1) The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation. protection of internal organs
2) Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
3)A joint is a point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint

Describe the electromagnetic spectrum, electromagnetic waves, and give two examples of different types of electromagnetic waves.
Answer:
1 mile
Explanation:
We can use the following equation of motion to solve for this problem:
where v m/s is the final take-off velocity of the airplane, 
initial velocity of the can when it starts from rest, a is the acceleration of the airplanes, which are the same, and 
is the distance traveled before takeoff, which is minimum runway length:
From here we can calculate the distance ratio
Since the 2nd airplane has the same acceleration but twice the velocity
So the minimum runway length is 1 mile
