Answer:
The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Explanation:
Given that,
First frequency = 986 Hz
Second frequency = 1102 Hz
We need to calculate the length of the pipe
Using formula of length
Put the value into the formula
We need to calculate the fundamental frequency of this pipe
Put the value into the formula
Hence, The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Answer: A. Liquefied boils at a very low temperature (–253.7°C).
B. gas does not conduct electricity.
C. At room temperature, its density is less than that of any other gas.
Explanation:
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
Example: reacts vigorously with oxygen
to form water.
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
Example: Liquefied boils at a very low temperature (–253.7°C).It only changes state.
gas does not conduct electricity.It is only about movement of electrons.
At room temperature, density is less than that of any other gas. It is only about mass present per unit volume.
