B24& co stock has a beta of 1.62, the current risk-free rate is 3.12 percent, and the expected return on the market is 10.62 percent. what is b24& co's cost of equity?

cost of equity = 23.05 %

Explanation:

given data

beta = 1.62

risk free rate = 3.12 percent

expected market return = 10.62 %

to find out

B24&Co's cost of equity

solution

we get here cost of equity that is express as

cost of equity = risk free rate + beta rate × ( expected market return - risk free rate )    1

put here value we get

cost of equity = 3.12% + 1.62 × ( 10.62% - 3.12% )

cost of equity =  3.12% + 1.62 × 7.50%

cost of equity = 3.12% + 19.93 %

cost of equity = 23.05 %

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.
