Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
, n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
For second overtone, put n = 5
For third overtone, put n = 7
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
The area under the curve of a velocity-time graph gives us the <u>position of an object</u> to find the object's <u>displacement</u> specifically.
Therefore, <u>A: Position of an object</u> is the correct answer.
In electronics, the SI unit for current is Ampere. It is the amount of charge in Coulombs per unit time. It is named after the father of electrodynamics, Andre-Marie Ampere. Also, the current can be easily determined through the Ohm's Law, which states that current is equal to volts divided by the resistance. The answer is letter D.
Answer:19.34 miles
Explanation:
Given
First car travels with 32 mi/h
second travels with 54 mi/h
they leave at 2:00 Pm at 45
distance traveled by them is 0.5 hr
suppose First is traveling towards x axis and another travels 45 to it
Distance traveled by first car is
Position vector of first car after 0.5 hr
Position vector of second car after 0.5 hr
distance between them
distance between them
