The speed of sound is given by the formula
Speed of sound = square root (Young's Modulus/density)
Young's modulus for gold = 78 GPa which is 7.8 * 10^10 Pa
Speed of sound = (7.8 * 10^10 / 19.3 ) = sqrt (4.04 * 10^9 )
Speed of sound = 6.36 * 10^4 m/s <<<=== answer.

hi !!!!!!!!!!!!!!!!!!!!!!!!!!!
thanks for the points
Answer: mutualism
Explanation: animals pollinating flowers is an example of a mutualistic relationship since both the flower and pollinator benefit from one an other. In the plant-pollinator relationship, Flowers provide the pollinator with nectar and pollen, which the pollinators then collect for feeding; and the pollinators provide flowers with the means to reproduce, by spreading pollen from flower to flower.
