Answer:
Explanation:
Let assume that pole vaulter begins running at a height of zero. The pole vaulter is modelled after the Principle of Energy Conservation:
The expression is simplified and final height is cleared within the equation:
![h_{B} = \frac{[(11\,\frac{m}{s} )^{2}-(1.3\,\frac{m}{s} )^{2}]}{2\cdot (9.807\,\frac{m}{s^{2}} )}](https://tex.z-dn.net/?f=h_%7BB%7D%20%3D%20%5Cfrac%7B%5B%2811%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D-%281.3%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D%5D%7D%7B2%5Ccdot%20%289.807%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%29%7D)
The unit of measurement for charge is Coulomb. Now, every particle of electron contains a charge equal to 1.602×10⁻¹⁹ <span>C. So if there are 3 electrons in the oil droplet, then the total charge would be:
Total charge = 3 electrons(</span>1.602×10⁻¹⁹ C/ electron)
Total charge = 4.806×10⁻¹⁹ C
If the object is moving in a straight line with constant speed,
that's a description of " acceleration = zero ".
Zero acceleration means zero net force on the object.
NO net force is 'required' to keep an object moving in a straight line
at constant speed. In fact, if there IS any net force on the object,
then either its speed or its direction MUST change ... there's no way
to avoid it.
None of this depends on the object's mass, or on the speed or direction
of its motion.
The oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.
<h3>What is the lithosphere?</h3>
The lithosphere can be defined as the outer rock layer present on the Earth's surface.
The oceanic lithosphere is composed of different rocks of the mantle such as, among others, gabbro and/or basalt.
The structure of the oceanic lithosphere is similar around the world because it is slender compared to the continental lithosphere and always determined by the supply of magma.
In conclusion, the oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.
