Complete the statement below.

in a neutralization reaction, and hydroxide ions react to

Explanation:

Hydrogen and hydroxide ions reacts to form water in a neutralisation reaction

, water

Explanation:

A base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions in water.

Neutralization reaction  is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.

photocells convert light energy to electricity

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
