The visible radiation produced by new stars within a molecular cloud get absorbed by dust grains and heats up the cloud
A molecular cloud is an interstellar cloud of gas and dust in which molecules can form, the most common of which is hydrogen .
The formation of stars occurs exclusively within molecular clouds because of their low temperatures and high densities, because the gravitational force acting to collapse the cloud must exceed the internal pressures that are acting "outward" to prevent a collapse.
Visible radiation are absorbed by dust grains and heats up the cloud as it cannot penetrate through the cloud instead get absorbed by the cloud . Newly formed stars are visible nearby, their images reddened by blue light which got scattered by the pervasive dust.

It's the Answer to your Question
What results do we communicate?
The formula for working out kinetic energy is
=122
KE = kinetic energy
m = mass of a body
v = velocity of a body
kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
For the first one I think :
Answer:
KE = 330750 J
I’m not sure about the second one- sorry
The third is
Answer:
KE = 41454 J
Hope it helps and it is correct, sorry if it isn’t !
Answer:c=0.213 J/g/K
Explanation:
Given
sample mass
initial temperature of mineral
mass of water
Water initial temperature
Heat capacity of calorimeter =15.3 J/k
Final Temperature is 24.8
let c be the specific heat of mineral
Heat released by mineral sample=heat absorbed by calorimeter and water
