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.

hammer [34]

For every action, there is an equal and opposite reaction. For example, take a cup on a table. The weight of the cup is the action, and the reason the cup does not sink through the table is because the table exerts an equal reaction force which is opposite to the action of the cup.

Hope this helps!

A commercial jet liner takes off with an average acceleration of 3 g. How long does it take to reach the end of its runway which

ANEK [815]

Answer:

The time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.

Explanation:

Given;

average acceleration of the commercial Jet liner, a = 3g = 3 x 9.8 m/s² = 29.4 m/s²

distance traveled by the commercial Jet liner, s = 1542 m

The time taken for the commercial Jet liner to reach the end of its runway is calculated as follows;

s = ut + ¹/₂at²

where;

u is the initial velocity of the commercial Jet liner = 0

s = 0 + ¹/₂at²

s = ¹/₂at²

2s = at²

$t = \sqrt{\frac{2s}{a} } \\\\t = \sqrt{\frac{2 \times 1524}{29.4} } \\\\t = 10.18 \ s$

Therefore, the time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.

Dorji weight 1500n.if the total surface area of soles of his feet is 0.5 m2 what is the pressure exerted by his body on the grou

Fantom [35]

Answer:

P = 3000 Pa

Explanation:

Weight of Dorji, W = F = mg = 1500 N

The total surface area of soles of his feet is 0.5 m²

We need to find the pressure exerted by his body on the ground. The pressure is equal to the force acting per unit area. So,

$P=\dfrac{1500\ N}{0.5\ m^2}\\\\=3000\ Pa$

So, the pressure exerted by his body on the ground is 3000 Pa.

A turtle crawls at 4.32 m/s to cover the short 3.84 m distance to his food bowl. How long does it take?

Lyrx [107]

Speed=Distance/Time. so you need to do distance/speed to get time. 3.84/4.32= .88888888889 seconds to get to his food bowl
