Answer:
First law: kinetic energy is used to turn an electric generator
Second law: some thermal energy is lost to the environment as it travels through the system
Explanation:
The first law of thermodynamics is known as the law of conservation of energy. It states that energy can neither be created nor destroyed but can only be transferred or changed from one form to another. When thermal energy is used to generate electricity, the kinetic energy of the steam is used to turn the electric generator (thereby producing electrical energy).
The second law of thermodynamics states that energy transfer or transformation leads to an increase in entropy resulting in the loss of energy. This law also states that as energy is transferred or transformed, some is lost in a form that is unusable. When thermal energy is used to generate electricity, some of the thermal energy is lost to the environment as it travels through the system.
Answer:
60000 newtons
Explanation:
Force=mass × acceleration
60000
Answer:
only thing I think of when I see that is 'Just Wondering'
Explanation:
Potential energy = mass x acceleration due to gravity x height
= 2.5 x 9.8 x 2.2
= 53.9 J.
Hope this helps!
Answer:
0.6 pound.
Explanation:
From the question given above:
Julie applies 2.67 Newton (N) of force down onto the table.
Hence, we can obtain the force in pound applied by Julie on the table as follow:
Recall:
1 N = 0.225 pound
Therefore,
2.67 N = 2.67 × 0.225
2.67 N = 0.6 pound
Therefore, the force in pound applied by Julie on the table is 0.6 pound
