19.2642857143 MN/C, 2.697 MV
Explanation:
k = Coulomb constant =
Electric field at r = 8 cm
E = 0 (inside)
Electric potential is given by
Electric potential is 2.697 MV
r = 30 cm
Electric field is 4.1953 MN/C
Electric potential is 1.2586 MV
r = R = 14 cm
The electric field is 19.2642857143 MN/C
The potential is 2.697 MV

During the SUMMER in the northern hemisphere, the north pole is tilted toward the sun, making the sun appear higher in the sky.
Answer:
The average velocity of the ball is 1.355 cm/s.
Explanation:
Given;
initial displacement of the ball, x₁ = 8.4 cm
final displacement of the ball, x₂ = 4.2 cm
initial time, t₁ = 3.0 s
final time, t₂ = 6.1 s
The average velocity of the ball is calculated as;
Therefore, the average velocity of the ball is 1.355 cm/s.
