Like mass and energy, it is already part of the natural phenomena that momentum is always conserved. However, just like energy, there are exception to this rule. This is when an external force is applied to the system which causes it to work reversely. <em>Therefore, momentum is conserved when no net external force is applied. </em>
Answer:
B. Each joint has a different range of motion.
Explanation:
The range of motion for each joint needs to be measured separately as each joint has a different range of motion depending on the type and placement of the joint, for instance ball and socket joints have more movement than a hinge joint.
also, observe the joints that connect your head with your body and the joint that connect your arm with your palm. The joint that connect your head and your body allow a 360 degree movement which is why you can spin your head around while the joint that connect your palm and your arm only allow 180 degree movement.
Red dwarf stars evolve very differently than other stars as they age because <u>their </u><u>interiors </u><u>are well mixed, through strong convection.</u>
<h3>
What are red dwarf stars?</h3>
Red dwarf stars are the smallest and coolest kind of stars on the main sequence.
Red dwarf stars (stars between 0.08 and 0.5 solar masses) evolve very differently than other stars as they age because <u>their </u><u>interiors </u><u>are well mixed, through strong convection.</u>
