Answer:
128379.69 J
Explanation:
Potential energy: This can be defined as the energy of a body to to position in the gravitational field. The S.I unit of potential energy is Joules (J).
The expression for potential energy is given as,
ΔEp = mgΔH
ΔEp = mg(H₂-H₁)..................... Equation 1
Where ΔEp =change in Potential Energy, m = mass of the man, g = acceleration due to gravity, H₂ = Height of the 37th floor, H₁ = height of the first floor
Given:m = 91.2 kg, g = 9.8 m/s², H₁ = 3.99 m, H₂ = 3.99×37 = 147.63 m.
Substitute into equation 1
ΔEp = 91.2(9.8)(147.63-3.99)
ΔEp = 893.76(143.64)
ΔEp = 128379.69 J.

Answer:
Total Resistance in circuit is Fourteen Ohms <u>(14 Ω).</u>
<u></u>
Explanation:
How do we know, if the resistors are connected in series, the total resistance is the <u>sum of all the resistors.</u>
(Important: The total resistance can only be added just when the resistors are <u>connected in series</u>)
Then, total resistance (<em>TR </em>) is the sum of all resistors (<em>T1 + T2</em>, in this case)
TR = T1 + T2
According to problem data, we have:
TR = 8 Ω + 6 Ω
TR = 14 Ω

<u>Given</u><u>:</u>
- An object has a forward force = 100N
- An object has a reverse force = 25N
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
What is the resultant force?
<u>Solution</u><u>:</u>
Resultant Force = Forward force + Reserve force
= 100 N + ( - 25 N )
= 75 N
