WILL MARK BRAINLIEST. Look at the circuit below. What is the voltage between points C and D?

elena-s [515]

Since two identical bulbs are connected in this circuit in series combination

So here same current will flow into the circuit

So here we can say

$V = V_1 + V_2$

$V = 3 volts$

also we know that

$V_1 = iR_1$

$V_2 = iR_2$

also it is given that bulbs are identical so we have

$V_1 = V_2$

as we have

$R_1 = R_2$

so now we can say

$V = 2V_{CD}$

$3 = 2V_{CD}$

$V_{CD} = 1.5 Volts$

so here voltage across C and D is 1.5 volts

A 68 kg hiker walks at 5.0 km/h up a 3% slope. The indicated incline is the ratio of the vertical distance and the horizontal di

sertanlavr [38]

Answer:

$P = 27.8 Watt$

Explanation:

As we know that the slope of the inclination is 3%

so we can say that

$tan\theta = 0.03$

since it is very small so here we can take approximation as

$tan\theta = sin\theta = 0.03$

so we need to find the metabolic power which is given as

$P = F. v$

so here we have

$F = mg sin\theta$

$v = 5 km/h = 1.39 m/s$

now we have

$P = (68)(9.81)(0.03)(1.39)$

$P = 27.8 Watt$

A transformer is to be used to provide power for a computer disk drive that needs 6.4 V (rms) instead of the 120 V (rms) from th

Amanda [17]

Answer:

The current in the primary is 0.026 A

Explanation:

Using the formula

I1 = (V1/V2)*I2

we have

I1 = (6.4/120)*0.500

I1 = 0.026 A
