Women earns
Answer:

Explanation:
The problem can be solved easily, because the relationship between intensities
and
at distances
and
respectively can be written as:
Where:

In this case:

Solving for 

Velocity is the rate of change in distance over change in
time, this can be written as:
v = Δd / Δt
While acceleration is the rate of change in velocity over
change in time, this is written as:
a = Δv / Δt
<span>Both quantities are vector quantities because negative
values means that the acceleration or velocity is acting on the opposite
direction.</span>
At the top of the waterfall, the water is higher in the gravitational field of the Earth and has gravitational potential energy. When it falls, the potential energy turns into kinetic energy.
Given :
Magnitude of vector, v = 15.3 m
Angle of vector from horizon,
.
To Find :
The x - component of the given vector.
Solution :
We know, a vector is given by :

Now, the x - component is :

Hence, this is the required solution.
