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.
Answer:
Explanation:
Let the radius of the hemisphere is R. The mass is released from rest so the initial speed is equal to zero and acceleration is equal to the g.
By the Newton's 3rd equation,
Now, at the bottom hemisphere the centripetal acceleration will act on the mass and the direction of this force is towards center,
Hence, the acceleration on the bottom of the hemisphere is equal to the 2g.
Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
I hope this is useful for you

Answer:Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current. Electricity is a basic part of nature and it is one of our most widely used forms of energy.

The application of force over distance is known as [WORK]
