Answer:
and there is no friction
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity.
Thats is instantaneous bc it’s in the moment
D) chemical change, irreversible.
This is because if two liquids made a solid when mixed together, it was most likely a chemical change (especially is bubbles were produced!), and a chemical change is permanent!
The inter molecular force of attraction between molecules decreases with increase in temperature. Because due to increase in temperature, the kinetic energy of the molecules increase and they starts moving with higher velocity.
