Why do automobiles rust faster in wet climates than in drier climates?

The water helps the car slide just a little bit if you drive in a wet climate but in a dry climate the car does all the work. for example when you slide across ice with sneakers. on a dry surface you cant slide, but an a icy surface you start but the ice does the rest.

Automobiles rust faster in wet climate because  the chemical reaction between the metal and the iron, oxygen or water breaks down, or oxidizes, the metal causing the appearance of rust.

As the frequency of a wave increases the wavelength.
zaharov [31]

Answer:

decreases

Explanation:

Remeber:

There is always inverse relation between frequency and wavelength.

So if one of them increases, other decreases and vice-versa.

f ∝ 1 / λ

What is the order of magnitude of the distance of Sun to nearest star in meters?
neonofarm [45]

Answer:

Approximating the Milky Way as a disk and using the density in the solar neighborhood, there are about 100 billion stars in the Milky Way.

Explanation:

Since we are making an order of magnitude estimate, we will make a series of simplifying assumptions to get an answer that is roughly right.

Let's model the Milky Way galaxy as a disk.

The volume of a disk is:

V

=

π

⋅

r

2

⋅

h

Plugging in our numbers (and assuming that

π

≈

3

)

V

=

π

(

m

)

2

⋅

(

19

m

)

V

=

×

10

61

m

3

Is the approximate volume of the Milky Way.

Now, all we need to do is find how many stars per cubic meter (

ρ

) are in the Milky Way and we can find the total number of stars.

Let's look at the neighborhood around the Sun. We know that in a sphere with a radius of

4

×

10

16

m there is exactly one star (the Sun), after that you hit other stars. We can use that to estimate a rough density for the Milky Way.

ρ

=

n

V

Using the volume of a sphere

V

ρ

stars /

Going back to the density equation:

ρ

=

n

V

n

=

ρ

Plugging in the density of the solar neighborhood and the volume of the Milky Way:

n

n

n

stars (or 100 billion stars)

Is this reasonable? Other estimates say that there are are 100-400 billion stars in the Milky Way. This is exactly what we found.

In which state of matter are water molecules measured as having the lowest temperature?
natali 33 [55]
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

The y-component of a projectile’s velocity is 12.1 m/s. When the projectile once again passes by the height from which it was la
Nat2105 [25]
It's 12.1 m/s, assuming that's the launch velocity that's given.
For projectile motion, velocity's y-component is parabolic/quadratic. It's x-component is constant, so you don't need to know it.
