How do atmospheric pressure zones and ocean currents affect Earth's energy balance?

A converging lens and a diverging lens, separated by a distance of 30.0 cm, are used in combination. The converging lens has a focal length of 15.0 cm. The diverging lens is of unknown focal length. AN object is placed 20.0 cm in front of the converging lens; the final image is virtual and is formed 12.0 before the diverging lens. What is the focal length of the diverging lens?

A 1.00 mW helium-neon laser emits a visible laser beam with a wavelength of 633 nm. How many photons are emitted per second?

An object is located 16.0 cm in front of a converging lens with focal length 12.0 cm. To the right of the converging lens, separated by a distance of 20.0 cm, is a diverging lens of focal length-10.0 cm. Find the location of the final image by ray tracing and verify using the lens equations.

Why are coal, oil, and natural gas known as fossil fuels? F. They are nonrenewable sources of energy. G. They are generally found in deposits where fossils are found. H. They have been used as energy sources since prehistoric times. I. They were formed by the decomposition of ancient plants and animals.

In a double-slit experiment, light rays from the two slits that reach the second maximum on one side of the central maximum travel distances that differ by (a) $2 \lambda$, (b) $\lambda$, (c) $\lambda / 2$, (d) $\lambda / 4$

Decide which way an increase in pressure will shift the following equilibrium system involving ethane, $\mathrm{C}_{2} \mathrm{H}_{6}$, oxygen, $\mathrm{O}_{2}$, water, $\mathrm{H}_{2} \mathrm{O}$, and carbon dioxide, $\mathrm{CO}_{2}$.

$$2 \mathrm{C}_{2} \mathrm{H}_{6}(\mathrm{gas})+7 \mathrm{O}_{2}(\mathrm{gas}) \rightleftarrows 6 \mathrm{H}_{2} \mathrm{O}(\text { liquid })+4 \mathrm{CO}_{2}(\mathrm{gas})$$

Give the molecular formula of a hydrocarbon containing five carbon atoms that is an alkane,

What causes chromatic aberration? (a) Light is an electromagnetic wave and has intrinsic diffraction properties. (b) Different wavelengths of light give different angles of refraction at the lens-air interface. {c) The coefficient of reflection is different for light of different wavelengths. (d) The outer edges of the lens produce a focus at a different point from that formed by the central portion of the lens. (e) The absorption of light in the glass varies with wavelength.
