You undistribute like
ab+ac=a(b+c) so
2pir^2+2pirh=(2pir)(r)+(2pir)(h)=2pir(r+h)
Answer:
3.46 or ..
Step-by-step explanation:
because you use sin(60) = 3/u
The answer to number 3 is (0,-2)
Step-by-step explanation:
we have 8 equally "heavy" batches.
one weighs 3.9 × 10^-10 g
so, the total sample then weighed
8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g
Answer:
Charges are both negative and positive as such negative charges are drawn to positive charges and the same with positive being drawn to negative
this can be explained because the human body has natural medals in that attract negative and positive charges just like metal.
