A sound wave is determined to have a frequency of 1,000 hz and wavelength of 35cm. what is the speed of this wave?

The speed of the sound wave is 350 m

Explanation:

Given

Frequency of sound wave = 1000Hz = 1000 (since 1 = 1 Hertz (Hz))

Wavelength of sound wave = 35 cm

Speed of sound wave = ?

All waves have same the relation among frequency, sound and speed which is given by

v=fλ , where

v is the speed

f is frequency

λ is wavelength

Therefore, the speed of sound wave = 1000 x 35 cm

                                                              = 35000 cm

                                                              = 350 m

Hence the speed of the sound wave is 350 m

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

find the sum of the two horizontal vectors and the sum of the two vertical vectors
