Answer:

(a). 2

(b). 1/3

(c). 11.11

Explanation:

(a).  k= (t₍s₎-t₍o₎)/t₍o₎...............(1)

where k= retention factor,

t₍o₎=solvent time, t₍s₎= solute time.

Given t₍s₎=9.0 Minutes, t₍o₎=3.0 minutes.

∴ k= (9-3)/3

  k= 2.

(b). the fraction of time the solute spend in the mobile phase in the column is the ratio of the solvent time to the solute time. = t₍o₎/t₍s₎..........(2)

= 3/9

=1/3.

(c). K=k(Vm/Vs)................(3)

where K= partition coefficient, k= retention factor, Vm=volume of mobile phase, Vs= volume of stationary phase.

∴K = k(Vm/Vs)

k=2, and Vs=0.18Vm.

∴K = 2(Vm/0.18vm)

⇒K = 2/0.18

∴K=11.11

A mass of 790 kg is hanging from a crane (neglect the mass of the cable and the hook). While the mass is being lowered, it is sp
Margarita [4]

Answer:

Explanation:

Given

mass of object hanging from crane is m=790\ kg

mass is speeding up with a=2.7\ m/s^2

If T is the Tension in the cable then

mg-T=ma

T=mg-ma

T=m(g-a)

T=790\times (9.8-2.7)

T=790\times 7.1

T=5609\ N

A spaceship accelerates uniformly for 1220km how much time is needed for the spaceship to increase its speed from 11.1km/s to 11
snow_lady [41]

The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s is 107 s

<h3>Data obtained from the question</h3>

The following data were obtained from the question given above:

  • Initial velocity (u) = 11.1 Km/s
  • Final velocity (v) = 11.7 Km/s
  • Distance (s) = 1220 Km
  • Time (t) =?

<h3>How to determine the time</h3>

The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s can be obtained as illustrated below:

s = (u + v)t / 2

Cross multiply

(u + v)t = 2s

Divide both sides by (u + v)

t = 2s / (u + v)t

t = (2 × 1220) / (11.1 + 11.7)

t = 2440 / 22.8

t = 107 s

Thus, the time taken for the spaceship to change its speed is 107 s

Alex_Xolod [135]
<span>The four main stages of the sun's predicted evolution in order from beginning to end are as follows: main sequence (when a star's core is fusing hydrogen); red giant (larger star, where no hydrogen remains in the core); planetary nebula (surrounds an aging star; ring shaped nebula made of gas); and white dwarf (smaller star that tends to be as large as an actual planet; after nebula state).</span>

A meterologist made these observations one day:
Vinvika [58]

Answer:

They transfered more energy in the morning.

Explanation:

This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with  the waves. They have more energy, so they can crash aganst the shore more!
