Answer:
It increases by four times the initial amplitude.
Explanation:
The amplitude of a sounde is inversely proportional to the square of the distance between the listener and the sound source:
In this problem, the distance is decreased to hald the initial distance, so we can write
therefore, the new amplitude will be
So, the amplitude increases by a factor 4.
Displacement is the amount of "ground" and object moves from it starting point and distance is how much "ground" an object covers in total. Displacement by definition is moving of something from its place or position and distance by definition is the amount of space between two things (in this case the starting position and ending position).ΥΤ-ΤΟΝΙХWΙLSΟΝ
Electric field due to a charged rod along its axis is given by
here we know that
L = 14 cm
r = distance from end of rod
r = 36 - 7 = 29 cm
Q = 222 mC
now we will have
Answer:
Explanation:
The fish falls from vertical rest in a time of
t = √(2h/g) = √(2(2.27)/9.81) = 0.68 s
v = d/t = 5.6 / 0.68 = 8.2 m/s
