The answer is equal and opposite forces.
Answer:
The molecular formula for the compound is C4H8.
Explanation:
Emperical formula is CH2
Molar mass = 56 g/mol
Molar mass = (CH2)n
56 = (12 + 1×2)n
56 = (12 + 2)n
14n = 56
n = 56/14 = 4
Molecular formula = (CH2)n = (CH2)4 = C4H8
Answer:
10 to 15 seconds
Explanation:
because I don't know but rarity is a strong force and it don't take long for a ball to come down
Answer:
f = 409 Hz
Explanation:
We have,
Length of the open organ pipe, l = 0.29 m
Frequency of vibration of second overtone,
It is required to find the fundamental frequency of the pipe. For the open organ pipe, the frequency of second overtone is given by :
v is speed of sound
Let f is the fundamental frequency. It is given by :
The relation between f and f₂ can be written as :
So, the fundamental frequency of the pipe is 409 Hz.
