Uh it says physics but I'm pretty sure cause their is a tectonic plate right below California
Answer
current density is given by
where J = σ E
now,
a) Electric field strength at the inner surface of an iron cylinder
a = 0.5 cm = 0.005 m b = 2.3 = 0.023
L = 10 cm = 0.1 m I = 27 A
E = 8.59 x 10⁻⁴ V/m
b) Electric field strength at the outer surface of an iron cylinder
a = 0.5 cm = 0.005 m b = 2.3 = 0.023
L = 10 cm = 0.1 m I = 27 A
E =1.87 x 10⁻⁴ V/m
Answer:
30 seconds ahead.
Explanation:
Its about 90% of the decisions which are made by someone while driving based on what they see. The vision must be good to make the decision accurately and timely before reacting to the environment.
Line of sight is define as the view which you can see without any obstruction. The best condition of proper line of sight is that someone is needed to see in all direction front, behind, left and right.
To establish the clean line of sight the person should search the traffic environment about 30 seconds ahead.

Answer:
lamda=10.5m
Explanation:
using the equation of progressive wave.
y=Asin(wt-kx)
comparing the two equations together, we have
kx=0.6x , k=0.6
k=2π/λ
0.6=2*3.142/λ
cross multiply
0.6λ=6.284
divide both sides by 0.6
λ=6.284/0.6
λ=10.47m
approximate
λ=10.5m
