Answer:
The line charge density is
Explanation:
Given that,
Diameter = 2.54 cm
Distance = 19.6 m
Potential difference = 115 kV
We need to calculate the line charge density
Using formula of potential difference
Where, r = radius
V = potential difference
Put the value into the formula
Hence, The line charge density is
The time taken by the apple to drop from the tree to the ground is given as: t = √2h/9.81
<h3>What is the time taken by the apple to drop to the ground?</h3>
The time taken by the apple to drop from the tree to the ground is determined using the equation of motion under free fall.
The equation is given below as:
where;
h is not given
t = √2h/g
t = √2h/9.81
In conclusion, the time taken is derived from the height and the acceleration due to gravity.

Answer:
The current would be 0.12A
Explanation:
Well, the formula for electric current is
where i is current, q is charge and t is time. Then we have to calculate the charge. If we know that the charge of a proton is , then we calculate the charge of 1500 protons as it follows:
So the current for each square meter of Earth's surface is
Finally, knowing the surface of the Earth is 510065284702000 , we can calculate the total current
Answer:
Large Hadron Collider
Explanation:
My favorite is the Large Hadron Collider. It is 16.6 miles and a new version is expected to be built that is 62 miles long. It is incredibly interesting to me how they are able to separate individual atoms and make them travel through the collider at light speed and then smash them into each other at these speeds. What's even more interesting is that on November 7 of 2010 they managed to create a mini-big bang that created temperatures a million times hotter than at the center of the Sun.
