When Nellie hangs at rest by a pair of ropes, the tensions in the ropes

• always equal her weight
• always equal half her weight
• depend on the angle of the ropes to the vertical
• are twice her weight

moving at constant speed and in straight line motion

• Static Equilibrium
• Dynamic Equilibrium
• Weight
• Normal Force
