The first one, as the mass is higher so it accelerates more
Answer:
A symbol for a battery.
Explanation:
A battery, because every sinlge circuit AC or DC must have a source of energy, to supply it to every single device that is part of the circuit.
The voltage is defined by the Ohm's law and it is equal to the product of the current by the resistance.
I think it’s R=U/I = 120/5 = 24
To develop the problem it is necessary to apply the concepts related to Magnetic Field.
The magnetic field is defined as

Where,
Permeability constant in free space
r = Radius
I = Current
Our values are given as,
B = 0.1T
d = 4.5mm
r = 2.25mm
If the maximum current that the wire can carry is I, then




Therefore the maximum current is 1125A
