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.
B is the answer because it causes impact and collides together.
Answer:
Explanation:
We have,
Mass of Mars is, 
Mass of its moon Phobos, 
Distance between Mars and Phobos, d = 9378 km
It is required to find the gravitational force between Mars and Phobos. The force between two masses is given by
Plugging all values, we get :
So, the gravitational force is 
.
Answer:
Electromagnetic cranes are used to separate copper from iron in a scrap yard. The current is switched on to energies the electromagnet and pick up the iron pieces from the scrap. Then these iron pieces are moved to another position, the electromagnet in switched off and the iron pieces are released.
Explanation:
The unit for power is Watts. the newton is a unit for force. joules for energy and meters for distance
