In the diagram to the right, the battery provides 12 V to the circuit made up of three identical light bulbs. When the switch is closed the voltage across bulb A will be A. 12 V.
B. 2 V.
C. 6 V.
D. 4 V.

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
