The speed of the carts descent will increase? Not quite sure what you’re asking.
Answer:
Explanation:
Given that
Bulk modulus ,K = 7.1 x 10¹⁰ Pa
The pressure P₁ = 0.781 x 10⁵ Pa
The final pressure P ₂ = 0 Pa
We know that bulk modulus given as
Now by putting the values
Therefore fractional change will be 11 x 10⁻⁷.
Answer:
Maximum 13 m overhang
Explanation:
Since the brick is uniform. Its mass must be equally distributed along its length. So the center of mass is in geometric center, which is 26 / 2 = 13 m from each end of the brick.
For the brick to not tip over, its center of mass must NOT be overhung over the edge. It stays just on the edge. So the maximum overhang is 13 m.
