Answer:
(a) Both the charges are positive or negative.
(b) Teh value of each charge is 1.53 x 10^-5 C.
Explanation:
Spring constant, K = 340 N/m
Natural length, L = 0.4 m
stretch, y = 0.033 m
(a) Let the charge on each sphere is q and they repel each other so the nature of charge of either sphere may be both positive or both negative.
(b) The electrostatic force is balanced by the spring force.
0 to 30 takes more energy
Explanation:
In atomic bombs, nuclear reactions is at work.
Depending on the reaction, matter is converted to energy either by nuclear fusion or fission process.
- Nuclear reactions takes place in the nucleus of elements.
- Inside the nucleus, the bulk of the mass of atoms are concentrated via by the presence of protons and neutrons.
- These particles called nucleons typifies the mass of an atom.
- When nuclear reactions occur, they take place in the nucleus of atoms.
- This interaction leads to the conversion of some of these masses to energy.
- As predicted by the Einstein's equation, E = mc², mass m and energy E are both equivalent.
- c is the speed of light.
- Instead of converting all the mass to product, some are transformed into energy.
- The mass and energy equivalence typifies nuclear reactions.
- There is always a mass deficit that accompanies such reactions.

Answer:
4, 2, 5, 3, 1
Explanation:
The neuron remains at RMP unless stimulated. The stimulus results in opening of stimulus channels, this causes depolarization. if the extent of depolarization reaches to the level of threshold, the sodium and potassium channels begin opening but potassium channels are slow to open. Hence at first sodium goes out causing further depolarization until it reaches the peak at which the potassium channels open and the sodium channels close. This causes the potassium to rush our causing repolarization i.e. return of the membrane potential to RMP but the potassium channels are slow to close and it leads to hyperpolarization (undershoot) making the membrane potential more negative due to excessive movement of potassium outside the cell. Once the potassium channels close, the leak channels and Na K pump acts to return the potential to RMP.
