Physics
1 answer:
valina [46]4 years ago

<u>Answer</u>:

Resolution in chromatography is a function of "selectivity, number of plates, and capacity factor".

<u>Explanation</u>:

Resolution is a measure of the separation of 2 peaks of different retention time t in a chromatography divided by the combined widths of the elution peaks.

The resolution is denoted as a numerical value, such as 0.3, 4.0, or 1.0

. Resolution not only  depend on column, but also on the flow-rate and  mobile phase composition, the rate of gradient and the composition and size of  peptides themselves.

R_{s}=\frac{1}{4} \times \frac{\alpha-1}{\alpha} \times \frac{k}{k+1} \times \sqrt{N_{t h}}

Where

R_s is the resolution factor.

\alpha is selectivity factor.

K is the retention factor  or the capacity factor.

N_{th}  theoretical plate number.

Un hombre parado en el techo de un edificio, tira una bola verticalmente hacia arriba con una velocidad de 12m/s, la bola llega
zmey [24]

Respuesta:

24m

Explicación:

Según la ecuación de movimiento

v = u + en

Dado

Velocidad final v = 12 m / s

velocidad inicial u = 0 m / s

tiempo t = 4s

Sustituir

12 = 0 + 4a

a = 12/4

a = 3 m / s²

Lo siguiente es obtener la distancia;

S = ut + 1 / 2at²

S = 0 (4) + 1/2 (3) (4) ²

S = 3 * 16/2

S = 48/2

S = 24 m

Por lo tanto, la distancia requerida es de 24 m.

A 68.0 kg diver falls from rest into a swimming pool from a height of 4.90 m. It takes 1.46 s for the diver to stop after enteri
Natali5045456 [20]

Answer:

456.4 N

Explanation:

From conservation of energy, the potential energy is converted to kinetic energy hence

mgh=½mv²

Making v the subject then

v=\sqrt {2gh}

Where g is acceleration due to gravity and h is height whike v is final velocity. Substituting 4.9m for h and 9.81 m/s² for g then

v=\sqrt {2\times 9.81\times 4.9}=9.80499872514015m/s\approx 9.8 m/s

Change in momentum equals to the impulse.

Impulse, I= Ft

Change in momentum, ∆p= m(v-u)

Ft=m(v-u) making F the subject of formula then

F=\frac {m(v-u)}{t}

Where F is force in Newton, t is time in seconds, m is mass of diver, v and u are the final and initial velocities respectively.

Substituting 68 kg for m, 9.8 m/s for v, 0 m/s for u since it is initially at rest and 1.46 s for t

F=\frac {68(9.8-0)}{1.46}=456.43835616438N\approx 456.4N
