Answer:
1) Unbalanced
2) Balance
3) Balanced
4) Unbalanced
5) Unbalanced
Explanation:
For 1 and 5, since the objects are not at a constant speed/velocity, their forces must be unbalanced.
For 2 and 3, their speeds are constant so that means the force is balanced. If the bycicle or box started accelerating, that would indicate an unbalanced force
For 4, the speed is constant, but it's direction is not indicating another unbalanced outside force causing it to turn. The force is unbalanced.
Answer:
c = 1 / √(ε₀*μ₀)
Explanation:
The speed of the electromagnetic wave in free space is given in terms of the permeability and the permittivity of free space by
c = 1 / √(ε₀*μ₀)
where the permeability of free space (μ₀) is a physical constant used often in electromagnetism and ε₀ is the permittivity of free space (a physical constant).
Answer:
D. Electromagnetic Induction.
Explanation:
The cones present on the retina are the cells that help you see the colors.....there are mainly three types....red blue and green, cones but they mix to generate different colours !
