Answer:
0.97 mole
Explanation:
1 mole will give 6.02×10^23 atoms
Xmole of tungsten will give 5.82×10^23 atom of tungsten
X= 5.82×10^23/ 6.02×10^23
X = 0.97 moles of tungsten
Answer:
The force increases because it is part of a Newton’s third law pair of forces with the force that the star exerts on the planet.
Explanation:
Force between two objects can be expressed by an equation:
F = G • m1 • m2 / r^2,
where m1 and m2 are objects' masses, r is the distance between them, and G is a gravitational constant.
That means that greater the masses or lesser the distance, the force will be greater, and vice versa.
This force exists between any two objects, but is generally extremely weak, so it's best observed with big and large objects with great mass, such as planets and stars.
This force, whatever its magnitude may be, always works on both objects, following the third Newton's law.
So, whatever the force the stat exerts on the planet is, the planet will exert the same amount of force on the star.
Answer:
d) All have identical pressures
Explanation:
The kinetic molecular theory explains how gas molecules behave in a container. By this theory, the gas particles behave like hard, spherical objects in a state of constant, random motion; these particles collide between them and at the walls of the container. Besides, the kinetic energy of the gas depends only on the temperature.
The pressure is the force that the particles are applying under some area, so by the theory, it depends on the number of moles (amount of particles that collides and make the force), the volume of the container and the kinetic energy, or the temperature.
Because all gases have the same number of moles and are at the same temperature and the same volume, they'll have the same pressure.
The theory of biological evolution known as Darwin's theory of evolution or Darwinism given by Charles Darwin an English naturalist. According to the theory, all the species of organisms develop and originate via the natural selection of minor, inherited changes, which enhances the tendency of an individual to survive, compete, and develop the tendency to give rise to new ones.
Thus, according to Darwin's theory of evolution in the given case of black and orange snakes, the black snakes will survive and reproduce, therefore, passing their traits to their offspring, while few orange snakes will remain in the population.
A molecular model is a three dimensional representation of a molecule. It shows all the atoms in the molecule.
The statements that can be supported by the information in the model are;
- The model shows a molecule with 14 atoms
- The model shows a molecule with two different elements
We can see from the model shown that there are white balls and black balls. Each ball represents an atom of an element.
There are 14 balls in total meaning that there are 14 atoms presents. Each color of balls stands for an element. There are two different colors in the model implying that there are two different kinds of elements in the molecule.
