Average velocity is given by the ratio of total displacement /total time taken in order to do that
thus it will be
30.5-50.0/3 = 6.5 m/s
S defined by the International Astronomical Union<span> (IAU), a light-year is the distance that </span>light travels in vacuum<span> in one </span>Julian year<span> (365.25 days). so if a planet </span><span>15 light-years away from Earth that is inhabitable by humans like us they have developed a very powerful telescope allowing them see what is happening on Earth if they look to the telescope today, they will see 15 years ago in the earth</span>
An example of using muscular strength would be doing things like lifting weights and things like that.
The box moved 0.73 m
<u>Explanation:</u>
Given data,
Magnitude 8.1 N Work on the box 5.9 J Clerk move a 4.4 Kg
Distance= work done on the box / Horizontal force on the magnitude
= 5.9/8.1
=0.728
Distance =0.73 m
The box moved 0.73 m
