An apparatus like the one Cavendish used to find G has large lead balls that are 7.2 kg in mass and small ones that are 0.053 kg

uranmaximum [27]

Answer:

$6.41537\times 10^{-9}N$

Explanation:

Given that $G=6.67259\times 10^{-11}Nm^2/kg$ , we can use Newton's Universal law of gravitation to determine the magnitude of the gravitational force as:

$F=G\frac{m_1m_2}{r^2}\\\\\\=G=6.67259\times 10^{-11}Nm^2/kg\frac{7.2kg\times 0.053kg}{(0.063m)^2}\\\\\\=6.41537\times 10^{-9}N$

Hence, the magnitude of the gravitational force between the masses is $6.41537\times 10^{-9}N$

sladkih [1.3K]

Answer:

The student hears the wave that is transmitted by the desk

Explanation:

Mechanical waves need a material medium to be able to be transmitted, in the case of sound waves, one of the most common media is air, but it is also transmitted in other media in this case, stationery is transmitted.

The student hears the wave that is transmitted by the desk

The speed of the wave is proportional to the density of the material, so the wave that the student hears arrives much faster through the desk than through the air
