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)
A substance undergoing a physical change will still weigh the same even after the change. This is in accordance to the law of conservation of mass which states that mass is neither created nor destroyed. so an 8 g substance remains of the same weight even after undergoing a physical change.
Biology involves living systems that interact with each other and with the environment. Like chemical processes, biological processes involve the transfer or sharing of electrons among atoms and the interaction of atoms and molecules with electromagnetic energy.
Answer:
A) 1.9m/s
Explanation:
Use the equation v=d/t
The time is 10 seconds. The distance is more complicated because it’s a circle so u use the equation for circumference C=2•pi•r. So you just do the circumference over time and get the answer. Hope this helps
