Answer:
240 cm³
Explanation:
Weight = Buoyancy
mg = ρVg
m = ρV
(0.9 g/cm³ × 2400 cm³) = (1 g/cm³) V
V = 2160 cm³
The submerged volume is 2160 cm³, so the volume above the surface is 240 cm³.
Answer:
Explanation:
The torque of a force is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the centre of rotation of the system
is the angle between the direction of the force and d
In this problem, we have:
, the force
, the distance of application of the force from the centre (0,0)
, the angle between the direction of the force and a
Therefore, the torque is
10+8 = 18
5+2 = 7
18-7 = 11
a) to the right by 11N.
The explanation of how the natural world works based on experimentation is ;A theory ( D )
A theory is proportionally related to an experiment because a theory is an informed /phenomenon based on facts approved or disproved by an experiment.
Therefore an explanation of how the natural world works should be factual based on experimentation. and not an opinion, while a law in science is developed based on ideal conditions and not natural world conditions.
Hence we can conclude that The explanation of how the natural world works based on experimentation is A theory.

Answer:
1,110,114.6 J
Explanation:
The height is 1857m, the mass is 61 kg, and the accelaration is 9.8 m/s^2. Plug in the equation GPE=h*m*a and you get 1,110,114.6.
h= height
m= mass
a= accelaration
GPE= gravitational potential energy
