The Newton's law that explains why the hands get red when you press them hard against a wall is Newton's third law. When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
Magnetic flux Ф is given by
Ф = ∫В.dA
dA is an element of area of the surface, the integration is carried over the entire surface through which we wish to calculate the flux. B is magnetic field.
If direction of coil is remained the same, area of the coil remains the same. But as we increase the magnetic field, the number of field lines passing through the coil increases. Therefore the magnetic flux will increase.
Thank you for posting your question here at brainly. Below is the solution:
E = (h * c) / λ
<span>E = h * f </span>
<span>E = (6.626E-34 J*s) * (6.00E14 Hz) </span>
<span>E = 397.5642E-21 Joules </span>
<span>E = 397.5642 zeptoJoules </span>
V=IR
= 2 x 6
= 12V
Resistors in series add together:
(2ohms x 2) + (1ohms x 2)
4 + 2 = 6 ohms
Hope this helps!
