Answer:
The velocity after 2 seconds can be found through:
V = u +a*t
Where V is final velocity, u is initial velocity, a is acceleration and t is time.
V = 0 + 2* 2= 4 meters/second
The distance (s) can be found through:
V^2= u^2 +2*a* s
Where V is final velocity, u is initial velocity, a is acceleration.
4^2= 0^2 + 2 *2*s
16= 0 + 4s
s= 4 meters
Distance (s) can also be found through:
s= ut + 1/2 at^2
s= 0+ 1/2 *2*2^2= 1 *2*2
s= 4 meters

Answer:
"A blackbody is an object that absorbs all of the radiation that it receives(that is,it does not reflect any light,nor does it allow any light to pass through it and out the other side).The energy that the blackbody absorbs heats it up,and then it will emit its own radiation."

Answer:
Correct answer: D = 10,800 m = 1.08 · 10⁴ m
Explanation:
None of the answers offered are correct.
The described motion is uniform with constant speed and the formula is:
D = v · t
Given: v = 15 m/s and time t = 12 min = 12 · 60 seconds = 720 seconds
D = 15 · 720 = 10,800 m = 1.08 · 10⁴ m
D = 10,800 m = 1.08 · 10⁴ m
