Which statement accurately describes the big bang theory? The universe began at an outer boundary and has been collapsing since
iren [92.7K]

Answer: The statements are missing hence I will give you a summary of what the big bang theory .

answer : The big bang theory explains how the energies of every speck of the universe came together at a point ( very dense point ) and eventually exploded creating the various galaxies we have today

Explanation:

The Big bang theory describes how the Universe and the various galaxies that exist began some billion of years ago, It describes how the energies of every speck of the universe came together at a point ( very dense point ) and eventually exploded creating the various galaxies we have today

The velocity of a ball as it is thrown up is 20 meters/second. It attains zero velocity after 3.5 seconds. What is the average a
Step2247 [10]

Change in speed = (speed at the end) minus (speed at the beginning)

                           =                    (0 - 20 m/s)  =  -20 m/s

Acceleration = (change in speed) / (time for the change)

                           =  (-20 m/s)      /   (3.5 sec)   =   -5.71 m/s²

Notice that this story probably didn't happen on Earth, because
the acceleration due to gravity on Earth is  9.8 m/s².

A charged particle is accelerated in a uniform electric field. When its velocity is 2 m/s, its electric potential energy is 100
zavuch27 [327]

Answer:

particle's potential energy = 70J

Explanation:

From conservation of energy; K1 + Ue1 = K2 + Ue2

where K1 and K2 are the kinetic energies at two positions and Ue1 and Uue2 are the electrical potential energies at two positions.

k1 = 10J, Ue1 = 100J

K2 = 40J

substitute into K1 + Ue1 = K2 + Ue2

Ue2 = K1 + Ue1 - K2

= 10 +100 - 40

Ue2 = 70J
