Answer:
Coefficient of friction is the ratio of friction force to normal force.
μ = F/N
It will land at 14139.19 m away.
Explanation:
The expression for range d on level ground is given by;
d=v² sin (2Ф) /g where Ф is the fire angle and g is acceleration due to gravity
Given v=400m/s ,Ф= 60° and g=9.8 so,
d= 400² sin(120°) /9.8
d=(400²×0.86602540378) / 9.8
d=14139.19 m

Georgia is moving by uniformly accelerated motion, with initial velocity
and with constant acceleration of
so her velocity at time t is given by
So now Georgia is running at 10 m/s.

Each atom emits or absors electromagnetic radiation, but only in some frequencies that are characteristic of its chemical element.
Now, if we supply energy in the form of heat (thermal energy) to a certain element in its gas phase, this will be stimulated and its atoms will emit radiation in certain frequencies of the visible spectrum, which constitute its <u>emission spectrum</u>.
If the same element, also in gaseous state, receives electromagnetic radiation, it absorbs in certain frequencies of the visible spectrum, <u>precisely the same ones in which it emits when it is stimulated by heat</u>. This will be its <u>absorption spectrum.</u>
<h2>
This means that every element absorbs radiation in the same wavelengths in which it emits it. </h2>
