Explanation:
A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.
Answer:
The lifetime of the particle is
Explanation:
From the question we are told that
The average rest energy is
The intrinsic width is
The lifetime is mathematically represented as
Where h is the Planck's constant with a value of
substituting values
C) decomposition because the molecules are breaking down (decomposing)
Answer:
B) 6 W
Explanation:
First of all, we need to find the work done by the force. This is given by
where
F = 4 N is the magnitude of the force
d = 3 m is the distance through which the force is applied
Substituting,
Now we can find the power, which is given by
where
W = 12 J is the work done by the force
t = 2 s is the time taken
Substituting,
