In an electric circuit, the free electrons are moving around. Since equal charges repel and opposite charges attract, the electrons move from the negatively charged to the positively charged pole of the voltage source.
Acceleration, a = (v - u)/t
where v is the final velocity, u is the initial velocity, and t is the time.
This formula on a velocity time graph represents the slope of the graph.
Answer:
Explanation:
The equations of equilibrium for the child are: (x' in the direction parallel to slope, y' in the direction perpendicular to slope)
After some algebraic manipulation, an expression for the coefficient of kinetic friction is obtained:
Answer:
C. microscope
Explanation:
A simple microscope is magnifying glass, an ordinary double convex lens having a short focal length that produces virtual and erect image.
