Answer:
B. The surface of the Earth heats the air that contacts it.
Explanation:
Conduction is a mode of heat transfer in which energy is transferred from a hot molecule to the neighboring molecules due to contact. Thus, heat energy is transferred from one molecule to another in the process.
Therefore, the air that comes in contact with the surface of the earth heats up by conduction. Since the surface of the earth is heated up due to the radiation from the Sun.
Answer: B.
Explanation: I took the test. Also, after my diagnostic I just wanted to see if my answers were correct lol.
orientation
distance
direction
Answer:
Distance
Explanation:
Isometry preserves the distance while transformation is made in between metric spaces. When a metric space is mapped on to another or itself, the distance between two points remains same in the images in the mapped space as well. Example: rotation and translation.
Thus, isometry preserves the distance.
Answer:
distance
Explanation:
b. Environmental physician, environmental veterinarian
c. Environmental activist, oceanographer, ecologist
d. Oceanographer, Environmental journalist
Correct answer choice is:
B. Environmental physician, environmental veterinarian.
Explanation:
Environmental medicine is a field involving several academic disciplines including physicians, environmental science, chemistry and many other related fields, protruding with environmental diagnostics. The extent of this domain includes examining the interplay's between ecosystem and human health, and the role of the atmosphere in producing or negotiating infection. Likewise, In the wildlife division, doctors are frequently defied with the outcomes of environmental contaminants and contagious infection disorders that probably endanger wild and housebroken animals as well as individuals.
Answer:
Work = (500N)(15m)=7500J Power= (7500J)/(20s) =375 W
Hopefully this helps
Explanation:
-___________
Latency heat is that heat which is either released or absorbed when a substance changes its physical state at constant temperature eg. from solid to liquid at the melting point or from liquid to gas at boiling point.
The change of phase always occurs with a change of heat. However the temperature does not change because that heat energy is used to overcome cohesive forces between molecules of that substance, no part of heat energy is used to increase the kinetic energy of the molecules. Similarly, heat energy is released and molecules of that substance comes closer but temperature doesn't decrease. So its temperature will not rise/decrease since the kinetic energy of molecules remains the same.
It is a horizontal line along x-axis.
Explanation :
The resistance of the flashlight is 2.4 ohms
The current flowing in the circuit is 2.5 A
The Ohm's law gives the relation between the following quantities i.e.
Current
voltage
and resistance
Mathematically, Ohm's law can be written as :
V =I R
The voltage applied by the batteries is 6 volts.
Hence, this is the required solution.
