Answer:
Explanation:
Given
Height from which cart is released is
as we know energy is Conserved and changes only its form so Potential Energy of Cart converted to kinetic Energy at bottom
Energy at Top
where m=mass of cart
g=acceleration due to gravity
h=height of track w.r.t bottom
Energy at bottom
cancel out common terms
Answer:
150mm
Explanation:
The correct answer to the given question is 150mm or 6 inch.
Atleast 150mm or 6 inches of a free conductor, measured from the point in box where it emerges from its cable sheath or raceway, must be left at each outlet, switch or junction point to lumination or connection of devices.
150mm of free conductor is required for the devices to be connected, this needs to be placed in the junctions
