Answer:
Say the full question I can't understand what it is
Answer: length of B =4.00
Explanation:
for the vectors A and B and the angle between them as x.
Magnitude of the sum of A and B is given as = √(A²+B²+2ABcosx
where
Magnitude of A = 3.00
Magnitude of the sum of A and B is 5.00
5.00=√(A²+B²+2ABcos90°
5.00= √3² +b² +0
5²= 3² +b²
25=9+b²
b²= 25-9
b² = 16
b= √16
b= 4
Answer:
electricity is the answer
Explanation:
because as you can see beaker 2 has higher temperature. As volume is directly propotional
to temperature. So the the water molecules has
more energy so that's why levels are different.
