You could just create a turn on green arrow. Have a button for pedestrians. The only way for them to turn is if they have a green arrow and the green arrow will only appear when pedestrians are stopped or finished walking and all cars are clear or fully stopped
Answer:
True
Explanation:
Principles of plasma arc cutting, Uses a constricting nozzle to create, concentrate, and direct the high-velocity plasma. Plasma gas is always used
in plasma arc cutting When shielding gas is also used, the process is called dual flow plasma arc cutting. I hope this helps.
Answer: Electric current originates from positively charged protons negatively charged electrons of an atom.
Explanation:
The movement of ions (positive or negative) from one point to another is called electric current.
An atom has three sub-atomic particles. These are protons, neutrons and electrons.
Protons are positively charged, neutrons have no charge and electrons are negatively charged. Protons and neutrons reside inside the nucleus of an atom whereas electrons revolve around the nucleus.
So, protons and electrons are responsible for originating electric current form an atom as these are the charged particles.
Thus, we can conclude that electric current originates from positively charged protons negatively charged electrons of an atom.
This question is incomplete, its missing an image which will be uploaded along this Answer.
Answer:
the normal component of force F_n is F((√(r²-s²)) / r)
the tangential component of force F_t is F(s/r)
Explanation:
Given the data in the image;
from the free body diagram, we write the expression for ∅
sin∅ = s/r
cos∅ = (√(r²-s²)) / r
now expression for normal component of force is;
F_n = Fcos∅
we substitute
F_n = F((√(r²-s²)) / r)
Therefore, the normal component of force F_n is F((√(r²-s²)) / r)
Also for force F_t
F_t = Fsin∅
we substitute
F_t = F(s/r)
Therefore, the tangential component of force F_t is F(s/r)
Hello!! The correct answer would be C!! I took the same test!
