The hotter an object is, the more kinetic energy it has, but i'm not sure what is the exact word missing??
<span>The acceleration of an object is equal to the change in velocity over time. Or alternatively, the acceleration of an object is equal to the initial velocity minus the final velocity over the time taken to change from the initial velocity to the final velocity.</span>
B because the electrons are moving to create a new form. Chemical energy is changing the form.
Hope this helps.
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

5m/s because all you have to do is add 3 and 8
