Surface of a sphere=4πr²
volume of a sphere=(4/3)πr³
Data:
surface area =432 m²
volume=864 m³
ratio of surface area to volume=surface area / volume
ratio=432 / 864 =0.5
Answer. The ratio would be 0.5
Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz
Answer:
the number of neutrons in an atom of the element is 10.
Explanation:
neutron: mass # -protons
neutron: 19 (18.9984 (rounded)) - 9
neutron: 19- 9 =10
whole number is equal to the number of protons.
Answer:
\A.
