Since the armature windings of a direct-current or universal motor are moving through a magnetic field, they have a voltage induced in them. This voltage tends to oppose the motor supply voltage and so is called "back electromotive force (emf)". The voltage is proportional to the running speed of the motor. The back emf of the motor, plus the voltage drop across the winding internal resistance and brushes, must equal the voltage at the brushes. This provides the fundamental mechanism of speed regulation in a DC motor. If the mechanical load increases, the motor slows down; a lower back emf results, and more current is drawn from the supply. This increased current provides the additional torque to balance the new load.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Voltage at the brushes is equal to what?
Ah, so.. back emf of the motor, plus the voltage drop across the winding internal resistance

The Head of State of Portugal is the President of the Republic, elected to a five-year term by direct, universal suffrage. He or she has also supervision and reserve powers. These powers are often compared[by whom?] with the "moderator power" that was held by the King in the Portuguese Constitutional Monarchy.[citation needed] Presidential powers include the appointment of the Prime Minister and the other members of the Government (where the President takes into account the results of legislative elections); dismissing the Prime Minister; dissolving the Assembly of the Republic (to call early elections); vetoing legislation (which may be overridden by the Assembly with a supermajority); and declaring a state of war or siege. The President is also the ex officio Commander-in-Chief of the Armed Forces.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): By what means is the President of the Republic elected?
Ah, so.. by direct, universal suffrage

In 2001, a voluntary agreement called the Harkin-Engel Protocol, was accepted by the international cocoa and chocolate industry to eliminate the worst forms of child labour, as defined by ILO's Convention 182, in West Africa. This agreement created a foundation named International Cocoa Initiative in 2002. The foundation claims it has, as of 2011, active programs in 290 cocoa growing communities in Cote d'Ivoire and Ghana, reaching a total population of 689,000 people to help eliminate the worst forms of child labour in cocoa industry. Other organisations claim progress has been made, but the protocol's 2005 deadlines have not yet been met.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of agreement was the 2001 Harkin-Engel Protocol?
Ah, so..
voluntary
