Answer:
electromagnetic wave. this energy is what lights the bulb.
Explanation:
When you close an electrical circuit, the electrons have a small drag speed, but the fluctuation of the electric field that is created originates by Lenz's law a magnetic field and the appearance of this magnetic field creates a fluctuating elective field, these two fields together forms a wave called an electromagnetic wave.
This electromagnetic wave has a speed given by the relation
v = √1 /ε μ
in a vacuum this speed is equal to the speed of light, which is worth 3 10⁸ m/s this very high value so the energy transported by this wave can travel the distance of 10 m in less than 10⁻⁷ s, This energy is what lights the bulb.
Radioactive decay is the loss of elementary particles from an unstable nucleus, ultimately changing the unstable element into another more stable element. There are five types of radioactive decay: alpha emission, beta emission, positron emission, electron capture, and gamma emission.
what? I guess:
- practice different habits. If you fail don't give up.
- don't always trust people, some are not what they seem.
this question doesn't make any sense...
Answer:
The extent of greenhouse effect on mars is
Explanation:
From the question we are told that
The albedo value of Mars is 
The albedo value of Mars is 
The surface temperature of Mars is 
The surface temperature of Venus is 
The distance of Mars from the sun is 
The distance of Venus from sun is 
The radius of the sun is 
The energy flux is 
The solar constant for Mars is mathematically represented as
![T = [\frac{E R^2 (1- A_1)}{\sigma d_m} ]](https://tex.z-dn.net/?f=T%20%3D%20%5B%5Cfrac%7BE%20R%5E2%20%281-%20A_1%29%7D%7B%5Csigma%20d_m%7D%20%5D)
Where
is the Stefan's constant with a value 
So substituting values


So the greenhouse effect on Mars is



Answer:
D. Banks and offices closing on sunday.
Explanation:
Church is usually on sunday and people need a day off to do it because service is about 3 hours long. When banks and offices close on this day it shows how religion has affected our lives and our culture.
