a) Equivalent resistance is 143 Ω</h2><h2>
b) Potential difference is 71.5 V</h2>
Explanation:
When resistors are connected in series, effective resistance is given by
Here
R₁ = 21Ω
R₂ = 58Ω
R₃ = 64Ω
a)
Equivalent resistance is 143 Ω
b) We know
Potential difference = Current x Resistance
V = IR
I = 0.5 A
R = 143Ω
Substituting
V = 0.5 x 143 = 71.5 V
Potential difference is 71.5 V
Answer:
7.06MN
Explanation:
length = 60m
Width = 10m
Height = 12 m
Let Fb = Force buoyant
Fb = pgV = mg
p(density) = rho
The density of water in this case = 1000
g = 9.8 m/s
Volume = lenght*width*height
= 60*10*12
= 7200m^3
So we have
(1000 * 9.8 * 7200) = mg
= 70560000
7.06 MN
B) equal in magnitude but opposite direction
