A change in ________ results in _______

We divide the electromagnetic spectrum into six major categories of light, listed below. Rank these forms of light from left to

makkiz [27]

electromagnetic spectrum is consisting of many frequency range which is from gamma rays to radio waves

they are of various wavelength and different energy levels

minimum wavelength will occurs at Gamma rays

and maximum wavelength at Radio waves

the list of increasing order of wavelength is as following

Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves

so least to maximum order is

1. Gamma rays

2. X rays

3 Ultraviolet

4 Visible light

5 Infrared waves

6 Radio waves

How do you know that forces are balanced when static friction acts on an object?

lyudmila [28]

By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:
$\sum F = ma$

So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).

During typical urination, a man releases about 400 mL of urine in about 30 seconds through the urethra, which we can model as a

gregori [183]

Answer:

Explanation:

Given:

volume of urine discharged, $V=400~mL=0.4~L=4\times 10^{-4}~m^3$

time taken for the discharge, $t=30~s$

diameter of cylindrical urethra, $d=4\times10^{-3}~m$

length of cylindrical urethra, $l=0.2~m$

density of urine, $\rho=1000~kg/m^3$

a)

we have volume flow rate Q:

$Q=A.v$ & $Q=\frac{V}{t}$

where:

$A=$ cross-sectional area of urethra

$v=$ velocity of flow

$A.v=\frac{V}{t}$

$\frac{\pi d^2}{4}\times v=\frac{4\times 10^{-4}}{30}$

$v=\frac{4\times4\times 10^{-4}}{30\times \pi (4\times 10^{-3})^2}$

$v=1.06~m/s$

b)

The pressure required when the fluid is released at the same height as the bladder and that the fluid is at rest in the bladder:

$P=\rho.g.l$

$P=1000\times 9.8\times 0.2$

$P=1960~Pa$

How will you know which dye diffuses the most quickly?

k0ka [10]

Answer:

If there is a large difference between the concentration of one fluid and the concentration of the other, then the particles will diffuse faster. In the experiment, the dye particles in the food coloring are very concentrated.
