Well, the quantity alone doesn't point to any one particular process.
I mean, you could get 3.826 x 10²⁶ watts of heat out of a pile of
smoldering charcoal IF the pile was big enough and you kept it
supplied with enough oxygen.

The thing about the sun is that ==> it can churn out energy at that rate
from the mass that it has, ==> it has already been doing that for so many
billions of years, and ==> it will continue doing that for so many more
billions of years in the future.

The only possible process able to accomplish that is nuclear fusion.

An astronaut is out in space with an extremely precise timing device measuring the speed of various fast‑moving objects. A laser
Leviafan [203]

Answer and Explanation:

with reference to Einstein's theory of special relativity, the speed of an electromagnetic radiation, here, laser will not change in any inertial frame or remains same irrespective of any change in inertial frame.

Therefore, the speed of light measured in both the cases, i.e., in astronaut's reference frame and spaceship's reference frame will be equal to the speed of light in vacuum, i.e., 3\times 10^{8} m/s.

The laser gun's speed in astronaut's reference frame is the same as the speed of the spaceship as it mounted on it, i.e., the speed of the laser gun is 200 million m/s.

The laser gun's speed measured in spaceship's reference frame will be zero, as it is mounted on the spaceship and is stationary in the spaceship's reference frame.

The electromagnetic wave shown above is made up of vibrating Electric fields. 

I assume this is why electromagnetic waves can travel through a vacuum, due to lack of matter.

A spring has a spring constant of 20N/m. What force does the spring exert on you if the spring is compressed - 0.25 m ?
Triss [41]

Answer:

5N

Explanation:

Data obtained from the question include:

K (spring constant) = 20N/m

e (extension/compression) = 0.25 m

F (force) =?

Using the formula F = Ke, the force can be obtained as follow:

F = Ke

F = 20 x 0.25

F = 5N

How far apart are two conducting plates that have an electric field strength of 4.5 × 103V/m between them, if their potential
nalin [4]

Answer:

Explanation:

Given

Electric Field Strength E=4.5\times 10^{3}\ V/m

Potential Difference between Plates is given by V=12.5\ kV

In conducting plates a Potential difference exist between two plate which accelerate the charge when put between the conducting plates

The potential difference is given by

\Delta V=Ed

where E=Electric Field strength

d=distance between Plates

d=\frac{\Delta V}{E}

d=\frac{12.5\times 10^3}{4.5\times 10^{3}}

d=2.78\ m
