Chemistry
Consider the following intermediate chemical equations. 2H (g) + O2(g) → 2H, O( H (9)+F (9) ► 2HF(g) In the final chemical equation, HF and O2 are the products that are formed through the reaction between H2O and F2. Before you can add these intermediate chemical equations, you need to alter them by multiplying the O second equation by 2 and reversing the first equation. O first equation by 2 and reversing it. O first equation by (12) and reversing the second equation. second equation by 2 and reversing it.

Ответ:
GP.E = 5880 j
Explanation:
Given data:
Mass = 75 kg
height = 8 m
Potential energy = ?
Solution:
The formula for gravitational potential energy is
GPE = mgh
m = mass in kilogram
g = acceleration due to gravity
h = height in meter above the ground
Formula:
GP.E = mgh
Now we will put the values in formula.
g = 9.8 m/s²
GP.E = 75 Kg × 9.8 m/s²× 8 m
GP.E = 5880 Kg.m²/s²
Kg.m²/s² = j
GP.E = 5880 j
