Answer:
5.865 μs
Explanation:
t₀ = Time taken to decay a muon = 2.20 μs
c = Speed of Light in vacuum = 3×10⁸ m/s
v = Velocity of muon = 0.927 c
t = Lifetime observed
Time dilation

∴Lifetime observed for muons approaching at 0.927 the speed of light is 5.865 μs

Explanation:
Answer:
a shiny smooth leaf
Explanation:
A shiny smooth leaf will cause specular reflection. Other choices will cause diffused reflection from the surface.
A specular reflection is similar to how a mirror or smooth surface reflects. The incident light is given off as a single ordered reflection from the surface of a body.
For this to occur, the surface incident must be smooth and without rough patterns on it.
A path way with rough rocks, small patch of soil and rough logs will give off diffused reflection
Answer:

Explanation:
Given equation:

To solve the given equation:


Multiply both sides by T₀:

Add 100 to both sides:

Subtract
from both sides:

Factor out the common term T₀:

Divide both sides by 

Carry out the calculation:
