The principle that
describes the force on a charge in a magnetic field was named for Hendrik Lorentz, and the principle
is named as Lorentz force.
Hendrik Antoon Lorentz<span> <span>(18 July 1853 – 4 February 1928) was a Dutch </span></span>physicist<span> <span>who shared the 1902 </span></span>Nobel Prize in Physics<span> <span>with </span></span>Pieter Zeeman<span> <span>for the discovery and theoretical explanation
of the </span></span>Zeeman effect<span>.<span> </span></span>
1. Friction (Example: when you rub your hands together and you start to feel heat.)
2. Attract each other. (Example: Every object has a gravitational pull of some sort. The larger the object, the stronger the gravitational pull. This is why the sun is able to keep all eight planets in orbit around it.)
3. Hope this helped :)

Answer:
d = 2.45 meters
Explanation:
Mass of the ball, m = 0.5 kg
Radius of the circle, r = 0.16 m
The angular speed of the ball around the circle is, 
The attached figure shows the whole scenario. Let 
is the force acting on the ball in tangential direction. The forces will balanced each other at equilibrium.
In horizontal direction,
................(1)
In vertical direction,
...............(2)
From equation (1) and (2) :
Also,
d = 2.45 meters
So, the value of d is 2.45 meters. Hence, this is the required solution.
The Audi covers 88 in one hour.
22 is one quarter of 88, so it takes one quarter of one hour. That's 15 minutes.
Note:. The answer would be the same for any other brand of car, motorcycle, airplane etc.
