The three main types of articulations withing the human body are FIBROUS, CARTILAGINOUS AND SYNOVIAL.
Another word for articulation is joint. A joint refers to a point of contact between two bones or between a cartilage and a bone. A joint is said to be fibrous, if the bones are held together by fibrous connective tissues. A joint is described as cartilaginous, if a bone is joined to a cartilage. A synovial joint is one in which the bones are joined by various ligaments.
Answer: warm and rainy
A warm front is the transition zone which develop in a region where warm air replaces the cold air. The air behind the warm front is warmer than air in the front. When the warm front reaches a region with colder air, the cold air gets warm and more humid. Warm front brings changes in weather condition of a region. The increase in humidity in air results in rainfall and temperature becomes warm.
Therefore, a warm front heading toward Chicago will result in warm and rainy weather.
Force = Mass * Acceleration ........................ (that is all know)
<span>Force is given= 3200N </span>
<span>Mass is= 160 Kg </span>
<span>Acceleration= ? </span>
<span>F = M*A </span>
<span>F/M=A </span>
<span>3200/160=A </span>
