Pascal's law states that the pressure exerted on an incompressible fluid and in equilibrium within a container of non-deformable walls is transmitted with equal intensity in all directions and at all points of the fluid. In other words, it could be summed up further, stating that any pressure exerted on a fluid will spread over the entire substance evenly.
When Superman puts the stone on one side of the hydraulic system, the weight of the stone creates a pressure on the fluid that ends up being transmitted to lift the piston attached to the large stone. In order for the law of conservation of energy to exist and be maintained, the small stone has to move a lot so that the large stone moves only slightly, but moves safely.
Gaseous emissions are industrial products such as sulfur dioxide, carbon monoxide, and oxides of nitrogen also released during various manufacturing operations. Particulate control. Methods for particulate control tend to operate on a common principle.
Answer:
The answer is
<h2>56,000 kgm/s</h2>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
m = 1400 kg
v = 40 m/s
We have
momentum = 1400 × 40
We have the final answer as
<h3>56,000 kgm/s</h3>
Hope this helps you
Answer:
b. 1.1 m
Explanation:
It is given that the total distance between the masses is equal to the length of the board, which is 3 m. Therefore,

where,
s₁ = distance of fulcrum from left mass
s₂ = distance of fulcrum from right mass
In order to achieve balance, the torque due to both masses must be equal:

s₁ = 1.1 m
Hence, the correct option is:
<u>b. 1.1 m</u>
Answer: from the information given, the velocity of the water will decrease but the pipe size will remain the same.
