Suppose that we repeat the experiment, except that we place the sodium flame in a strong, localized electric field. The field ch

anges the energy levels of the sodium atom, but it does not affect the sodium in the lamp or the photons it produces. The shadow cast by the sodium flame when illuminated by the sodium lamp should Stay the same, get darker, or lighter?

Answer:

Lighter

Explanation:

In practice, the lamp is powered by an AC voltage source which is connected in series with an inductive ballast in order to supply an approximately constant current to the lamp, rather than a constant voltage. This helps to provide a stable operation. The ballast is usually inductive rather than simply being resistive to maximize resistive losses.

As this lamp current tending to zero-current point and shadow cast by the sodium flame becoming lighter.

Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). The
chubhunter [2.5K]

Answer:

B=2.025\times 10^{11}\ Pa

Explanation:

It is given that,

Speed of P- waves, v = 9 km/s = 9000 m/s

The density of rock is about 2500\ kg/m^3

We need to find the average bulk modulus of Earth's crust. Let it is given by B. So,

v=\sqrt{\dfrac{B}{d}} \\\\B=v^2d\\\\B=(9000)^2\times 2500\\\\B=2.025\times 10^{11}\ Pa

So, the bulk modulus of the Earth's crust is 2.025\times 10^{11}\ Pa.

You paddle a conoe with a force of 325 N. You and the canoe have a combined mass of 250 kg. What is the acceleration of the cano
Brums [2.3K]

f = ma

Rearranging it, we get;

a =  \frac{f}{m}
Where a is the acceleration, f is the force, and m is the mass

a =  \frac{325}{250}
a = 1.3 \frac{m}{ {s}^{2} }
