Answer:
E = 1.1 10⁶ N / C
Explanation:
In this case they indicate that we can approximate the membrane as a parallel plate capacitor, we can use
E =
note that in this case the electric field created by each plate goes in the same direction, they are added
let's calculate
E =
E = 1.1 10⁶ N / C
Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
