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.
out onto the rear seats. Why does this happen?
Answer:
See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
Answer:
This happens because of inertia.
Explanation:
Inertia is the ability of a body to remain in its state of rest or relative movement, while an external force is not acting on it.
It is when a body objects to modifying its state of relative rest or movement, including the speed and direction in which this happens.
When a car accelerates, a cup of coffee sitting in a cup-holder spills out onto the rear seats, because it has left its state of rest due to the acceleration force of the car.
A nitrogen atom contains 7 protons, 7 electrons and 7 neutrons.
Electrons are defined as subatomic particles with a negative elementary electric charge that belong to the first generation of the lepton particle family, and are considered elementary particles because they have no known constituents or substructures.
A proton is defined as a stable subatomic particle, symbol p, H⁺, or ¹H⁺, having a positive electric charge of +1 e elementary charge, with a mass slightly less than that of a neutron and the mass of an electron is 1,836 times.
A neutron is defined as a subatomic particle found in the nucleus of every atom except simple hydrogen, where the particle derives its name from the fact that it has no electric charge as it is neutral. Neutrons are very dense. Atoms contains same number of protons, electrons and neutrons like in nitrogen.
Thus, a nitrogen atom contains 7 protons, 7 electrons and 7 neutrons.

To convert from Celcius to Kelvin just add 273
-30C + 273 = 243 Kelvin
10C + 273 = 283 Kelvin
50C + 273 = 323 Kelvin
To convert from Celcius to Fahrenheit is C * 1.8 +32
-30C * 1.8 + 32 = -22F
10C * 1.8 + 32 = 50F
50C * 1.8 + 32 = 122F
Hope that helps!
