The Potential Energy, is given by:
where:
m = mass of the object (in Kg)
g = gravity
h = height (in m)
Hence:

Answer:
Brainliest pls C.
Step-by-step explanation:
Answer: 76 meters
Step-by-step explanation:
top side left blank = 18 because it is congruent to the bottom
left side blank is 4 + 4 + 4 (right side lengths added)
left side blank is 12
add all side lengths together for perimeter
12 + 18 + 4 + 8 + 4 + 8 + 4 + 18 = 76
76 meters
Answer:
37
Step-by-step explanation:
x = 1st number
y = 2st number
z = 3rd number
x + y + z = 235
y = x + 15
z = 8x
x + x + 15 + 8x = 235
10x = 220
x = 22
y = 37
z = 176
Answer:
43.77°
Step-by-step explanation:
The height, h = first floor to basement = 9.2 feets
Length of staircase = hypotenus = 13.3 feets
Angle stacase makes with basement floor, θ
Using trigonometry :
Sinθ = opposite / hypotenus
Opposite = height = 9.2 feets
Sinθ = 9.2 / 13.3
Sinθ = 0.6917293
θ = sin^-1(0.6917293)
θ = 43.77°
