Who argued in 340 BC in his book “On The Heavens” that the world was round?
Aristotle
If you scuff electrons on your feet while walking across a rug, are you negatively or positively charged?
You have more electrons after you scuff your feet, so you are negatively charged, and the rug is positively charged.
What is the net charge of a charged capacitor?
The net charge of a charged capacitor is zero because the charges on its two plates are equal in number and opposite in sign
This Maryland Woman, born a slave around 1820, helped free slaves on the Underground Railroad
Harriet Tubman
Vin Diesel named his daughter Pauline after this late co-star of his
Paul Walker
Who proposed in 1913 that electrons could only orbit a nucleus at specific distances and only in limited quantity at distance?
Niels Bohr
A high-speed bus and an innocent bug have a head-on collision. The force of impact splatters the poor bug over the windshield. Is the corresponding force that the bug exerts against the windshield greater, less or the same?
The magnitudes of both forces are the same because they constitute an action-reaction force pair.
Put the four fundamental forces (the electromagnetic force, gravity, the strong nuclear force, the weak nuclear force) order of strongest to weakest
1) the strong nuclear force
2) the electromagnetic force
3) the weak nuclear force
4) gravity

Less
A circular circuit is powered by a 9V battery. How will the magnetic field change if a second 9V battery is added in the same direction as the first?
The magnetic field will double in magnitude and have the same direction.

Edwin Hubble
A skydiver jumps from a high-flying helicopter. As she falls faster and faster through the air, does her acceleration increase, decrease, or remain the same?
Acceleration decreases because the net force on her decreases. Net force is equal to her weight minus the air resistance, and since air resistance increases with increasing speed, net force and acceleration decrease.
In a linear magnetic medium, the bound current is suddenly doubled in size. What must have happened to the free current?
It was doubled in size too.
