What does Newton’s law of universal gravitation say about the distance between objects? s=been 3 hours still waiting...

Chemistry

Answer:

Gravitational Force is <u><em>inversely</em></u><em> proportional  to the </em><u><em>square of distance </em></u><em>between the objects </em>

F\alpha \frac{1}{d^{2}}

Explanation:

This means if distance is tripled(3 times), then Force reduced to 1/9(square of distance )

If d = 3 ,

F\alpha \frac{1}{3^{2}}

F\alpha \frac{1}{9}

Then , F reduced to 1/9

How do transmittance, absorbance, and molar absorptivity differ? Which one is proportional to concentration?
Komok [63]

Answer:

The transmittance is the amount of energy that a body goes through in a certain amount of time without being absorbed and the absorbance is the amount of light that is absorbed by a solution.

There is no difference between absorptivity and molar absorptivity because the two terms express the same idea, because molar absorptivity is the absorbance of a solution per unit path length and concentration, so that the absorbance is proportional to concentration.

How many moles of a gas would occupy 11.4 L at 273K and 2.00 atm?
bagirrra123 [75]

Answer:

1.02mol

Explanation:

Using the general gas equation below;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question,

P = 2.0 atm

V = 11.4L

T = 273K

n = ?

Using PV = nRT

n = PV/RT

n = 2 × 11.4/ 0.0821 × 273

n = 22.8/22.41

n = 1.017

n = 1.02mol
