Water displacement is the least difficult approach to decide the volume of an unpredictably formed or complex object. Rather than making various estimations and computations that might be inclined to error, it is just important to submerge the object in fluid and note the volume displaced. Ordinarily, this would be finished utilizing an aligned holder so the volume when inundation can be noted.
At the point when used to calculate the volume of a solid object, the drenching must be aggregate, and care taken to guarantee that no air is caught in any holes. Nonetheless, displacement can likewise be utilized to ascertain the heaviness of a vessel, in which instance obviously, the inundation isn't add up to; the vessel is permitted to drift and, as Archimedes broadly found, its weight will then be equivalent to that of the volume of water displacement.
Answer:
Gravitational potential energy
Explanation:
Hydroelectric dams are the power plants which generates electricity by using the energy of falling water from a great height.
A the water is stored in big reservoirs and at a great height, it contain lot of potential energy due to the height. As it falls downwards, the potential energy is converted into kinetic energy of the water. this kinetic energy of the falling water is used to run the turbine, and then the electric energy is generated.
So, in hydroelectric power stations, the potential energy of water is converted into the electric energy.
1) temperature
2) pressure
3) concentration
4) surface area
5) the presence of a catalyst
Answer:
The net force on the scooter is 95 N to the left.
Explanation:
Lizzie is pushing with 75 N of force to the left, so the force is a vector with 75N of magnitude and to the left.
Alex is helping with 20 N to the left, so the force is a vector with 20 N magnitude and to the left.
When we add vectors, vectors that point in the same direction add up and vectors that point in opposite directions are subtracted.
Hence, the net force is equal to:
F=75 N + 20 N=95 N
As both forces point to the left, the net force is also to the left.
Answer:
D. The net force on an object applied over a distance
Explanation:
Work can be defined as the product of force multiplied by a distance
Where
F = force [Newtons]
d = distance = [meters]
Therefore:
Work = F * d
Work in units of Joules [J]
