Gennadij [26K]

Answer:

The correct option is;

d) All of the above

Explanation:

a) In an electric circuit through which electric current flows, it is due to the electric charges which can be the negatively charged electrons or the positively charged protons

b) Voltage is the potential difference that results in current flowing through the circuit, therefore, the voltage is applied across the circuit through which current flows

c) The voltage which is the electric potential difference is the change in potential energy in joules of a given system due to the movement of a test charge (in Coulombs) between points in the electric field, ΔE, divided by the value of the test charge, 'q'

V = ΔE/q

Therefore, all of the above are correct.

What are the units of the following properties? Enter your answer as a sequence of five letters separated by commas, e.g., A,F,G
Marysya12 [62]

Answer:

The sequence is A,B,H,B,F

Explanation:

  • The Standard International unit is Kilogram (kg) and the mass of a body can also be expressed in gram (g).
  • Heat is a form of energy and the unit for energy is joule (J), thus the unit of heat is also joule (J).
  • Density is mass per unit volume where the unit of mass is gram (g) and the unit of volume can be taken as milli-liter (mL). Thus g/mL is the unit of density.
  • The unit of energy is joule (J).
  • Molarity is number of solute in mol dissolved in 1 liter of solution. Thus mol/L is the the unit of molarity.

Aleksei’s family purchased a new water heater that is a heat pump. After installation, Aleksei noticed that the room containing
rjkz [21]
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>
