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,
Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
