Afaraday ice pail similar to the one you will use in the experiment is used in this question. the principle of its operation relies on the proportionality between the charge on the inner pail and the potential difference between the inner pail and ground. suppose the relationship between charge � and potential difference � is given by � = � ∙ 2.90 ×10gj^.when a blue wand and a white wand are inserted into the ice pail at the same time without the wands touching, the electrometer reading was +74.6 . when only the white wand was removed, the electrometer reading changed to −25.0 . (a) how much charge resides on the blue wand? (b) how much charge resides on the white wand? (c) when the two wands are held 4.75 �� apart, what is the magnitude of the force exerted on either wand, assuming each wand is considered a point charge? is the force attractive or repulsive? (d) if the charge of one electron is −1.60 × 10gjc�, how many electrons are on the blue wand? assume that no leakage of charge occurs and that the charge on the pail is the same as the charge on the wand recall that j ^_`a = 9.00×10c ��e �e.

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
