-A photon travels, on average, a particular distance, d, before being briefly absorbed and released by an atom, which scatters it in a new random direction.
-Given d and the speed of light, c, you can figure out the average time step and space step size (how often the photon “steps” and how far it “steps” each time).
-The size of the Sun is figured in terms of step size. Some surprisingly tricky math happens, involving “Brownian motion” and probabilities. Finally,
-The average time it would take to get to the surface of the Sun is found.
Answer:
68kg
Explanation:
1 cm^3 is the same as 1 mL and there are 5000mL in 5L
Therefore if the density is 13.6g/mL we multiply 13.6 by 5000 to get the amount of grams required = 68000g which is 68kg
A) Up is the direction of the magnetic field at point Z.
-- If acceleration and velocity are in the same direction,
then the object is speeding up.
-- If acceleration and velocity are in opposite directions,
then the object is slowing down.
-- If acceleration is perpendicular to velocity, then the object
is moving on a circular curve at constant speed.
Answer:
Total electric potential, 
Explanation:
It is given that,
First charge, 
Second charge, 
Distance of first charge from origin, 
Distance of second charge from origin, 
We need to find the total electric potential at the origin. The electric potential at the origin is given by :
V = 1321826.08 V
or
So, the total electric potential at the origin is 
. Hence, this is the required solution.
