It would be B since it starts with the solar energy which is converted to electricity with the solar panels, which then creates mechanical energy for the fans blades to move and sound for the radio.
Hope that helps :)
Answer:
Explanation:
P = Acoustic power = 63 µW
r = Distance to the sound source = 210 m
Acoustic power
Threshold intensity = 
Ratio
Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68
Answer:
Volt
Explanation:
Electric Potential is the Voltage and it's measured in volt
When the number of electrons striking the anode of an X-ray tube is increased, the density of the emitted x-ray increases
32t + 148 = 0148 = 32t4.625 = tt ≈ 4.63h = -16 • (4.625)^2 + 148 • 4.625 + 30 = 372.25
ANSWER: is D. 4.63 sec; 372.25 ft
2.) 2x - 4 = 0 and 2x - 1 = 0x = {4/2, ½}x = {2,½} ANSWER: is B 2, 1 over 2
