Answer:
3.921*10^19 electrons
Explanation:
To find the number of electron that trough the car battery you first calculate the current by using the following formula, which relates the power with the voltage:
(1)
P: power of both headlights = 2(37.7W) = 75.4 W
I: current = ?
V: voltage of the battery = 12.0 V
You solve the equation (1) for I:
Next, you use the equivalence 1C = 6.241*10^18 electrons:
The number of electrons that cross the battery per second is 3.921*10^19 electrons
Answer:
Variations in electronegativity result in the unequal sharing of electrons in polar molecules because when one atom is more electronegative than the other, it becomes more polar than the other atom. ... Methane bonds are covalent because they share carbon and hydrogen valence electrons.xplanation:
Answer:
The answer is D.
Explanation:
Just like how cold air falls and warm air rises the same is with water.
Also the places with the coldest water is the north and south pole. The equator is relatively always warm so yeah.
Answer:
Speed is constant but velocity is changing
Explanation:
Speed is a scalar quantity, meaning magnitude only. Velocity is a vector quantity, meaning magnitude and direction. If you're moving in a circle at a constant speed, the speed is constant but the direction is constantly changing. Therefore, the speed is constant but velocity changes.
