Since Allura Red is red in color, why did we choose to use monitor the wavelength of 470 nm? does allura red transmit or absorb

red light ?

Answer:

Wavelenght of light in the range of 470nm is that of blue colourand Allura red absorbs this blue light and reflects the red light

Then we can say Allura red absorbs all light colours but reflect red

An elementary particle of mass m completely absorbs a photon, after which its mass is 1.01m. (a) what was the energy of the inco

sdas [7]

A.) We use the famous equation proposed by Albert Einstein written below:

E = Δmc²
where
E is the energy of the photon
Δm is the mass defect, or the difference of the mass before and after the reaction
c is the speed of light equal to 3×10⁸ m/s

Substituting the value:

E = (1.01m - m)*(3×10⁸ m/s) = 0.01mc² = 3×10⁶ Joules

b) The actual energy may be even greater than 3×10⁶ Joules because some of the energy may have been dissipated. Not all of the energy will be absorbed by the photon. Some energy would be dissipated to the surroundings.

The frequency of the applied RF signal used to excite spins is directly proportional to the magnitude of the static magnetic fie

Anni [7]

Answer:

The inverse frequency is $\dfrac{3}{80}\ s$

Explanation:

Given that,

Magnetic field = 20 T

Proportionality constant = 5 Hz/T

Change in magnetic field = 3 T

We know that,

$B=\dfrac{K}{\dfrac{1}{\omega}}$

We need to calculate the inverse frequency

Using formula of frequency

$\Delta(\dfrac{1}{\omega})=\dfrac{\Delta B}{k\times(\dfrac{1}{\omega^2})}$

$\Delta(\dfrac{1}{\omega})=\dfrac{k\times\Delta B}{B^2}$

Put the value into the formula

$\Delta(\dfrac{1}{\omega})=\dfrac{3\times5}{(20)^2}$

$\Delta(\dfrac{1}{\omega})=\dfrac{3}{80}\ s$

Hence, The inverse frequency is $\dfrac{3}{80}\ s$

A solenoid of length 18 cm consists of closely spaced coils of wire wrapped tightly around a wooden core. The magnetic field str

Kisachek [45]

Answer:

$B_2 = 1.71 mT$

Explanation:

As we know that the magnetic field near the center of solenoid is given as

$B = \frac{\mu_0 N i}{L}$

now we know that initially the length of the solenoid is L = 18 cm and N number of turns are wounded on it

So the magnetic field at the center of the solenoid is 2 mT

now we pulled the coils apart and the length of solenoid is increased as L = 21 cm

so we have

$\frac{B_1}{B_2} = \frac{L_2}{L_1}$

now plug in all values in it

$\frac{2.0 mT}{B_2} = \frac{21}{18}$

$B_2 = 1.71 mT$
