You can't increase a transformer.
You can't increase a circuit.
You can't increase a generator.
When the <em><u>current</u></em> through a coil of wire increases, the magnetic field
around the coil increases, so there would be more magnetic force
between the coil and a permanent magnet.
Power = (voltage) x (current)
Power = (240 volts) x (4 Amp)
Power = 960 watts
I can help you with 5. 5 is a displacement-time graph.
At A it is moving in a positive direction and speed is constant.
At B it is stationary or at rest.
At C, movement is negative and it is decreasing or decelerating
At D, it’s a general downwards movement in the negative direction that can be described as overall constant
B. They are rearranged.
The First Law of Thermodynamics states that matter and energy can not be created or destroyed.
