Aleksei’s family purchased a new water heater that is a heat pump. After installation, Aleksei noticed that the room containing

the new water heater felt cooler than the rest of the house.
What is the best explanation for why the room with the heat pump was cooler than the rest of the house?

a) Thermal energy from the water was transferred to the surrounding air.
b) The burning fuel increased the thermal energy in the air.
c) Thermal energy from the air surrounding the water heater was transferred to the water.
d) The burning fuel absorbed thermal energy from the surrounding air.

A heat pump is a device used to heat something, in this case water. Heat pump takes heat from colder object and transfers it to warmer object. This is opposite to <span>direction of spontaneous heat transfer which from warmer to colder object.

In this problem a room got colder while water got warmer. This is due to work done by heat pump. This is what is described in correct answer c).
a) is not correct because it shows </span>direction of spontaneous heat transfer. It also says that <span>Aleksei’s family purchased a new water heater and in description givne in a) it would mean that water got colder.
b) is not correct because if the </span><span>burning fuel increased the thermal energy in the air it would mean that this room got warmer than rest of house.
d) is not correct because burning fuel does not absorb </span><span>thermal energy. It releases it.</span>

cestrela7 [59]

Answer:

Explanation:

We Often solve the the integral neutron transport equation using the collision probability (CP) method which usually requires flat flux (FF) approach. In this research, it has been carried out in the cylindrical nuclear fuel cell with the spatial of mesh with quadratic flux approach. This simply means that the neutron flux at any region of the nuclear fuel cell is forced to follow the pattern of a quadratic function.

Furthermore The mechanism may be referred to as the process of non-flat flux (NFF) approach. The parameters that calculated in this study are the k-eff and the distribution of neutron flux. The result shows that all parameters are in accordance with the result of SRAC.

If earth increase the distance from the sun, what will happen to the period of orbi t(the time it takes to complete one revoluti
Mandarinka [93]

The period of the orbit would increase as well

Explanation:

We can answer this question by applying Kepler's third law, which states that:

"The square of the orbital period of a planet around the Sun is proportional to the cube of the semi-major axis of its orbit"

Mathematically,

\frac{T^2}{a^3}=const.

Where

T is the orbital period

a is the semi-major axis of the orbit

In this problem, the question asks what happens if the distance of the Earth from the Sun increases. Increasing this distance means increasing the semi-major axis of the orbit, a: but as we saw from the previous equation, the orbital period of the Earth is proportional to a, therefore as a increases, T increases as well.

Therefore, the period of the orbit would increase.

ASAP PLZZ FINALS TOMR GIVE U ALOT OF POINTSS
Annette [7]

Answer:

B

Explanation:

Let m be mass of the object and v be speed of object b.

Kinetic Energy of B = 1/2 mv^2

Kinetic Energy of A = 1/2 m(2v)^2

= 2 mv^2

= 4 (1/2 mv^2)

= 4 × Kinetic Energy of B

Hence Object A has four times the kinetic energy of object B (<em>A</em><em>n</em><em>s</em><em> </em><em>B</em><em>)</em>
