A milk

Explanation:

A solution is a homogeneous mixture of solutes and solvents. The solute is the substance usually solid dissolved to make the solution.

The solute is usually present in small amount compared to the solvent.
A milk is solution of different components.
Most liquid milk are made up of powdered milk dissolved in water and sugar added to it.
All the constituent will now exist in a single phase as a liquid and be homogeneous.
They are homogeneous in the sense that all the parts are uniform.

Which of the following is an incorrect statement of one of newtons laws of motion?

weqwewe [10]

Explanation:

The newton's laws of motion are:

First law:

"A body will remain in its state of rest or of uniform motion along a path unless it is acted upon by an external force. ".

This is popularly called the law of inertia.

Second law:

"the acceleration of a body is produced by a net force that is inversely proportional to the mass of the body".

Third law:

"action and reaction forces are equal and opposite in direction".

Two converging lenses are separated by 27.0 cm. The focal length of each lens is 8.90 cm. An object is placed 33.0 cm to the lef

Ymorist [56]

Answer:

1/i + 1/o = 1/f thin lens equation

i = 33 * 8.9 / (33 - 8.9) = 12.2 cm to right of first lens

27 - 12.2 = 14.8 cm to left of second lens

i = 14.8 * 8.9 / (14.8 - 8.9) = 22,3 cm to right of second lens

You want to manufacture a guitar such that the instrument will be in tune when each of the strings are tightened to the same ten

charle [14.2K]

Answer:

0.000507 kg/m

Explanation:

L = Length of string

T = Tension

$\mu$ = Mass density of string

E denotes the E string

D denotes the D String

Frequency is given by

$f=\dfrac{1}{2L}\sqrt{\dfrac{T}{\mu}}$

$f\propto \sqrt{\dfrac{1}{\mu}}$

$\dfrac{f_D}{f_E}=\sqrt{\dfrac{\mu_E}{\mu_D}}\\\Rightarrow \mu_E=\dfrac{f_D^2}{f_E^2}\mu_D\\\Rightarrow \mu_E=\dfrac{146.83^2}{329.63^2}\times 0.00256\\\Rightarrow \mu_E=0.000507\ kg/m$

The mass density of the E string is 0.000507 kg/m
