The answer is D. Mountains in North America appear to be the same as those in Northern Europe
D. The atomic mass in amu is basically the number or nuclei since the mass of the electrons is negligible. For a given atom (element) the number of protons is fixed. Say the element has 10 protons. If the atomic weight is 14 atomic mass units (amu), you know that there are 4 neutrons, since both neutrons and protons are 1 amu each and there are 10 protons
A) lighting an electric lamp as it becomes darker
Answer: because of the magnetic
Explanation: If you hold a compass near a wire through which current is flowing, the needle on the compass will be deflected. Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing.
The work done on the given gas in one cycle is -405.3 kJ.
The given parameters;
- <em>initial pressure of the gas, P₁ = 2 atm</em>
- <em>final pressure of the gas, P₂ = 6 atm</em>
- <em>initial volume of the gas, V₁ = 1 m³</em>
- <em>final volume of the gas, V₂ = 3 m³</em>
Convert the pressure to Pascal (N/m²);
1 atm = 101325
The work done in one cycle is the area of the triangle and it is calculated as follows
the net work done on the gas = - 405.3 kJ
Thus, the work done on the given gas in one cycle is -405.3 kJ.
