Question 1: What subject model do many Chinese provinces use for the Gaokao?

Answer

The 3+1+2 model: three core subjects, one choice of physics or history, and two electives.

The core three are Chinese, mathematics, and a foreign language. Students then pick physics or history plus two electives, and each province sets its own paper format.

Question 2: A ball is dropped from rest and falls 4.9 m. With g = 9.8 m/s^2 and no air resistance, how long is the fall?

Answer

1.0 s.

Starting from rest, distance is (1/2)gt^2. Solving 4.9 = 4.9t^2 gives t = 1.0 s.

Question 3: An arithmetic sequence starts at 2 and increases by 3 each term. What is the 10th term?

Answer

29.

The nth term is a1 + (n - 1)d. With a1 = 2, d = 3, and n = 10, the term is 2 + 9 x 3 = 29.
