Answer:
When unbalanced forces act on an object at rest, the object will move. In the two examples mentioned earlier, the net force on the object is greater than zero. Unbalanced forces produced change in motion (acceleration) and the receivers of the forces - the piano and the rope - moved.
Answer:
An unbalanced force means that there are more than one forces with different directions or magnitudes affecting the object. In this case, the vector addition of the forces should be done. The vector addition will result a net force. The object will move in the direction of the net force.
Answer:
rev/s
Explanation:
= mass attached to each hand = 5 kg
= initial distance of masses in each hand = 1 m
= final distance of masses in each hand = 0.1 m
= moment of inertia of body = 5 kgm²
= initial total moment of inertia = 
= initial angular velocity = 1 rev/s
= final total moment of inertia = 
= final angular velocity = ?
Using conservation of angular momentum
rev/s
Ionic Bonding: The formation of an Ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal. Covalent Bonding: Bonding between non-metals consists of two electrons shared between two atoms.
