Answer:

1.16 .

Explanation:

In the  product of two or more physical quantities , the number of places after decimal in the result  can never be more than least number of place after decimal in the quantities that are being multiplied .

Here numbers that are being multiplied are ,

1.12 , 1.25, and .83 , each containing two digits after decimal . So the product can not contain more than two digits after decimal . The principle behind it is that the result can not have more precision than the precision of  amount that are being multiplied.

so

1.12 x 1.25 x .83 = 1.162 to be rounded off to 1.16 .

The answer is 1.16.

A string of length L, fixed at both ends, is capable of vibrating at 309 Hz in its first harmonic. However, when a finger is pla
Scorpion4ik [409]

Answer:

 i = 0.3326 L

Explanation:

A fixed string at both ends presents a phenomenon of standing waves, two waves with the same frequency that are added together. The expression to describe these waves is

    2 L = n λ           n = 1, 2, 3…

The first harmonic or leather for n = 1

Wave speed is related to wavelength and frequency

     v = λ f

     λ = v / f

Let's replace in the first equation

    2 L = 1 (v / f₁)

For the shortest length L = L-l

   2 (L- l) = 1 (v / f₂)

These two equations form our equation system, let's eliminate v

    v = 2L f₁

    v = 2 (L-l) f₂

    2L f₁ = 2 (L-l) f₂

    L- l = L f₁ / f₂

    l = L - L f₁ / f₂

    l = L (1- f₁ / f₂)

.

Let's calculate

    l / L = (1- 309/463)

    i / L = 0.3326

What is Balanced and Unbalaced Forces ?
Sauron [17]






Hi Pupil Here is Your Answer ::




➡➡➡➡➡➡➡➡➡➡➡➡➡



Balanced Forces =》 If the resultant of several forces acting on a body is zero, the forces are said to be Balanced Forces.

Or

When two forces of equal magnitudes but acting in opposite direction on an object simultaneously then the object continuous in its state of rest all uniform motion in a straight line such forces acting on the object are known as Balanced Forces.



Unbalance Forces =》 If the resultant of several forces acting on a body is not zero, the forces are said to be Unbalanced Forces.

Or


When two forces of unequal magnitudes act in opposite direction on an object simultaneously then object moves in the direction of the force with larger magnitude forces. These force acting on the object are known as Unbalanced Forces.
