Hy tikki! I've asked some questions, so of you find the questions as easy, then answer it. I'll surely mark you as brainliest :)
Hi there!
Distance and displacement are different.
Distance is WITHOUT direction (scalar quantity)
Displacement TAKES INTO ACCOUNT direction (vector quantity), and is RELATIVE to the initial point.
DISTANCE:
Add up each segment's position:
0 - 2 sec: 0 m
2 - 5 sec: 10 - 4 = 6 m
5 - 6 sec: 0 m
6 - 8 sec: 10 - 2 = 8 m
8 - 9 sec: 0 m
9 - 12 sec: 5 - 2 = 3 m
Add up:
6 + 8 + 3 = 17 m
DISPLACEMENT:
To find displacement, simply look at the position at the final point (t = 12 sec) and compare to the initial position:
At t = 12: Position = 5 m
At t = 0: Position = 4 m
5 - 4 = 1 m
He's accelerating at 3 m/s² . That means his speed is increasing by 3 m/s every second.At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .He's been moving south for the whole 8 seconds.So at the end of that time, his velocity is 24 m/s south .
I agree a solar eclipse is when the moon is completely covered by the sun
Fusion occurs in the sun's innermost core, when two atoms merge, releasing energy and light in the process. Photons of light are first created in the sun's center. Over tens of thousands of years, the photons travel a "drunken walk," zigzagging their way from atom to atom until they reach the surface.
