A70 kg painter is painting the wall of a building. he stands on a horizontal board of length 6.3 m and mass 15 kg, suspended from vertical ropes attached to each end. if the painter stands 1.6 m from one end of the board, what would the tensions in the ropes be?

Suppose you plant a seed and observe that a tree of large mass grows from it.The tree achieves a final mass that changes very little for years afterward.which of the following is true about the tree. A Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing but then all reactions stopped when the tree reached a stable mass. B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass. C Only anabolic and catabolic reactions took place in the seed and tree when it was young and growing and only catabolic reactions continue now that the tree reached a stable mass D only catabolic reactions took place in the seed and tree when it was young and growing and only anabolic reactions continue now that the tree has reached a stable mass

this means that the temperature of both substances will be equal

in physics zero. in muscle fatigue could be high
