Question: The average power from a sound wave passing through an area of 1.16 m2 at a distance of 4.55 m from a source is 3.63 mW The sound wave is propagating isotropically in three dimensions through a gas with a density of 1.29 kg/m3. The wave has a speed of 330 m/s and a displacement amplitude of 5.39 nm at a distance of 4.55 m from...

i have some physics questions. hopefully you can answer these
all please.
A block with mass m = 2.0-kg attached to the end of a
spring undergoes simple harmonic motion on a horizontal
frictionless surface. The oscillation period is T = 5.5-s
and the oscillation amplitude is A = 13.8-cm. When the
spring is unstretched the block sits at a distance L =
2.2-m from a wall. Suppose we snap the spring at the very moment
the block passes through...

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....
