicular of the right angled triangle, p = 15 cm = 15 ( 1 cm ) = 15 ( 10 − 2 m ) { ∵ 1 cm = 10 − 2 m } = 0.15 m Substitute 3 m for b and 0.15 m for p in equation (1), h = ( 0.15 m ) 2 + 3 m 2 = 0 b. To determine The ratio of the time difference to the period of the sound wave.

1. The piston in the figure has a mass of 0.5 kg. The infinitely long cylinder is pushed upward at a constant velocity. The diameters of the cylinder and piston are 10 cm and 9 cm, respectively, and there is oil between them with v = 10⁻⁴ m^2/s and γ = 8,000 N/m³. At what speed must the cylinder ascend for the piston to remain at rest?
