Hey!!
here is your answer >>>
We know that, acids and strong bases are good conductors of electricity!. And gold conducts electricity , while the best is silver and niext comes gold!. And H20 which is water contains less ions , so it is not a good conductors , it is a conductors but not a good conductor!. Salt in it's solid for cannot produce ions, hence, it cannot conduct electricity , but when this salt is mixed with water or when it is in it's molten state it can conduct electricity!. So now,the answer for the question is ,
B) III and IV only!.
Hope my answer helps!
Answer:
The ball will continue to move at a constant speed forever until another force stops it.
Explanation:
Newton's first law of motion can be seen as a law of inertia. It explains that an object at rest or in a state of uniform motion will remain in that state unless it is acted upon by an external force.
Following the above, when the ball is thrown into space, the ball will continue to move with the velocity with which it was thrown until it comes in contact with another object that stops it. If this does not happen, it will continue to drift forever at that velocity.

Answer:
During high fever a wet cloth is kept on the forehead of a person to decrease the temperature of body. ... When the wet cloth is placed on the forehead, water in wet cloth starts to evaporate and it starts to absorb a lot of heat from our body. Hence it is used to decrease the temperature of body.
Velocity = displacement / time
displacement = velocity × time
d = 29 ms⁻¹ ˣ 8.4 s
d = 243.6 m
