Problem: Text: Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver. The terminal velocity depends on many factors including mass, drag coefficient, and relative surface area and will only be achieved if the fall is from sufficient altitude. A typical skydiver in a spread-eagle position will reach terminal velocity after about 12 seconds, during which time he will have fallen around 450 m (1,500 ft).

Question: is there a terminal velocity in a vacuum?

OPTIONS:
- no
- yes
A: yes

Problem: Text: The European Union value added tax (or EU VAT) is a value added tax on goods and services within the European Union (EU). The EU's institutions do not collect the tax, but EU member states are each required to adopt a value added tax that complies with the EU VAT code. Different rates of VAT apply in different EU member states, ranging from 17% in Luxembourg to 27% in Hungary. The total VAT collected by member states is used as part of the calculation to determine what each state contributes to the EU's budget.

Question: is vat the same in all eu countries?

OPTIONS:
- no
- yes
A: no

Problem: Text: Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by the Earth's magnetic field lines. This angle varies at different points on the Earth's surface. Positive values of inclination indicate that the magnetic field of the Earth is pointing downward, into the Earth, at the point of measurement, and negative values indicate that it is pointing upward. The dip angle is in principle the angle made by the needle of a vertically held compass, though in practice ordinary compass needles may be weighted against dip or may be unable to move freely in the correct plane. The value can be measured more reliably with a special instrument typically known as a dip circle.

Question: will the dip be the same everywhere in the world?

OPTIONS:
- no
- yes
A:
no
