Answer:

The combinations are

1. 2\times 10^{-4} C , 15\times 10^{-4}

2. 3\times 10^{-4} C , 10\times 10^{-4}

Explanation:

The force between two charges q and Q is given by Coulomb's law.

The coulomb force is given by

F = \frac{1}{4\prod \varepsilon _{0}}\times \frac{Q\times q}{r^{2}}

Where, r be the distance between two charges

According to the question,

r = 15 cm, Q = 6\times 10^{-4} C, q = 5\times 10^{-4} C , F = 12 N

Force remains same, distance remains same

so the product of Q and q be same

The product of Q and q is 30\times 10^{-8}

So other combination of charges are

1. 2\times 10^{-4} C , 15\times 10^{-4}

2. 3\times 10^{-4} C , 10\times 10^{-4}

Mama L [17]

Answer:

The maximum emf induced in the ring

= (2.882 × 10⁻⁷) V

Explanation:

According to the law of electromagnetic induction, the emf induced in the ring is given by

E = N BA w sin wt

The maximum emf induced is

E = N BA w

B = 30.5 μT = (30.5 × 10⁻⁶) T

A = (πD²/4)

D = 1.75 cm = 0.0175 m

A = (π×0.0175²/4) = 0.000240625 m²

Nw = 2π × 6.25 = 39.29 rad/s

E = 30.5 × 10⁻⁶ × 0.000240625 × 39.29

E = (2.882 × 10⁻⁷) V

Hope this Helps!!!

When a solid is in the process of changing into a liquid and extra energy is added to the system, the temperature does not chang
Alekssandra [29.7K]

Answer:

D. The temperature does not change during a phase change because the average kinetic energy does not change. Therefore, the potential energy in the bonds between molecules must change.

Explanation:

When there is a change of state (for example, from solid into a liquid, as in this example), when energy is added to the system, the temperature of the substance does not change.

The reason for this is that the energy supplied is no longer used to increase the average kinetic energy of the particle, but instead it is used to break the bonds between the different particles/molecules. For instance, since in this case the substance is changing from solid to liquid, all the energy supplied during the phase change is used to break the bonds between the molecules of the solid: when the process is done, all the molecules will be free to slide past each other, and the substance has turned completely into a liquid.

The bonds between molecules store potential energy: therefore, this means that the energy supplied during the phase change is not used to change the kinetic energy, but to change the potential energy in the bonds between the molecules.
