The elbow is considered to be a lever, which is a simple machine. Other levers apart from the elbow are jaw, ankle, knee, etc.
This means that it is false that the <span>elbow is an example of a compound machine found in the human body.</span>
9.8 m/s is the acceleration due to gravity
<span>So we want to know which Newtons law explains the reaction when we bump into the coffee cup the coffee is spilled out. So Newtons 1st law says that a body stays in motion or it stands still until a force acts on that body. So we acted by a force on the coffee cup and the coffee continued to move even if there was no force on the coffee after we bumped the coffee cup.</span>
So we want to know what will happen to the needle of a compass that is held upright and pointing left in front of the solenoid if the current in the solenoid is reversed. If the current is reversed in the solenoid then the direction of the magnetic field of the solenoid is also reversed. So the needle that was pointing left will now point right after the direction of the current is changed.
