[answerhappygod]

task 2:Calculate the intensity of a wave at a
distance d = 2 • d knowing the intensity at
W
a distance de = 100m is I, = 1400
Task 3: Knowing intensity of a wave is
proportional to its amplitude? by what factor
does intensity increase/decrease (circle the
correct word) if amplitude decreases by a
factor of 4?
