<h3><u>Answer;</u></h3>

<em>A mixture </em>

<h3><u>Explanation;</u></h3>
  • <em><u>A mixture is a substance that is made of two or more substances. </u></em>A mixture may be homogeneous in which substances in the mixture are in the same phase, or may be heterogeneous where substances in the mixture are not in the same phase, such as suspensions and colloids. <u><em>Therefore mixtures are not pure substances.</em></u>
  • A pure substance is a substance that contains atoms or molecules of the same element or compound.<em><u> Examples of pure substances are elements, compounds and also atoms.</u></em>

An apparatus like the one Cavendish used to find G has large lead balls that are 5.2 kg in mass and small ones that are 0.046 kg.
Ber [7]

Answer:

The magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N.

Explanation:

Given that,

Mass of first lead ball, m_1=5.2\ kg

Mass of the other lead ball, m_2=0.046\ kg

The center of a large ball is separated by 0.057 m from the center of a small ball, r = 0.057 m

We need to find the magnitude of the gravitational force between the masses. It is given by the formula of the gravitational force. It is given by :

F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67259\times 10^{-11}\times \dfrac{5.2\times 0.046}{(0.057)^2}\\\\F=4.91\times 10^{-9}\ N

So, the magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N. Hence, this is the required solution.

Alik [6]

Answer:

the Voltages become negative instead of positive but the magnitude remains the same.

Explanation:

If we remove  the positive charge by dragging it back to the box at the bottom, and drag a negative charge (blue) toward the middle of the screen, the Voltages become negative instead of positive but the magnitude remains the same.
