Answer:
6000 cm<em>²</em>
Explanation:
let width of rectangle =
Using Pythagorean theorem,
+<em> 50² = 130²</em>
<em /><em> = 130² - 50² </em>
<em /><em> = 14400</em>
<em /> <em>= 120 cm</em>
area of rectangle <em>=</em> length x width
<em>=</em> <em>120 x 50</em>
<em>= 6000 cm²</em>
The characteristics of the speed of the traveling waves allows to find the result for the tension in the string is:
T = 10 N
The speed of a wave on a string is given by the relationship.
v =
Where v es the velocty, t is the tension ang μ is the lineal density.
They indicate that the length of the string is L = 2.28 m and the pulse makes 4 trips in a time of t = 0.849 s, since the speed of the pulse in the string is constant, we can use the uniform motion ratio, where the distance traveled e 4 L
v =
v =
v =
v = 10.7 m / s
Let's find the linear density of the string, which is the length of the mass divided by its mass.
μ =
μ = 8.77 10⁻² kg / m
The tension is:
T = v² μ
Let's calculate
T = 10.7² 8.77 10⁻²
T = 1 0 N
In conclusion using the characteristics of the velocity of the traveling waves we can find the result for the tension in the string is:
T = 10 N
