Answer:
The aceleration of an object is in the direction of the net force. If you push or pull an object in a particular direction, it accelerates in that direction. The aceleration has a magnitude directly proportional to the magnitude of the net force.

Answer: The mass of 0.5 mole of element ab is 81.67 g.
Explanation:
According to the mole concept, 1 mole of a substance contains . As, the mass of atoms is 0.49 g.
So,
Therefore, mass of 1 mole =
= 163.33 g/mol
Hence, mass of 0.5 mole of ab element is calculated as follows.
= 81.67 g
Therefore, the mass of 0.5 mole of element ab is 81.67 g.
They are called lubricants.

Answer:
Explanation:
The acceleration due to gravity is in the downward direction. This means that it will oppose the upward motion of the stone. This will cause the stone to stop and begin to fall. Therefore, the sign of the final velocity is negative, since it is in the downward direction. The final velocity is given by:
