Answer:
C) Emf is the force exerted on a single charge to move it from one terminal to the other of an emf device.
Explanation:
Electromotive force, abbreviation E or emf, electrical energy per unit supplied from an energy source, such as an electrical generator or a battery. In the engine or battery, electricity is transformed from one source to another as the device works on the electrical charge that is passed within itself.
In physics it is defined as Work done by a cell or battery in moving a unit charge from its one terminal to the other, against the potential.
Hence C is correct
Answer:
4.88 K.
Explanation:
From the question given above, the following data were obtained:
Number of mole (n) = 5 moles
Pressure (P) = 1 atm
Volume (V) = 2 L
Gas constant (R) = 0.082 atm.L/Kmol
Temperature (T) =?
The temperature of the gas can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
1 × 2 = 5 × 0.082 × T
2 = 0.41 × T
Divide both side by 0.41
T = 2 / 0.41
T = 4.88 K
Therefore, the temperature of the gas is 4.88 K.
I think it’s false .
Let me know if it’s incorrect .
Answer:
at 
Explanation:
We need to calculate the components of the resultant force on both the x (horizontal) and y (vertical) direction.
Components of the first force F1:
Components of the second force F2:
So the components of the resultant force are
So the magnitude of the resultant force is
And the direction is
The magnitude of the acceleration can be found by using Newton's second law:
while the direction is the same as the resultant force, .
