Answer:
a) 965,1 lbf
b) 4,5 kg
c) 1,33 * 10^6 dynes
Explanation:
Mass of an object refers to the amount of mattter it cotains, it can be expressed it gr, kg, lbm, ton, etc.
Weight of an object refers to a force, and is the measurement of the pull of gravitiy on an object. It may be definide as the mass times the acceleration of gravity.
w=mg
In Planet Earth, the nominal "average" value for gravity is 9,8 m/s² (in the International System) or 32,17 ft/s² (in the FPS system).
To solve this problem we'll use the following conversion factors:
1 lbf = 1 lbm*ft/s²
1 N = 1 kg*m/s²
1 dyne = 1 gr*cm/s² and 1 N =10^5 dynes
1 ton = 907,18 kg
1 k = 1000 gr
a) m = 30 lbm
b) w = 44 N
First, we clear m of the weight equation and then we replace our data.
c) m = 15 ton
pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.
<h3>What is pH?</h3>
pH is helps to determine if a solution is acidic or basic in nature.
A pH meter is the instrument that can be used for the measurements.
Methyl orange is used when titrating a strong acid against a weak base.
Therefore, the pH of the solution which is a weak acid will be between 4.0-7.0.

higher Ka value= stronger acid
stronger acids have weaker conjugate bases, so the acid with the strongest conjugate base would be acetic acid

Explanation:
22 Directions: Select the correct food web. In Ottawalley National Park, grass is abundant. Gazelles spend most of the day feeding on grass, their main source of food. Gazelles are hunted and eaten by the park's wild dogs. Lions are a predator of both wild dogs and gazelles. Which of the following food webs best represents the relationships described above? lion lion wild dog - wild dog gazelle gazelle grass grass lion lion wild dog wild dog gazelle gazelle grass grass
D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.
