That is a series circuit because they are all in a row on the same path

The answer is Series.

I have taken the test, and that was the correct answer.

I hope this helps. :)

If this did not happen, what would be the approximate force on an eardrum of area 0.22 cm2 if a change in altitude of 1500 m tak

Complete Question

When you ascend or descend a great deal when driving in a car yours ears "pop," which means that the pressure behind the eardrum is being equalized to that outside. If this did not happen, what would be the approximate force on an eardrum of area .50 cm2 if a change in altitude of 950 m takes place?

Answer:

The value is $F = 0.60 \ N$

Explanation:

From the question we are told that

The area of the ear drum is $A = 0.5 \ cm^2 = 0.50 *10^{-4} \ m^2$

The change in altitude is $\Delta d = 950 \ m$

Generally the change in pressure is mathematically represented as

$\Delta P = \frac{F}{A}$

This can also be mathematically represented as

$\Delta P = \rho * g * \Delta d$

So

$\frac{F}{A} = \rho * g * \Delta d$

=> $F = \rho * g * \Delta d * A$

=> $F = \rho * g * \Delta d * A$

Here $\rho$ is the density of dry air with value $\rho = 1.29 \ kg /m^3$

So

$F = 1.29 * 9.8 * 950 * 0.50 *10^{-4}$

=> $F = 0.60 \ N$

why can we use P=VI in the question electric bulb base generator is rated 220 volts and 100W when it is operated on 110v what wi

MrRissso [65]

Answer:

Correct answer: P₂ = 25 W

Explanation:

Given: voltage V₁ = 220 V, power P₁ = 100 W, V₂ = 110 V, P₂ = ?

The formula for calculating power is:

P = V · I

We will include in the story and ohm's law:

I = V/R

We will replace the current in the expression for power

P = V · V/R = V²/R ⇒ R = V²/P

We will first calculate the electrical resistance of the bulb which is a constant in the electrical circuit

R = V₁²/P₁ = 220²/ 100 = 48,400 / 100 = 484 Ω

Power consumption of bulb connected to 110 V is:

P₂ = V₂²/R = 110²/484 = 12,100/484 = 25 W

P₂ = 25 W
