Answer:
Explanation:
Using the Gauss Law, we obtain the electric Field for a uniform large line of charge:
We calculate the potential difference from the electric field:
Answer:
α = 1.32 rad/s²
Explanation:
given,
diameter of the bicycle = 0.8 m
radius of the bicycle = 0.4 m
initial speed of the bicyclist,u = 0 m/s
final speed of the bicyclist,v = 22 Km/h = 22 x 0.278
= 6.12 m/s
time,t = 11.6 s
acceleration =
=
=0.53 m/s²
we know,
a = α r
α = 1.32 rad/s²
the angular acceleration of the wheels is equal to α = 1.32 rad/s²

Bx=0Bx=0
By=8By=8
To find the distance b you want to find the vector that goes from A to 15 km E (vector C). Calling the differnce in A + B and C D, then we know
[math]D = (A + B) - C. So we have for D:
Dx=(Ax+Bx)â’Cx=â’1.8178Dx=(Ax+Bx)â’Cx=â’1.8178
Dy+(Ay+By)â’Cy=1.7883Dy+(Ay+By)â’Cy=1.7883
