Ammonia is a weak base ( electrolyte) because ammonia reacts with water to produce ammonium and hydroxide ions. When hydroxide ion reacts with ammonium, it results to water and ammonia. it only proves that ammonia is rather a base because of its acceptance of hydrogen ion from water.

Ammonia is a weak base because it produces ammonium and hydroxide ions. Weak bases are so called weak because in the solution, these bases do not fully convert itself into hydroxide ions or in other words, it does not fully ionize in the solution.

Magnitude of u = 15, direction angle θ = 35° Magnitude of v = 18, direction angle θ = 60° Find the magnitude and direction angle

djverab [1.8K]

Answer:

32.225 and angle is 48.7 degree.

Explanation:

u = 15, θ = 35 degree

v = 18, θ = 60

First represent the u and v in vector form.

u = 15 (Cos 35 i + Sin 35 j ) = 12.287 i + 8.6 j

v = 18 ( Cos 60 i + Sin 60 j ) = 9 i + 15.6 j

The sum of the two vectors is given by

u + v = 12.287 i + 8.6 j + 9 i + 15.6 j = 21.28 i + 24.2 j

Magnitude of u + v = $\sqrt{21.28^{2}+24.2^{2}}$ = 32.225

Let Ф be the angle

tan Ф = 24.2 / 21.28

Ф = 48.7 degree
