a scientist obtains a small block of sodium. Sodium is a soft silvery metal. She places the block of sodium in a beaker filled with 50mL of water. What are the reactants in this chemical reaction? and explain the evidence int the products for the chemical reaction?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
