Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
Answer:
Option B
It converts light into electric current
Explanation:
A photometer is a device used to measure illuminance
Its principle of operation hinges on the conversion of light into electric current, using photoresistor or any other light sensitive device such as a photodiode. This is so that it can be read off easily by any other device.
A Photoresistor is a device that changes the flow of current through it when it is exposed to light rays. A photometer works by irradiating a photo resistor, which then converts the light rays incident on it to electric current.
Answer:
what do you mean ???????????
Let's call
the frequency of the nth-harmonic and
the frequency of the (n+1)th harmonic, wish is the next harmonic.
Since the frequency of the nth-harmonic is n times the fundamental frequency f1:
then the difference between two successive harmonics is equal to the fundamental frequency of the tube:
so, by using 350 Hz and 280 Hz as successive harmonics, we find the fundamental frequency of the tube:
The wavelength of the first harmonic is twice the length of the tube:
And since we know both frequency and wavelength, we can find the speed of the wave in the tube, which is the speed of sound in the gas in the tube:
Answer:
a. no lift
Explanation:
To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.
