Nebular cloud should be the answer, but i believe nuclear fusion is the closest answer, because it fuses together to become a cloud 

hope this helps

A ball is projected horizontally from a table 1.0 m high and hits the ground after falling from a time t=0.45s. If the ball trav
photoshop1234 [79]

The initial velocity is 6.7 m/s

Explanation:

The motion of the ball is a projectile motion, therefore it consists of two independent motions:  

- A uniform motion (constant velocity) along the horizontal direction  

- A uniformly accelerated motion, with constant acceleration (acceleration of gravity) in the downward direction  

In this problem, we just need to analyze the horizontal motion: the horizontal velocity is constant, therefore the horizontal distance travelled is given by

x=v_x t

where

v_x is the horizontal velocity

t is the time of flight

Here we have:

t = 0.45 s

x = 3.0 m

And so solving for v_x, we find

v_x = \frac{3.0}{0.45}=6.7 m/s

And since the ball was initially projected horizontally, this is also the initial velocity.

A car accelerates uniformly from rest for a time of 12 sec. The rate of acceleration is 4m/s^2. What is the velocity at the.end
Natali5045456 [20]

initial velocity = 0 = v₍i₎

final velocity = ? = v₍f₎

t = 12 sec

Acceleration = 4m/s²

First we have to find the distance d, for this we use the formula,

D = v₍i₎t + 1/2at²

D = 0(12) + ½ (4)(12)²

Distance = d = 288 m

Now to find the Vf use the formula,

V₍f₎² = v₍i₎² + 2ad

V₍f₎² = (0)2 + 2(4)(288)

V₍f₎² = 2304

V₍f₎ = 48 m/s

so the velocity at the end of 12 sec is 48 m/s
