Answer:
D. the distance and direction to the water fountain
Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
- Displacement is a vector quantity with both magnitude and direction.
- To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
- The direction attribute distinguishes distance from displacement
- The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.
Answer: Kinematics
Explanation: Kinematics is a branch of mechanics focusing on describing motion of objects, excluding from consideration the study of forces that act on such objects.
Explanation:
by the formula, v²-u²=2aS
S=12m, a=2m/s², v=25m/s, u=?
v²-u²=2aS
25²-u²=2×2×12
-u²=48-625
-u²=-577
u²=577
u=√577
u = 24.02m/s

Answer:
turbine
Explanation:
Tidal energy is produced in the Tidal power plant to produce electricity. The kinetic energy is produced because of the energy of the tides in the form of moving water. This energy is converted into electricity with the help of power turbines. The turbine plays an important role in the production of electricity. The fluid that is used in the turbine contains potential energy. The moving turbine converts the potential energy to kinetic energy and the energy is collected in the form of electricity.
9.8 m/s^s and thats the earths gravitational force!
