Increasing
Explanation:
If a ship is moving forward and has a positive acceleration, we can say that the velocity of the ship is increasing.
Velocity is the rate of change of displacement of a body with time.
Acceleration is the rate of change of velocity with time.
Acceleration =
If a ship is moving with positive acceleration, the velocity of the ship is increasing also.
- This is because when velocity is increasing, the change will be positive.
- From the equation, to have positive velocity, the final velocity must be greater than the initial one.
- With this, acceleration will be positive.
- So we can say, velocity of the ship is increasing.

Answer:
14.57 ohms
Explanation:
Here in the figure ,Rb & R₄are in series & also Rc & R₅ are in series. As they are in series , ( Rb + R₄ ) & (Rc & R₅) are in parallel . So the equivalent resistance in that branch = ( 2 + 18 ) ║ ( 3 + 12 )
= 20 ║ 15
= (20×15) / (20 + 15)
= 8.57 ohms
Also Ra ( 6 ohm ) is in series with that branch ,. So the equivalent resistance of the whole circuit = 8.57 + 6 = 14.57 ohms.
