Answer

How about a thunder storm. I don't know if you live in a city or out in the sticks as I do. Lighting is very obvious and it is not a good idea to be out when experiencing a thunderstorm, especially in an open field. You might be the only thing around that will cause the lightning to be connected to the ground.# Seconds later, you will hear the thunder which is quite harmless. If you live in the city, observing this is not quite so easy. There are all kinds of buildings around and some of them may block your view.

#The great golfer, Lee Travino, was "hit" by lightening storm twice while playing in tournaments.

I think the answer is: 6 inches

On average, the distance between Car's engine to the ground is around 8-10 inches.. But for small cars, the distance between car's engine to the ground could be as low as 5 inches - 6 inches from the ground.

When the flood reach the car's engine level, the water will got into the engine and disrupt it function, causing the car became unable to work properly

an object that is 8 cm tall is located 2.5 m in front of a plane mirror. The image formed by the mirror appears to be. Find di a

UkoKoshka [18]

The image is at 2.5 m behind the mirror (virtual image)

Explanation:

We can solve the problem by using the mirror equation:

$\frac{1}{f}=\frac{1}{d_o}+\frac{1}{d_i}$

where

f is the focal length of the mirror

$d_o$ is the distance between the object and the mirror

$d_i$ is the distance between the image and the mirror

For a plane mirror, the focal length is infinite:

$f=\infty$

And in this problem, the distance of the object from the mirror is

$d_o = 2.5 m$

Substituting and solving for $d_i$ , we find the location of the image:

$0=\frac{1}{d_o}+\frac{1}{d_i}\\d_i = -d_o = -2.5 m$

And the negative sign means that the image is located behind the mirror, so it is virtual.

Which is the relationship between photon energy and frequency?

hichkok12 [17]

Photon has no rest mass but when photon travels at the speed of light, it gains momentum.
The energy of the photon is E= pc, c = speed of the photon and p= its momentum.

∴ E = pc
but p = h/λ (This comes from De-broglie's theory)

∴ E = hc/λ

frequency = ν = c/λ
∴E = hν
