Answer:
Symbol N
Explanation:
The SI unit of force is the newton, symbol N
Answer:
Its shape is not fixed
Explanation:
Plasma is sometimes a subset of gases, whereas it is also a state of matter.
These two states are different.
No fixed shape for plasmas, no fixed volume.
Compared to solids and liquids plasmas are less dense.
Atoms are used in the making of Plasma.
In plasma state ions are the positively charged nuclei
When they gain or lose electrons these atoms and molecules acquire a positive or negative electrical charge, process is called ionization.
Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 26 m/s
Final velocity (
V2) = 0 ft/s because the car comes to a complete stop!
Time (
t) = 6 seconds
The equation for acceleration is below!
a =
So now, just plug in the values!
a =
a =
a = -4.33 m/s²
Therefore, your acceleration is -4.33 m/s²!! Hope this helped and was one of the branliest answers :')
Answer:
option A
Explanation:
A soccer field is about 100 meters of length, with the other instruments is possible to make the measure, but it will be very complex and it will take time. Therefore with the 50-m tape, the student will need only two measures.
Answer:
ionized particles from the sun.
* interactions in radiation belts.
* the friction of the planet in the solar wind
q = +9 10⁵ C
Explanation:
Due to being made up of matter, the planet Earth has a series of positive and negative charges, in general these charges should be balanced and the net charge of the planet should be zero, but there are several phenomena that introduce unbalanced charges, for example:
* ionized particles from the sun.
* interactions in radiation belts.
* the friction of the planet in the solar wind
This creates that the planet has a net electrical load
We can roughly calculate the charge of the planet
E = k q / r²
q = E r² / k
let's calculate
q = 200 (6.37 10⁶)²/9 10⁹
q = +9 10⁵ C
