The current passing through a circuit consisting of a battery of 12 V and resistor of 2 ohms is 6 Ampere .
Explanation:
- Assume the wires are ideal with zero resistance.
- The current passing through the circuit will be
I = V/R = 12/2 = 6.000 A.

Answer: Yes
Explanation: A molecule has a bond dipole but not have a molecular dipole.
Dipole moment: dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.
Example:
lets take an example of molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.
due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.
Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.
Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.

Explanation:
Given:
- mass of heavier student,
- mass of lighter student,
- velocity of the heavier student after the mutual push,
1)
Since they push each other and we are neglecting any friction that means we can consider this as a perfectly elastic collision. So the momentum of the two bodies will be equal and in opposite direction.
Since momentum is a vector quantity so the total momentum of the system as a whole will be zero.
2)
<u>From the condition of elastic collision:</u>
