Answer:
Ratio of series current to parallel
= 1 : 8
Explanation:
Total resistance Rt
For series, Rt = 2+2+2+2 = 4ohms
For parallel, 1/Rt = 1/2 + 1/2 + 1/2 + 1/2
1/Rt = 4/2, Rt = 2/4 ohms.
If we use a 1V battery, then,
I = V/Rt
I = 1/4 = 0.25 ampere for series arrangement.
I = 1/0.5 = 2 ohms.
Ratio of current of series to parallel = 0.25 : 2
The ratio of electric current in series and in parallel connection is 0.0625
Here we have for the series resistors
∑R = R₁ + R₂ + R₃ + R₄ = 8 Ω
The current is gotten from
V = IR
I = V/R = V/8 Ω
For the parallel connected resistors we have
Which gives
Therefore,
From which,
= V/0.5 Ω
The ratio between the series and parallel connection electric current is therefore,
.
Below is an attachment containing the solution.
Natural selection is a mechanism, or cause, of evolution.
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
To find Depth D of lake we must need to find the time taken to hit the water.So we use equation of simple motion as:
Δx=vit+(1/2)at²
As we have find the time taken now we need to find the final velocity vf from below equation as
So the depth of lake is given by:
first we need to find total time as
t=3.0-1.01 =1.99 s
