Answer:

will mostly accord at the top of the boiling water my kind sir

Explanation:

Evaporation takes place only at the surface of a liquid, whereas boiling may occur throughout the liquid. In boiling, the change of state takes place at any point in the liquid where bubbles form. The bubbles then rise and break at the surface of the liquid.

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.

Describe how substance move from one state to another
Mekhanik [1.2K]
The temperature rises until the water reaches the next change of state — boiling. As the particles move faster and faster, they begin to break the attractive forces between each otherand move freely as steam — a gas. The process by which a substance moves from the liquid state to the gaseousstate is called boiling.

A force exerted on an object produces acceleration. If the mass remains the same and the acceleration is doubled, the force must
Inga [223]
<h2>Answer</h2>

The force will be doubled.

<h2>Explanation</h2>

Using Newton Law II,

<h3>F = ma </h3>

So it can be seen in the formula that force is directly proportional to mass and acceleration.

if mass is doubled ---> force will be doubled, keeping acceleration constant.

Similarly,

if acceleration is doubled ---? force is will be doubled, keeping mass constant.

<em>It is assumed that there is no friction, the object is in the air with no air resistance.</em>
