Answer:
10,000J
Explanation:Joules is the si unit for work. To find work you must multiply
the force by the distance. force is measured in Newtons. 200N(Force)x50meters(distance)=10,000J(amount of work) plz mark brainliest.

Before the book is thrown, the potential energy has the highest amount, and when the book falls, the energy changes to energy movement, and when the book falls on the ground, the energy changes again to the potential energy.
Answer:
x is approximately 95.495
Explanation:
The given information are;
One lunar month = 30 days
The measured time between the first and third quarters = 14.9 days
Therefore, the angle of rotation for 30 days = 360°
The angle of rotation for 14.9 days = 14.9×360/30 = 178.8°
Therefore, whereby 2·θ = 178.8°
θ = 178.8°/2 = 89.4°
Therefore, given that the angle at the tangent from Sun to the Moon = 90°, we have;
The angle between the line from the Sun to the Moon = 90° - 89.4° = 0.6°
From sine rule, we have;
1/(sin 0.6) = x/(sin 90°)
x = (sin 90°)/(sin 0.6°) ≈ 95.495
x = 95.495.
Answer:
The bowlling shell's thickness is 2.7"
Explanation:
The geometry of the problem is based in the differences between the volumes in a small sphere and a spherical shell, both objects compose the total volume of the bowling ball.
The equivalence in the total ball height and the equivalent height in the fluid (in this case water displacement of half ball volume) is used for calculating the forces state that allows the static balance of the ball and the flotation force from the fluid (Archimedes principle).
In the image is showed the formulation.
