Why cant people with aids foght out the infection?

2 answers:

6 0

Because aids is a power disease, u can get it from anything but commonly its through sexual intercourse or oral and most people who get it CANT fight it because it has already reached their blood stream with the disease of aids. Aids CANT be cured purely but can be TREATED through special procedures depending on HOW u got aids in the first place. It can even be kissing another person who may be sick or already has aids and just transferred it to u.

Hope this helps.

The resistance of a wire depends upon the material's resistivity and the length and cross‑sectional area of the wire. What will

andriy [413]

Answer:

R' = 4R

The resistance will become 4 times the initial value.

Explanation:

The resistance of a wire at room temperature, is given by the following formula:

R = ρL/A ----------- equation 1

where,

R = Resistance of wire

ρ = resistivity of the material

L = Length of wire

A = Cross-sectional area of wire

Now, if the length (L) is multiplied by 4, then resistance will become:

R' = ρ(4L)/A

R' = 4 (ρL/A)

using equation 1:

R' = 4R

The resistance will become 4 times the initial value.

How many justified by Bohr model?

Dominik [7]

X-ray formation

Energy difference in the first ionization of the same group of elements

Differential linear emission spectra of different elements

Explanation:

The formation of x-ray, energy difference in the first ionization of the same group of elements and differential linear emission spectra of different elements can be justified by the Bohr model of the atom.

According to Neil Bohr, in an atom, the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
Bohr's model explained the discrete lines in atomic spectrum of different elements.
Due to excitation of electrons, some rays are given off. Some of these are energetic like x-rays.
The energy difference between the first ionization of the same group of elements is a proof that electrons are in specific spherical orbits.
The higher the energy the level, the ease at which electrons can be removed and the lower the ionization energy.

What is the slit spacing of a diffraction necessary for a 600 nm light to have a first order principal maximum at 25.0°?

Sauron [17]

Explanation:

Given that,

Wavelength of light, $\lambda=600\ nm=6\times 10^{-7}\ m$

Angle, $\theta=25^{\circ}$

We need to find the slit spacing for diffraction. For a diffraction, the first order principal maximum is given by :

$d\sin\theta=n\lambda$

n is 1 here

d is slit spacing

$d=\dfrac{\lambda}{\sin\theta}\\\\d=\dfrac{6\times 10^{-7}}{\sin(25)}\\\\d=1.41\times 10^{-6}\ m\\\\d=1.41\ \mu m$

So, the slit spacing is $1.41\ \mu m$ .
