Uso the compound interest formulas A=P(1 • a) "and A=Pe" to solve the problem given. Round answer to the nearest cont. Find the accumulated value of an investment of $25,000 for 4 years at an interest rate of 6% if the money is a. compounded semiannually; b. compounded quarterly; c.
compounded monthly; d. compounded continuously.
a. What is the accumulated value if the money is compounded semiannually?

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.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
