Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far fro

Answer:
527Hz
Explanation:
The beat frequency of any two waves is:
Fbeat =|f1 – f2|
i.e
for frequency tied to length increase (wavelength increases as length increases, therefore frequency decrease:: Fbeat = f1+f2
for frequency tied to length decrease wavelength increases as length increases, therefore frequency also increases : Fbeat = f1-f2
Note that a wavelength increase means a decrease of frequency because v = fλ
Therefore from the question:
Fbeat =4 beats/s
F2 -523Hz
Fbeat = f1-f2
F1=Fbeat+F2
=523+4
=527Hz
Answer:
Hydrogen gas/bubbles
Explanation:
Photosynthesis is defined as the process by which green plants and other organisms like blue-green algae etc. synthesize organic matter. In the presence of light energy, they convert CO2 and H2O into organic sugar with the release of O2 gas.
The plant was performing photosynthesis since there is the presence of CO2 (baking soda) and water and therefore the bubbles seen is hydrogen gas guven off from photosynthesis .
6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)
To solve this problem it is necessary to apply the concepts related to Ohm's Law to find the voltage in the case of direct current. While for the Alternate current we use the concept of RMS voltage.
PART A) In the case of DC we have to,
V=IR
Where,
I = Current
R = Resistance
Where the current is 60mA y the resistance is 
, then the potential would be
In the case of DC we have that the current and the RMS voltage is,
The potential in AC then is,
