Answer:

We can't observe what's inside there, because no light – no information of any kind – can escape a black hole. But astrophysical theories suggest that, at the core of a black hole, all the black hole's mass is concentrated into a tiny point of infinite density. This point is known as a singularity.11 Jan 2020

What is the most highly populated rotational level of Cl2 (i) 25deg C and (ii) 100 deg C? Take B=0.244cm-1.This question should

horsena [70]

Answer:

$J_{m} = 20$

$J_{m} = 22.5$

Explanation:

From the question we are told that

The first temperatures is $T_1 = 25^oC = 25 +273 =298 \ K$

The second temperature is $T_2 = 100^oC = 100 +273 = 373 \ K$

Generally the equation for the most highly populated rotational energy level is mathematically represented as

$J_{m} = [ \frac{RT}{2B}] ^{\frac{1}{2} } - \frac{1}{2}$

Here R is the gas constant with value $R =8.314 \ J\cdot K^{-1} \cdot mol^{-1}$

Also

B is given as $B=\ 0.244 \ cm^{-1}$

Generally the energy require per mole to move 1 cm is 12 J /mole

So $0.244 \ cm^{-1}$ will require x J/mole

$x = 0.244 * 12$

=> $x = 2.928 \ J/mol$

So at the first temperature

$J_{m} = [ \frac{8.314 * 298 }{2* 2.928 }] ^{\frac{1}{2} } - 0.5$

=> $J_{m} = 20$

So at the second temperature

$J_{m} = [ \frac{8.314 * 373 }{2* 2.928 }] ^{\frac{1}{2} } - 0.5$

=> $J_{m} = 22.5$

3. Winds always blow from high to low pressure. How do landmasses impact the movement of air and water?

They stop all movement of both air and water.

They speed up the air and water and allow it to pass though.

They change the direction and slow them down.

think this is it

They slow down the air but speed up the water.

What are the various forms of energy?

Fantom [35]

Science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object.
