Answer:
I=P/U=6/12=0.5(A)
Explanation: P=UI ( CÔNG SUẤT = HIỆU ĐIỆN THẾ NHÂN VỚI C Đ D Đ)
distance is the length of his trip so 15( 3+4+8)
displacement is how far he is from his original point ( -5)( -4^2 + 3^2 = 5^2) he was displaced 5 meters from his start position
Answer:
Density does not change when you divide the cube, due to the principle of mass conservation. The density given in this case by 3 
, will remain the same.
The only way for it to change, will be if you compressed the block, so now the same mass will be compressed in less volume, or you add heat to the system.

Ti = 92.8 oC = 92.8 + 273 = 365.8
T2 = 0.4 oC = 0.4 + 273 = 273.4
Vi = 1.54 mL
Vf = ?????
Formula
======
Vi/Ti = Vf / Tf
1.54 / 365.8 = Vf / 273.4
Calculations
=========
1.54 * 273.4 / 355.8 = Vf
vf = 1.15 mL
Comment
=======
if your teacher is concerned about sig digs, the answer is 1 mL. I'm not sure how to show that it is 1 sig dig. You can ask about this.
