Answer:
2r
Explanation:
As we know that
The displacement is the total distance measured between the initial or start and final or destination point
If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point
We attached the diagram for better understanding
As per the diagram.
The displacement after half-circle is
AB = OA + OB
= r + r
= 2r

Explanation:
Easy ! EVERY element and every compound melts, then boils and becomes a gas, if you heat it to a high enough temperature. That includes iron, gold, water, salt, glass, almost any substance.
If a car is moving with uniform velocity, then there is
no net force acting on it.
The force of the engine is exactly enough to balance
the forces of friction and air resistance against the car.
Also notice that there can't be any centripetal force, and the
car can't be on a curve. If it's moving with "uniform velocity",
that means steady speed in a straight line.
