Answer:
84672 J
Explanation:
From the question given above, the following data were obtained:
Height (h) = 72 m
Combined mass (m) = 120 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Energy (E) =?
We can obtain the energy by using the following formula:
E = mgh
Where
E => is the energy.
g => is the acceleration due to gravity
m => is the mass.
h => is the height.
E = 120 × 9.8 × 72
E = 84672 J
Thus, the energy is 84672 J
Answer:
The final volume when pressure is changed is 126.1mL
Explanation:
Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:
P₁V₁ = P₂V₂
<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>
<em />
Computing the values of the problem:
350mmHg*200mL = 555mmHgV₂
126.1mmHg = V₂
<h3>The final volume when pressure is changed is 126.1mL</h3>
Answer:
See the answer below
Explanation:
<em>The carbon will have to travel in the form of CO2 from the atmosphere to a primary producer (green plant), from there to a primary consumer (herbivorous animal), and finally to a secondary consumer.</em>
The primary producer (a green plant) would fix the carbon in the CO2 to carbohydrate through a process known as photosynthesis. The equation of the process is as shown below:

The carbon, now in the form of carbohydrate, would then be picked up by an animal (a primary consumer) that feeds on the green plant. The carbon would eventually get into a secondary consumer when the secondary consumer feeds on the primary consumer that fed on the green plant.
