Answer:
Explanation:
The law of conservation of angular momentum states that angular momentum remains constant when there is no external moment or forces applied to the system. Let assume that star can be modelled as an sphere, then:
The final angular speed is:
Please help The position of masses 4kg, 6kg, 7kg, 10kg, 2kg, and 12kg are (-1,1), (4,2), (-3,-2), (5,-4), (-2,4) and (3,-5) resp

Answer:
(1.9756, -2.1951)
Explanation:
The center of mass equation is: = , where m represents the masses and x represents the position.
In order to find the coordinates of the center of mass, we need to use this equation for both the x-values and the y-values.
<u>x-values:</u>
<u /> = = = = = 1.9756
<u>y-values:</u>
<u /> = = = = = -2.1951
<u>center of mass:</u>
(1.9756, -2.1951)
Hello there,

Answer:
Can't tell if this is a real question or not but....
Reality shifting is based around this idea, but instead of letting it happen freely, the most precise details of your experience are planned by you! It's like incorporating a daydream into your subconscious. Reality shifting is a complex process, but anyone is able to do it.
Explanation:
The amount of heat energy that must still be removed by the cooling system is 1300 kJ.
<h3>Conservation energy</h3>
The total energy before and after a transformation must be equal.
Based on this principle, the heat energy that must still be removed by the cooling system is calculated as follows;
Input heat energy = out put heat energy
E = h + w
2000 kJ = h + 700 kJ
1300 kJ = h
Thus, the amount of heat energy that must still be removed by the cooling system is 1300 kJ.
