<span>Plasma Basics. Plasmas are a lot like gases, but the atoms are different, because they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.</span>
Answer:
D because those are both concerning.
We will apply the equation:
2as = v² - u²
v = √(2as + u²)
v = √(2 x 4 x 400 + 13²)
v = 58 m/s
hope this helps
Answer:
![1.714\ \text{A}](https://tex.z-dn.net/?f=1.714%5C%20%5Ctext%7BA%7D)
Explanation:
F = Magnetic force = 0.018 N
B = Magnetic field = 0.03 T
L = Length of wire = 35 cm
= Angle between current and magnetic field = ![90^{\circ}](https://tex.z-dn.net/?f=90%5E%7B%5Ccirc%7D)
Magnetic force is given by
![F=IBL\sin\theta\\\Rightarrow I=\dfrac{F}{BL\sin\theta}\\\Rightarrow I=\dfrac{0.018}{0.03\times 35\times 10^{-2}\times \sin90^{\circ}}\\\Rightarrow I=1.714\ \text{A}](https://tex.z-dn.net/?f=F%3DIBL%5Csin%5Ctheta%5C%5C%5CRightarrow%20I%3D%5Cdfrac%7BF%7D%7BBL%5Csin%5Ctheta%7D%5C%5C%5CRightarrow%20I%3D%5Cdfrac%7B0.018%7D%7B0.03%5Ctimes%2035%5Ctimes%2010%5E%7B-2%7D%5Ctimes%20%5Csin90%5E%7B%5Ccirc%7D%7D%5C%5C%5CRightarrow%20I%3D1.714%5C%20%5Ctext%7BA%7D)
