Answer:
d = 0.343 m
Explanation:
Given that,
The speed of a longitudinal wave, v = 343 m/s
Your ear is capable of differentiating sounds that arrive at the ear just 1.00 milliseconds apart.
We need to find the minimum distance between two speakers that produce sounds that arrive at noticeably different times.
Let the distance be d. So,
So, the required distance is equal to 0.343 m.
Answer:
Explanation:
Assume the rod is horizontal
Sum vertical forces to zero
F - 8 - 4 - 2 - 3 = 0
F = 17 N
While this result answers precisely the question asked, it is not sufficient to guarantee equilibrium. We must also locate this force by summing moments to zero. Let's choose to sum about the left end.
8[9/2] + 4[1] + 2[6] + 3[4] - 17[x] = 0
x = 3.76470588...
the force must be supplied upward approximately 3.765 m from the left end
The rod does not actually have to be horizontal. Moment arms will all be proportionately reduced by tilting the bar from horizontal and the results will be identical. Assuming horizontal just reduces the calculation effort.
Earth's magnetic field is the force acting on the compass needle to cause it to point northeast.
