What is the relationship between phase and density

1 answer:

7 0

The answer is "a phase is a wave and density is what gives the wave its volume giving it its wavelength." Phases have different meanings for example phases of a moon and such but in this case phases are parts of mechanical waves that are closely related to each other meaning coming from the same object. So, with density is volume and because of volume it gives the wave its wavelength which is a phase. (when two waves are closely related)

Hope this helps!

two boys searching for buried treasure are standing underneath the same tree. One boy walks 18m east and then 18m north. The oth

spin [16.1K]

To solve this problem we must simply have the knowledge of scalar product.

Let's define the route of the two people as A and B. Then the first route, the A, would be given by,

We will take the Cartesian plane system as our reference system in which the north is equivalent to the positive sense of the Y axis. And the positive sense of the X will be equivalent to the east.

$A = 18\hat{i}+18\hat{j}$

$B = -16\hat{i} +11\hat{j}$

Making the scalar product we have to,

$A*B = (18\hat{i}+18\hat{j})*(-16\hat{i} +11\hat{j})$

$A*B = (18*16)(18*11)$

$A*B = -288+198$

$A*B = -90$

Therefore the product of their net displacements from the ree is -90.

How much work must be done on a 24-kg shopping cart to increase its speed

lisov135 [29]

Answer:

The work done by the shopping cart is 180 J

Explanation:

We have,

Mass of a shopping cart is 24 kg

Initial speed of cart is 1 m/s

Final speed of a cart is 4 m/s

It is required to find the work done by the shopping cart. The work done by an object is also equal to the change in its kinetic energy as per work -energy theorem. It means,

$W=\dfrac{1}{2}m(v^2-u^2)$
