Answer:
149.05J
Explanation:
Hello,
Data;
Weight = 12N
x = 80miles
Radius of the moon = 1079.4mi
W = mg
But gravity at moon = ⅙ the gravity on earth
12 = ⅙ × m
M = 2kg
Mass of the module = 2kg
K = F.x
F(x) = k / x²
2 = k / (1079.4)²
k = 2.33×10⁶
Work = ∫f.dx
work = ∫₁₀₇₉.₄¹¹⁵⁹ . (2.33×10⁶/x²).dx
Work = (-2.33×10⁶) ×(¹/₁₁₅₉ - ¹/₁₀₇₉)
work = 149.05J
We can only corelate the object's weight with the amount of water it was able to displaced.
If the water displaced was around 400N, then the amount of liter displaced is around 400 N (kg*m/s²) / 9.8 m/s² (earth's gravitational pull) which is equals to ~40.81 liters which should be the objects mass as the best assumption (1kg = 1L). As there is no direct link between the water displaced and actual object weight.

Average acceleration is 6.49 m/s²
</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 m/s
Final velocity, v = 22.2 m/s
Time, t = 3.42 s
Substituting
v = u + at
22.2 = 0 + a x 3.42
a = 6.49 m/s²
Acceleration is 6.49 m/s²
Average acceleration is 6.49 m/s²
Answer:
Explanation:
Features. A tornado is a swirling vortex or column of air with a hollow core. The circulating air often contains debris and dust and moves in an upward spiral at high speeds. The bottom of the tornado column makes contact with the ground, while the top of the tornado can extend 5 or more miles into the sky.
