What would be the result of voltage while joining 2 or more different voltages of batteries with parallel ? and explain me what

cupoosta [38]

That's not a good idea. You don't want to connect batteries with different voltages in parallel. What happens is large currents among the batteries themselves, and some of the batteries quickly die.

When the batteries are connected in SERIES, they behave as a single battery whose voltage is the sum of their individual voltages.

. You are making a frame of uniform width for a picture that is to be displayed at the local museum. The picture is 4 feet tall

Answer:

1 feet

Explanation:

Frame width = x

The length of the frame will be

$L=4+x+x$ (bottom and top that is why x is added twice)

$\\\Rightarrow L=4+2x$

The width of the frame will be

$W=3+x+x\\\Rightarrow W=3+2x$

Area is given by

$A=LW\\\Rightarrow 30=(4+2x)(3+2x)\\\Rightarrow 30=12+14x+4x^2\\\Rightarrow 4x^+14x-18=0$

Solving the above equation we get

$x=\frac{-14+\sqrt{14^2-4\cdot \:4\left(-18\right)}}{2\cdot \:4}, \frac{-14-\sqrt{14^2-4\cdot \:4\left(-18\right)}}{2\cdot \:4}\\\Rightarrow x=1, -\frac{9}{2}$
