Explanation:
The given data is as follows.
Mass of small bucket (m) = 4 kg
Mass of big bucket (M) = 12 kg
Initial velocity (
) = 0 m/s
Final velocity (
) = ?
Height 
= 2 m
and, 
= 0 m
Now, according to the law of conservation of energy
starting conditions = final conditions
235.44 = 
+ 78.48
= 4.43 m/s
Thus, we can conclude that the speed with which this bucket strikes the floor is 4.43 m/s.
They hit the ground at the same time
Answer:
Explanation:
A later study in 2012 found a cluster of galaxies beginning to form 600 million years after the Big Bang. Another study in 2012 called the Extreme Deep Field honed in on the center of the HUDF and detected galaxies forming just 450 million years after the Big Bang.
When did we discover another galaxy?
The Andromeda nebula was really the Andromeda galaxy. This discovery implied that the other, even fainter, spirals were probably also galaxies even farther away. Hubble published his work in 1929 and changed forever our view of the universe. Astronomers no longer thought our galaxy was the entire universe.
ANY force causes an object to accelerate, just as long as there are not
some other forces on the object that cancel out the first one.
Are you looking for the answer ... an "UNBALANCED" force ?
That's a very poor way to describe it, because there's no such thing
as a balanced or unbalanced force. The thing that's balanced or
unbalanced is a GROUP of forces, not a single force.
An object is 16.0 cm to the left of a thins lens. The lens forms an
image 36.0 cm to the right of the lens.
