How can you remember meiosis 1 and meiosis 2

Marianna [84]

Answer:

Once you know the differences between meiosis 1 and 2, you will remember it easier.

Explanation:

Meiosis 1 starts with 1 diploid cell Meiosis 2 starts with 2 haploid cells,

each with a homologous pair

Meiosis 1 results in 2 daughter cells Meiosis 2 results in 4

What is the threshold velocity vthreshold(ethanol) for creating Cherenkov light from a charged particle as it travels through et

AnnZ [28]

Explanation:

The velocity of light in a medium of refractive index $n[tex] is given by,
[tex]v=\frac{c}{n}$

$v \text { is the velocity of light in the medium }$

$c \text { is speed of light in vacuum }$

The exact value of speed of light in vacuum is $299792458 \mathrm{m} / \mathrm{s}$ .

For Cherenkov radiation to be emitted, the velocity of the charged particle traversing the medium must be greater than this velocity. Thus, the threshold velocity of for creating Cherenkov radiation is,

$v_{\text {Cherenkov }} \geq \frac{c}{n}$

$v_{\text {threshod }}=\frac{c}{n}$

For water $n=1.33,[tex] thus the threshold velocity for producing Cherenkov radiation in water is,
[tex]v_{\text {threatold }(\text { water })} &=\frac{299792458 \mathrm{m} / \mathrm{s}}{1.33}$

$=225407863 \mathrm{m} / \mathrm{s}$

$=2.254 \times 10^{8} \mathrm{m} / \mathrm{s}$

For ethanol $n=1.36[tex], thus the threshold velocity for producing Cherenkov radiation in water is,
[tex]v_{\text {threstold }( \text { ettanol) } } &=\frac{299792458 \mathrm{m} / \mathrm{s}}{1.36}$

$=220435630 \mathrm{m} / \mathrm{s}$

$=2.204 \times 10^{8} \mathrm{m} / \mathrm{s}$

The Pilot of a plane measures an air velocity of 165Km/h south relative to the plane. An observer on

AVprozaik [17]

The speed obtained by the pilot is not accurate since it is measuring the rate of travel in the wind, true velocity is that compared to the ground. Therefore the speed of the wind is:

v wind = 165 - 145

v wind = 20 km/h<span>

<span>Therefore the wind velocity = 20 km/h against the plane.</span></span>
