The answer is A. the principal energy level
The principal energy level or principal quantum number n, tell us about the position of an determined electron in the energy levels relative to the greater average distance of an electron from the nucleus, the larger the value of n and the higher its energy.
The principal energy levels contains n sublevels, orbitals and electrons.
For example, the number 1, has one orbital which is contained in a energy sublevel, its called s orbital, and it's just an orbital with 2 electrons.
Have a nice day!
2.Chemical energy is converted to mechanical energy.
3. Chemical energy is converted to heat energy.
4. Chemical energy is converted to mechanical and kinetic energy.
the correct answer is 1. Chemical energy is converted to mechanical and heat energy.
When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.
Therefore the correct option is 1.
Answer:
Chemical energy is converted to mechanical and heat energy.
Explanation:
differences in pressure
B)
differences in temperature
C)
Earth's revolution round the Sun
D)
the Moon's revolution round Earth
Answer:
Correct Answer is B (Differences in temperature)
Explanation:
One of the main cause of ocean current to occur is variation of temperature of different layer of oceanic water.Water which have high temprature is less dense and this Less density water float above the surface of high density water. When this less density water reached on the surface of ocean that time wind which blows on the surface water makes the water cool or in other words we can say that water released its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water will moves upward. In this way this process will continue and hence ocean current is created.
Identify the concept that the angle above represents and explain what it means in your own words.
Answer:
its a compass rose or a temperature that tells how is it hot or cold or it is to u where to go when needed like a map.And the angles is 6
Explanation:
Linear momentum is a vector quantity defined as the product of an object’s mass and it's velocity
