Answer:
The seed as a fraction of the speed of light is
Solution:
As per the question:
Suppose, be the rate of an identical clock between two time intervals.
For a moving clock, moving with velocity 'v', at the clock tick of four-fifth:
t =
Now,
Using the relation of time dilation, from Einstein's relation:
Squaring both sides:
Answer:
#_photon = 5 10²⁰ photons / s
Explanation:
For this exercise let's calculate the energy of a single quantum of energy, use Planck's law
E = h f
c= λ f
E = h c / λ
λ= 1000 nm (1 m / 109 nm) = 1000 10⁻⁹ m
Let's calculate
E₀ = 6.6310⁻³⁴ 3 10⁸/1000 10⁻⁹
E₀ = 19.89 10⁻²⁰ J
This is the energy emitted by a photon let's use a proportions rule to find the number emitted in P = 100 w
#_photon = P / E₀
#_photon = 100 / 19.89 10⁻²⁰
#_photon = 5 10²⁰ photons / s
The magnitude of the angular momentum of the rod immediately after the collision is given as (pf + pi) * d. (Option A).
<h3>
What is Angular Momentum?</h3>
Angular Momentum may be defined or described as the vector quantity of the rotation of a body, which is arrived at by multiplying its moment of inertia by its angular velocity.
The formula for Angular Momentum is given as:
L = <em>mvr; Where
L = Angular Momentum</em>
<em>m = mass</em>
<em>v = velocity; and </em>
<em>r = radius.</em>

Answer:
sorry I am not getting dear friend
Answer:
The west axis component of walk is, A = 5 miles
The east axis component of walk is, B = 8 miles
Explanation:
Given data,
The displacement of hiker south of west, R = 9.4 miles
The angle formed south of west, Ф = 60°
The vector components along,
the west axis is
A = R cosФ
A = 9.4 x cos 60
A = 4.7 miles
A = 5 miles
The west axis component of walk is, A = 5 miles
the south axis is
B = R sinФ
B = 9.4 sin 60
B = 8.14 miles
B = 8 miles
The east axis component of walk is, B = 8 miles
