When all the strings on a guitar are stretched to the same tension, the speed of a wave along the most massive bass string will be B. slower.
<h3>How to explain the information?</h3>
It should be noted that the speed of the wave is inversely proportional to the square root of the linear density.
Therefore, when all the strings on a guitar are stretched to the same tension, the speed of a wave along the most massive bass string will be slower.
In conclusion, the correct option is B.

Answer:
W = 290.7 dynes*cm
Explanation:
d = 1/5 cm = 0.2 cm
The force is in function of the depth x:
F(x) = 1000 * (1 + 2*x)^2
We can expand that as:
F(x) = 1000 * (1 + 4*x + 4x^2)
F(x) = 1000 + 4000*x + 4000*x^2
Work is defined as
W = F * d
Since we have non constant force we integrate
W = [1000*x + 2000*x^2 + 1333*X^3] evaluated between 0 and 0.2
W = 1000*0.2 + 2000*0.2^2 + 1333*0.2^3 - 1000*0 - 2000*0^2 - 1333*0^3
W = 200 + 80 + 10.7 = 290.7 dynes*cm
Object will only form shadow if it won't reflect light.
That is, stone will form shadow as it reflects light.
