How do Scientists think our sun was created, or born? Question 3 options: Other life forms constructed gravitational hydrogen atoms that pulled together to create the sun. The force of gravity pulled more and more material into the center of this swirling disk. Eventually, the pressure in the center was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy. The sun was genetically constructed in a laboratory and released into the atmoshere and allowed to coninue it's nuclear fission until it was large enough to be a sun Scientists have never investigated the sun

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
