Answer:
Explanation:
From the question we are told that
Temp of first bolts
Temp of 2nd bolt
Generally the equation showing the relationship between heat & temperature is given by
Generally heat released by the iron bolt = heat gained by the iron bolt
Generally solving mathematically
Therefore is the final temperature inside the container
Answer:
1/3 the distance from the fulcrum
Explanation:
On a balanced seesaw, the torques around the fulcrum calculated on one side and on another side must be equal. This means that:
where
W1 is the weight of the boy
d1 is its distance from the fulcrum
W2 is the weight of his partner
d2 is the distance of the partner from the fulcrum
In this problem, we know that the boy is three times as heavy as his partner, so
If we substitute this into the equation, we find:
and by simplifying:
which means that the boy sits at 1/3 the distance from the fulcrum.
