A certain fan is capable of using 4800J of electrical energy each minute, converting 4000J of it into kinetic energy of the fan.
lapo4ka [179]

Answer:

Energy Ouput (Useful) / Total Energy Input = 4000 / 4800 = .833

E = 83%       assuming 4800 is actually input to fan

Infer When one object heats another, does the temperature increase of one object always equal the temperature decrease of the ot
scoray [572]

Answer:

No

Explanation:

When one object heats another, the amount of heat transferred by the hotter object (Q_h) to the colder object is equal to the amount of heat absorbed by the colder object (Q_c):

Q_h=Q_c

The two amounts of heat can be written as:

Q_h=m_h C_h \Delta T_h

where

m_h is the mass of the hotter object

C_h is the specific heat capacity of the hotter object

\Delta T_h is the change in temperature of the hotter object

And

Q_c=m_c C_c \Delta T_c

where

m_c is the mass of the colder object

C_c is the specific heat capacity of the colder object

\Delta T_c is the change in temperature of the colder object

So we can write

m_h C_h \Delta T_h = m_c C_c \Delta T_c

or

\frac{\Delta T_h}{\Delta T_c}=\frac{m_c C_c}{m_h C_h}

We see that this ratio is not always equal to 1, since the two objects can have different masses and specific heat capacities: therefore, the changes in temperature are not equal.

What is Nature? How does it explain the human condition?
Lelechka [254]

Answer:

Explained below.

Explanation:

Nature is defined as all of the genes as well as hereditary factors that influence both the physical appearance and personality manifestations of any individual.

For example, a child could inherit certain physical traits and characters from his/her parents which in turn shapes the physique and personality of such an individual in the world.
