A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvat
Stolb23 [73]

Answer: f=150cm in water and f=60cm in air.

Explanation: Focal length is a measurement of how strong light is converged or diverged by a system. To find the variable, it can be used the formula:

\frac{1}{f} = (nglass - ni)(\frac{1}{R1} - \frac{1}{R2}).

nglass is the index of refraction of the glass;

ni is the index of refraction of the medium you want, water in this case;

R1 is the curvature through which light enters the lens;

R2 is the curvature of the surface which it exits the lens;

Substituting and calculating for water (nwater = 1.3):

\frac{1}{f} = (1.5 - 1.3)(\frac{1}{10} - \frac{1}{15})

\frac{1}{f} = 0.2(\frac{1}{30})

f = \frac{30}{0.2} = 150

For air (nair = 1):

\frac{1}{f} = (1.5 - 1)(\frac{1}{10} - \frac{1}{15})

f = \frac{30}{0.5} = 60

In water, the focal length of the lens is f = 150cm.

In air, f = 60cm.

How are the surface of Mercury and Mars similar to the surface of the Earth?
scZoUnD [109]

Answer:

The terrestrial planets all have rocky surfaces that feature mountains, plains, valleys and other formations. ... Mars has very low atmospheric pressure, and Mercury has almost none, so craters are more common on these planets.

A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with ba
pentagon [3]

The change of state as depicted by the model is condensation.

<h3>What is Condensation?</h3>

The process by which the water vapors get converted into liquid droplets to get settled on a cold surface is known as condensation.

As per the given problem, the cylinder in the left has the balls evenly spaced throughout and the right cylinder has the balls in the form of layers at its bottom.

So, this clearly reflects that the comparing both the balls in both cylinders, the right cylinder consists of the balls undergone through the process of condensation.

This is because,

During condensation, the vapor molecules get converted into liquid.

And in the left cylinder, the balls evenly spaced have more intermolecular distance which designates the gaseous molecules.

While in the right cylinder, the layered form of gas shows that the conversion occurred to some state of molecules, having less intermolecular space.

And liquid has less intermolecular space than gas.

Thus, we can conclude that the change of state as depicted by the model is condensation.

Sonbull [250]

Answer:

See below

Explanation:

280 km   east then 190 km north

Use Pythagorean theorem to find the resultant displacement

d^2 = 280^2 + 190^2

d = 338.4 km

Angle will be    arctan ( 190/280) = 34.16 °
