Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5.0 m/s2. which one of the following statements accurately describes the motion of this particle?
a. the particle travels 5.0 m during each second.
b. the particle travels 5.0 m only during the first second.
c. the speed of the particle increases by 5.0 m s during each second.
d. the speed of the particle increases by 5.0 m s2 during each second.

Correct option is (C)

Explanation:

u = 0 m/s

a = 5 m/s^2

(a) Distance traveled by the particle in first second

s = ut + 1/2 at^2

s = 0 + 0.5 x 5 x 1 x 1 = 2.5 m

So, this option is wrong.

(b) As we observe by the part (a) that the particle travels a distance of 2.5 m in first second so, this option is wrong.

(c) The acceleration of the particle is 5m/s^2, it means the speed of teh particle increases by 5 m/s every second. So, this is true.

(d) As we observe by part (c), the speed of the particle increases by 5 m/s every second so this option is wrong.  

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
