Step-by-step explanation:
0.09w + 1.8 = 0
0.09w = 0 - 1.8
0.09w = - 1.8
0.09w ÷ 0.09 = - 1.8/ 0.09
w = - 20
Fidn volume
V=hpir^2
d/2=r
1.4/2=0.7=r
height=3.5
V=3.5*3.14*0.7^2
V=5.3851
1.5 times t=5.3851
divide both sides by 1.5
t=3.59
round
t=4
4 minutes
Answer:

Step-by-step explanation:
We know (Ohm second law) that
where k inlcudes the rest of the parameters (material, lenght). In our situation we have k=
. The moment the diameter becomes 8mm R becomes
