The piano key is out of tune and has a frequency of 333 Hz.
The piano key is out of tune and has a frequency of 325 Hz.
The piano key is out of tune and has a frequency of either 325 or 333 Hz
The correct choice is
The piano key is out of tune and has a frequency of either 325 or 333 Hz
Beat frequency has been given as 4 Hz. hence the frequency must be above or below the given frequency of 329 Hz by 4 Hz. To get the upper level of frequency we add the beat frequency to the given frequency. To get the lower level, we subtract the beat frequency from the given frequency
f' = 329 + 4 = 333 Hz
and
f'' = 329 - 4 = 325 Hz
Current varies through all bulbs
There is no current through the bulbs
Current is the same through all bulbs
Answer:
Current is the same through all bulbs
Explanation:
Because it's a series circuit, the current traveling through the circuit doesn't change. In a parallel circuit, however, the current would not be the same due to the different 'paths' of the circuit.
Once the gas has dissipated, the vinegar and baking soda undergo a chemical transition that results in carbon dioxide.
According to thermochemistry, an exothermic reaction is one in which the overall standard enthalpy change (H) is negative. Heat is often produced via exothermic reactions. Once the gas has dissipated, the vinegar and baking soda undergo a chemical transition that results in carbon dioxide.
Bicarbonate (NaHCO3) is what makes baking soda and acetic acid in vinegar (HCH3COO). The carbon dioxide that results from this process is one of the byproducts that produce bubbles. A chemical reaction occurs when vinegar and baking soda are combined, producing carbon dioxide gas, which fills the balloon and causes it to expand.
Therefore, once the gas has dissipated, the vinegar and baking soda undergo a chemical transition that results in carbon dioxide.
