Answer:
The wind blows wind energy causing the turbine to turn, the rotating shaft works the pump making mechanical energy.
The motion of water moving up from a well is kinetic energy.
Water in the tank, which is positioned 5 feet above the ground level is potential energy
Explanation:
The wind has in it wind energy which is then used to rotate the turbine shaft which is a form of mechanical work and hence possess mechanical energy
Moving water possesses kinetic energy and when this water is kept at some height it possesses potential energy
Answer:
Amount of heat required = 2810.5 J
Explanation:
Given data:
Mass of copper = 29.2 g
Initial temperature = 25°C
Final temperature = 275°C
Amount of heat required = ?
Solution:
Specific heat capacity of copper is 0.385 j/g.°C.
Formula:
Q = m×c×ΔT
ΔT = 275°C - 25°C
ΔT = 250°C
Q = 29.2 g × 0.385 j/g.°C ×250°C
Q = 2810.5 J
True because molo means two so you would need more than 1 atom
