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>

Answer:d
Explanation:
Suppose V is the voltage of battery and R is the resistance of bulb
so Power drop for initial stage

When another identical bulb of same resistance is applied in parallel so voltage Drop across both the resistor will be same i.e. V
so Power consumed 
so there is no change in power and hence no dip in brightness
