bija089 [108]

The complete observation about adding bulb 3 is the brightness of the bulbs has to do with power which considers both the voltage and the current: less voltage x less current = dimmer bulbs.  In circuit A, the voltage is divided across the resistors and the current decreases as resistance increases.  In circuit B, the voltage is the same in each parallel section of the circuit and the current through that section of the circuit only depends on the resistor in that section.

<h3>What is power of the circuit?</h3>

The power of the bulb or any resistor is equal to the product of voltage and  current flowing through it.

P = VI

Circuit A has bulbs in series while the circuit B has bulbs in parallel.

When bulb 3 added to circuit A,  the brightness of all the bulbs dimmed but when bulb 3 (R3) added to circuit B, nothing changed in the brightness of the bulb.

The brightness is depended on the power of the circuit. When both the voltage and current are less, the bulb will be dimmed. In circuit A, series resistors divide the voltage across them. In circuit B, voltage is equal for all the resistors.

Thus, the last option is correct.

Express 75−−√ in the form ab√.
Nana76 [90]
We can write 75 = 25 x 3
and √75 = <span>√ (25 x 3) = </span>√25 x <span>√3 
Now we know that square root of 25 is 5 a 5x5 = 25 
so we can express this in the form of 5</span><span>√3.</span>

Den pushes a desk 400 cm across the floor he exerts a force of 10 no for 8 so to move the desk what is the power in put
Licemer1 [7]
You have to convert 400 cm into meters.
I'm assuming you mean a force of 10 Newtons in 8 seconds.
P= w/t
w=Fd
w= 10 x 4 = 40
P= 40 / 8 = 5
5 is your answer.
