Answer:
frequency= 165Hz
period=
Step-by-step explanation:
1. To calculate the frequency using the formula:
f = v/λ
where,
f=frequency (what the question asked)
v=speed of wave (given in the question=330m/s)
λ=wavelength (given in the question=2m)
SO,
= 165Hz
2. To calculate the period use the formula:
since
therefore,
where,
f= frequency (what we solved above=165Hz)
T= period (what the question asked)
SO,
The coordinates of the point that divides the segment into a 3:2 ratio is (-2.2, -1.2)
<h3>How to determine the coordinate?</h3>The points are given as:
G = (-4,3)
H = (-1,-4)
Ratio, m : n = 3 : 2
The coordinate of the point is calculated using:
This gives
Evaluate
Evaluate the product
(x,y) = (-2.2, -1.2)
Hence, the coordinate of the point is (-2.2, -1.2)
