Physical change and I think you mean soaked.
Answer:
The minimum magnetic field is 0.078 T.
Explanation:
Given that,
Current = 16 A
Side = 15 cm
Mass
Mass each segment in given square loop is
We need to calculate the torque due to gravity
Using formula of torque
The torque due to magnetic field
The equilibrium condition
Put the value into the formula
Put the value into the formula
Hence, The minimum magnetic field is 0.078 T.
The average distance from the Sun to Neptune is about 2.795 billion miles.
That's roughly 0.00048 of a light year .
Answer:
0.03 A
Explanation:
From the question given above, the following data were obtained:
Voltage (V) = 12 V
Resistor (R) = 470 Ω
Current (I) =?
From ohm's law, the voltage, current and resistor are related by the following formula:
Voltage = current × resistor
V = IR
With the above formula, we can obtain the current in the circuit as follow:
Voltage (V) = 12 V
Resistor (R) = 470 Ω
Current (I) =?
V = IR
12 = I × 470
Divide both side by 470
I = 12 / 470
I = 0.03 A
Thus, the current in the circuit is 0.03 A
