Given the distance r = 2/1000 m, the force between them F =
0.0104 N, the mass of the two object can be calculated using formula:
F = G(m1m2)/r^2 since the mass are equal F = G (m^2)/r^2
And where G = is the gravitational constant (6.67E-11 m3 s-2
kg-1)
The mass of the two objects are 24.96 kg
A cold acetic acid solution is used to wash the residue of
the reagent in preparation of an aldol condensation product after vacuum
filtration. The main reason in washing
with the acetic acid rinse is to neutralize any sodium hydroxide.
In photosynthesis, the water is being used to create food for the plant (Glucose). In transpiration the water is going from a liquid to a gas that's being released.
Answer:
<em>d. unchanged.</em>
Explanation:
The frequency of a wave is dependent on the speed of the wave and the wavelength of the wave. The frequency is characteristic for a wave, and does not change with distance. This is unlike the amplitude which determines the intensity, which decreases with distance.
In a wave, the velocity of propagation of a wave is the product of its wavelength and its frequency. The speed of sound does not change with distance, except when entering from one medium to another, and we can see from
v = fλ
that the frequency is tied to the wave, and does not change throughout the waveform.
where v is the speed of the sound wave
f is the frequency
λ is the wavelength of the sound wave.
Answer:
La velocidad angular del niño y del carrusel cuando se mueven juntos es 0.208 radianes por segundo.
Explanation:
Asumamos que tanto el niño como el carrusel no tienen carga externa aplicada sobre aquellos, de modo que se puede aplicar el Principio de Conservación de la Cantidad de Movimiento Angular:
(1)
Donde:
- Masa del niño, medida en kilogramos.
- Velocidad lineal inicial del niño, medida en metros por segundo.
- Radio máximo del carrusel, medida en metros.
- Momento de inercia del carrusel, medida en kilogramo-metros cuadrados.
- Velocidad angular final del sistema niño-carrusel, medida en radianes por segundo.
Si sabemos que 
, 
, 
y 
, tenemos que la velocidad angular final es:
La velocidad angular del niño y del carrusel cuando se mueven juntos es 0.208 radianes por segundo.
