Consider a venturi with an inlet-to-throat area ratio of LaTeX: 1.501.50, mounted on the side of an airplane fuselage where the local air density is LaTeX: 1.225 mathrm {kg/m^3}1.225 k g m 3. A manometer is connected to the inlet and the throat; the height difference of the liquid is seen to be LaTeX: 12.5 mathrm {cm}12.5 c m. The manometer uses mercury, which has a density of LaTeX: 1.36 times10^4 mathrm {kg/m^3}1.36 × 10 4 k g / m 3. However, at this altitude gravity is only LaTeX: 95 % of the gravity at Earth's surface. What speed is the airplane flying at?

good for her? ? where is the question?

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

1/0.14nm = 10^10/1.4 a lot

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
