Gases that are very good at absorbing long wave photons of infrared light

Explanation:

Green house gases examples are Carbon monoxide, nitric oxide etc.
These gases absorb long wave photons of infrared light of sun's rays
They melts the glaciers and increase the sea level .

If you were to separate all of the electrons and protons in 1.00 g (0.001 kg) of matter, you’d have about 96,000 C of positive c

Kryger [21]

Answer:

The attractive force between them is $1.296 \times 10^{18}$ N

Explanation:

Given:

Charge $q = 96000$ C

Distance between two charges $r = 8$ m

According to the coulomb's law,

$F = \frac{kq^{2} }{r^{2} }$

Where $k = 9 \times 10^{9}$ = force constant.

$F = \frac{9 \times 10^{9} \times (96000)^{2} }{8^{2} }$

$F = 1.296 \times 10^{18}$ N

Therefore, the attractive force between them is $1.296 \times 10^{18}$ N

An ideal gas at 25.8°C and a pressure 1.20 x 10^5 Pa is in a container having a volume of 1.00 L. (a) Determine the number of mo

vesna_86 [32]

Answer:

a) 0.0483 mol

b) 232 °C

Explanation:

Ideal gas law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is universal gas constant,

and T is absolute temperature.

a) Given:

P = 1.20×10⁵ Pa

V = 1.00 L = 1.00×10⁻³ m³

T = 25.8 °C = 298.95 K

PV = nRT

(1.20×10⁵ Pa) (1.00×10⁻³ m³) = n (8.314 m³ Pa / mol / K) (298.95 K)

n = 0.0483 mol

b) Given:

P = 1.013×10⁵ Pa

V = 2.00 L = 2.00×10⁻³ m³

n = 0.0483 mol

PV = nRT

(1.013×10⁵ Pa) (2.00×10⁻³ m³) = (0.0483 mol) (8.314 m³ Pa / mol / K) T

T = 505.73 K

T = 232 °C

At which point is the velocity the greatest?

zhuklara [117]

Answer:

a) The velocity is maximum at B.

b) The velocity is 0 at C and A.

c) The acceleration will be 0 at B

d) The acceleration is maximum at C and A.

Explanation:

In the attached image, we can see two sketches the first one is based on the principle os energy conservation and we can appreciate easily when the velocity is the greatest and when it will be 0.

In points A and C we have the maximum potential energy because the pendulum is at the highest elevation with respect to the reference point. And when the pendulum is in point B all the potential energy had been transformed into kinetic energy and therefore we will have the maximum velocity at this point.

For the acceleration analysis, we see the second sketch, this one is showing a free body diagram of the pendulum when it is forming a theta angle with respect to the vertical plane. And applying Newton's second law and contemplating the forces that are acting over the pendulum we have the equation showed in the image.

This equation shows that the acceleration which has the same direction as the velocity depends on the sin(theta) and we know that the equation will be zero (0) when the angle theta is 0. It means the acceleration will be 0 at point B. And maximum at points C and A.
