The force between two celestial bodies is a Newtonian gravitational force.
It is also called Newton's law of universal gravitation. We can write it down mathematically in the following way:
We can see from this formula that gravitational force is <span>inversely proportional to the square of the distance between bodies.
The electrostatic force between two charges is Coulombs force. We can write it down like this:
</span>
This force is also inversely proportional to the square of the distance between interacting particles.
The nuclear force is a little bit more complicated. It can be expressed using the so-called Yukawa potential, which has the following form:
This interaction does not follow the inverse-square law.
The final answer should be 8.
Answer:
option (a)
Explanation:
There are some properties of charge given as
(a) Charges are of two types: negative charge and positive charge.
(b) Like charges repel each other and unlike charges attract each other.
(c) charges are conserved in nature.
(d) charges are quarantined.
So, the two charges which are opposite in nature can only attract each other.
So, if there is one negative and one positive charge, they always attract each other.
The force of attraction or repulsion between the two charges is given by the Coulomb's law.
Answer: Option (B) is the correct answer.
Explanation:
In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.
Hence, in solid substances the molecules have low kinetic energy.
Whereas in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
Hence, gases are able to expand more rapidly as compared to liquids.
Thus, we can conclude that out of the given options solid = low; liquid = medium; gas = high, combination of the state of matter and the corresponding dryer speed is correct.
Answer:
Bueno, sabemos que el volumen del monolito es 108m^3, y sabemos que el material es granito.
La densidad del granito es alrededor de 2.7 g/cm^3.
Entonces primero tenemos que convertir esto en m^3.
1m = 100cm
1m^3 = (100cm)^3 = 1000000cm^3.
1kg = 1000g.
Entonces tenemos el cambio de unidades:
2.7 g/cm^3 = 2.7*(1000000/1000) kg/m^3 = 2700 k/m^3.
y sabemos que:
densidad = masa/volumen
densidad*volumen = masa.
(2700kg/m^3)*108m^3 = 291600 kg.
