<h3>Answer: 2 seconds</h3>
This problem is equivalent to kicking the ball 8 m/s and it rolls to a point 16 meters away, and everything is on a flat ground (with no cliff). This is because the horizontal component of the velocity does not get affected by how tall the cliff is and the force of gravity. Note how the height of the cliff isn't even mentioned. So that's a clue that we can ignore it.
If x is the number of seconds, then 8x is the distance in meters it travels. So we have 8x = 16 solve to x = 2. The ball travels for 2 seconds before reaching its target.
Answer:
Explanation:
The water droplet is initially neutral, it will obtain a 40 nC of charge when a charge of -40 nC is removed from the water droplet.
The charge on one electron,
Let the N number of electrons have charge -40 nC, such that,
Now, mass of one electron =
Therefore, mass of N electrons =
It is the mass of the of the water droplet that must be removed in order to obtain a charge of 40 nC.
Let it is m times the total mass of the droplet which is
Then,
It is the required fraction of mass of the droplet.
