Answer:
The mass of the apples in the box are 1145.95 lb.
Explanation:
Given that,
Width = 3.5 ft
length = 3.5 ft
Depth = 2.75 feet
Density = 49.3 lb/ft³
We need to calculate the volume
Using formula of volume
Put the value
We need to calculate the mass
Using formula of density
Put the value into the formula
But porosity is 31 % so apples is 69% mass of total container.
So, Total mass in pounds is
Hence, The mass of the apples in the box are 1145.95 lb.
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:
800J
Explanation:
Using the formula for change in the internal energy of a system
∆U = Q - W
Q = heat added to the system
W =workdone by system.
We know the process is an adiabatic one then, there no addition/ removal of heat, then Q= 0
(∆U = -W )
Then substitute for W, we have
∆U = -[-800]
∆U= 800J
∆U = 800J
The global warming is because of the car pollution was the fire in the forest it makes the air one and the warm air grocery Pacific side which makes me glacier it mostly glacier and breaks down two bases and the rising of the water makes the global warming too much so people are trying to use this card and try to use cycles because of global warming .
