The Nazca plate will move under the south american plate. i know its late but it will help others!
The type of current produced by a battery is direct current. C.
Answer:
Angular frequency is 20 rad/s.
Explanation:
Given that,
A block is attached to an oscillating spring. The function below shows its position (cm) vs. time (s) is given by :
.....(1)
The general equation of oscillating particle is given by :
.......(2)
Compare equation (1) and (2) we get :
So, the angular frequency of the oscillation is 20 rad/s.
Answer:
Explanation:
The volume charge density is defined by ρ = (Equation A), where Q is the charge and V, the volume.
The units in the S.I. are , so we have to express the radius in meters:
inner radius =
outer radius =
Now, we know that the volume of the sphere is calculated by the formula:
, and as we have an spherical shell, the volume is calculated by the difference between the outher and inner spheres:
V = , where is the outer radius and is the inner radius.
Replacing the volume formula in the Equation A:
ρ =
ρ =
Replacing the values of the outer and inner radius whe have:
ρ =
ρ =
Answer: The size of the force varies inversely as the distance square between the two charges. Thus, if the distance between the two charges is doubled, the attraction or repulsion will become weaker and decrease to one-fourth of the original value. The size of the force shall be proportional to the value of each charge.
