They're extremely small, occupying a very small volume, to the point where something like wind resistance that we think about with accelerating large objects like planes becomes completely irrelevant. A rogue electron can fly straight through most solid objects through the "empty space" between atoms. Their mass is also extremely small, 9.1*10⁻³¹ kg, making them relatively easy to accelerate to near light speeds (in comparison to other forms of matter) as it takes very little energy to set them into motion. Particle accelerators accelerate electrons to 99% of the speed of light in the real world every day.
Electrons are a stable sub atomic particle that has a negative charge and is found in all atoms and is the main carrier of electricity through solids.
In a metal, some of the electrons can escape from the atoms and are free to move around inside the metal. These electrons are referred to as 'conduction electrons'.
<span>A current is a flow of charge. In metal a current is the flow of the conduction electrons through the metal. This can occur when connected to battery for example: The battery pumps the conduction electrons around the circuit. </span>
The answer is B. Snake.
Hope this helps!
Answer:
By 1000 joules
Explanation:
Given
Required
By how much does her GPA increases
To do this, we simply calculate the potential energy.
Where
At the ground level, the height is 0
i.e. 
So:
At:
So, we have:
Calculate the difference
<em>Hence, it increases by 1000 joules</em>
Answer:
7] Force = mass × acceleration
Force = 2 × 5
<u>Force = 10 N</u>
<u></u>
8] Velocity = acceleration due to gravity × time taken
Velocity = 9.8 × 12
<u>Velocity = 117.6 m/s</u>
