Answer:
Reaction of calcium metal with water: Calcium forms calcium hydroxide along with hydrogen gas and heat when reacts with water. Reaction of magnesium metal with water: Magnesium metal reacts with water slowly and forms magnesium hydroxide and hydrogen gas.
Answer:
A) in the direction of current.
Explanation:
The magnetic field produced in a straight conducting wire on passing the current through it is in the direction of current.
The Right Hand Rule states that the magnetic field lines formed by the current wire are directed in the same direction as the curled fingers of the right hand of a human, with the thumb pointing in the direction of the current flow.
It is found that the field around a long straight wire is in circular loops. Rule 2 of the right hand (RHR-2) arises from this discovery and is true for any current segment point the thumb in the current direction, and curl the fingers in the direction of the magnetic field loops it produces.
