Answer:
<h3>Our universe may live in one bubble that is sitting in a network of bubble universes in space. ... The concept is known as a "parallel universe," and is a facet of the astronomical theory of the multiverse. The idea is pervasive in comic books, video games, television and movies.</h3>
Chlorine gas or just chlorine?
Answer:
Explanation:
The question, translated, is:
- <em>A steel ball rolls and falls off the edge of a table from 4ft above the floor. If you hit the ground 5ft from the base of the table, what was your initial horizontal velocity?</em>
<em />
<h2>Solution</h2>
<em />
This is a projectile motion, for which, the equations that you will need are:
<u />
<u>1. Calculate the time that it takes the ball to fall 4ft</u>
<u />
<u>2. Calculate the horizontal velocity:</u>
The statement that describes the error in the work is that the distance must be converted to meters (m).
<h3>FORMULA FOR WORK:</h3>
Work can be calculated by using the following formula:
W = F × d
Where;
- W = work done
- F = force (N)
- d = distance (m)
According to this question, the force is given as 140N and the distance is given as 30cm. The force is calculated as follows:
F = 140N × 30cm = 4200J
This calculation is erroneous because the unit of distance should be converted from cm to meters.
